Surgical and chemical sympathectomy can alter cellular proliferation

Surgical denervation and chemical sympathectomy can alter cellular proliferation, B- and T-cell responsiveness and lymphocyte migration in lymphoid organs [17].

In vitro studies have shown that neuropeptides can have numerous effects, either inhibiting or stimulating the proliferation, differentiation and functions of immune cells [19]* Development of systemic lupus erythematosus in mice is associated with alteration of neuropeptide concentrations in inﬂamed kidneys and immunoregulatory organs

Acquired cardiovascular disease following Sympathectomy

We found statistically significant differences (P < .05) in both time and frequency domains. Parameters that evaluate global cardiac autonomic activity (total power, SD of normal R-R intervals, SD of average normal R-R intervals) and vagal activity (rhythm corresponding to percentage of normal R-R intervals with cycle greater than 50 ms relative to previous interval, square root of mean squared differences of successive normal R-R intervals, high-frequency power, high-frequency power in normalized units) were statistically significantly increased after sympathectomy. Low-frequency power in normalized units, reflecting sympathetic activity, was statistically significantly decreased after sympathectomy. Low-/high-frequency power ratio also showed a significant decrease, indicating relative decrease in sympathetic activity and increase in vagal activity.

RESPONSE TO SYMPATHETIC BLOCKADE DEPENDS ON THE DEGREE OF SYMPATHETIC TONE BEFORE THE BLOCK

Denervation of preganglionic cardiac accelerator fibres leaving the cord at T1-T5 results in minimal vasodilatory consequences. Changes however in heart rate, left ventricular function and myocardial oxygen demand may occur due to high thoracic epidural blockade and are discussed below.

The major determinant of heart rate is the balance between sympathetic and parasympathetic systems with the latter predominating. A high thoracic epidural anaesthesia (TEA) covering the cardiac segments (T1-T4) produces small but significant reductions in heart rate4-8. During cardiac sympathetic denervation, parasympathetic cardiovascular responses, including those involved in baroreflexes, may dominate.

Individual cardiovascular response to different levels of sympathetic blockade varies widely, depending on the degree of sympathetic tone before the block.

decreased conditioning-related activity in insula and amygdala after autonomic denervation

The degree to which perceptual awareness of threat stimuli and bodily states of arousal modulates neural activity associated with fear conditioning is unknown. We used functional magnetic neuroimaging (fMRI) to study healthy subjects and patients with peripheral autonomic denervation to examine how the expression of conditioning-related activity is modulated by stimulus awareness and autonomic arousal. In controls, enhanced amygdala activity was evident during conditioning to both "seen" (unmasked) and "unseen" (backward masked) stimuli, whereas insula activity was modulated by perceptual awareness of a threat stimulus. Absent peripheral autonomic arousal, in patients with autonomic denervation, was associated with decreased conditioning-related activity in insula and amygdala. The findings indicate that the expression of conditioning-related neural activity is modulated by both awareness and representations of bodily states of autonomic arousal.

cell body reorganization in the spinal cord after surgery for sweaty hands

The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.

Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

Spinal cord infarction occurring during thoraco-lumbar sympathectomy
J Neurol Neurosurg Psychiatry 1963;26:418-421 doi:10.1136/jnnp.26.5.418

In conclusion, our results suggest that cross-inhibitory control by various afferents in the spinal cord may exist in the feet as well as in the contralateral hand. The release of cross-inhibitory control by T3 sympathicotomy results in vasoconstriction and a decrease of skin temperature on the contralateral hand and the feet.

The basic neuronal network for this reciprocal organization is probably located in the spinal level (15). Therefore, the reduction in the contralateral skin temperature may be explained by cross-inhibitory control of various afferent in the spinal cord.

Segmental myoclonus was associated with thoracic sympathectomy

Spinal myoclonus was associated with laminectomy, remote effect of cancer, spinal cord injury, post-operative pseudomeningocele, laparotomy, thoracic sympathectomy, poliomyelitis, herpes myelitis, lumbosacral radiculopathy, spinal extradural block, and myelopathy due to demyelination, electrical injury, acquired immunodeficiency syndrome, and cervical spondylosis.

Spinal myoclonus is typically associated with a localized area of damaged tissue (focal lesion). The injured area may include direct damage of the spinal cord or may cause abnormal changes in the function of the spinal cord.

hyperhidrosis is not related with social phobia or personality disorder

The total reward dependence and persistence scores were significantly higher in hyperhidrosis patients. The fear of uncertainty in the harm avoidance scale was found to be significantly greater in hyperhidrosis patients. Regarding character dimensions, the total score in each of the subscales self-directedness, cooperativeness and self-transcendence was found to be higher in hyperhidrosis patients. Conclusion: The higher scores of all subscales of character dimensions in hyperhidrosis patients suggest that hyperhidrosis is not related with social phobia or personality disorder.

Effects of upper abdominal sympathectomy on gastric acid, serum gastrin, and catecholamines

Selective upper abdominal sympathectomy increased basal acid output in rats but was without effect on stimulated acid output, serum gastrin concentration, and gastric mucosal histidine decarboxylase activity. The sympathectomy was verified by fluorescence histochemistry and determination of tissue catecholamines. A drastic reduction in tissue noradrenaline, adrenaline, and dopamine levels occurred after sympathectomy, and fluorescence microscopy showed a complete loss of adrenergic nerve fibers. Vagotomy reduced catecholamine levels in the stomach wall by 50% but did not affect the catecholamine content in the pancreas and small bowel. Surprisingly, combined vagotomy and upper abdominal sympathectomy resulted in lower catecholamine levels than sympathectomy alone in extragastric but not in gastric tissues.

ATELECTASIS IS A COMMON PULMONARY COMPLICATION FOLLOWING THORACIC AND UPPER ABDOMINAL PROCEDURES

General anesthesia and surgical manipulation lead to atelectasis by causing diaphragmatic dysfunction and diminished surfactant activity. The atelectasis is typically basilar and segmental in distribution. After induction of anesthesia, atelectasis increases from 1 to 11% of total lung volume. End-expiratory lung volume is also found to be decreased.

Postoperative atelectasis is extremely common. Lobar atelectasis is also common. The incidence and prevalence of this disorder are not well documented.

http://emedicine.medscape.com/article/296468-overview#a0104

Atelectasis occurs regularly after induction of general anesthesia, persists postoperatively, and may contribute to significant postoperative morbidity and additional health care costs. Laparoscopic surgery has been reported to be associated with an increased incidence of postoperative atelectasis.

the muscles that are supplied by these nerves shorten and tighten (due to the supersensitivity

This now well-established but generally under-appreciated principle of physiology is aptly known as 'Cannon's Law of Denervation Supersensitivity'. It describes the wide ranging effects of the complete loss of nerve inputs to a variety of bodily structures under experimental conditions. One of the many responses to nerves that are sick or dysfunctional (now termed Disuse Supersensitivity) is that the muscles that are supplied by these nerves shorten and tighten (due to the supersensitivity of both the muscle's specialized stretch receptors and motor nerve-muscle junctions), resulting not only in muscle spasm and stiffness which limit flexibility, but a whole sequence of pain compounding reactions. The two earliest are that localized taut bands of muscle fibers begin to compress the small specialized pain sensing (and now extra-sensitive) nerve fibers within the muscle (known as myofascial tender or trigger points) causing type 1 pain, and the compressed muscles do not allow proper blood flow in, or waste products to be removed. This leads to a build up of lactic acid, which further enhances the perception of pain through type 2 pain mechanisms. Continued and prolonged muscle shortening or contracture gradually leads to increased mechanical tension on the muscle's tendonous attachments to bone, causing all of the various tendonitis (types 1 & 2 pain) syndromes throughout the body. The end result is a truly vicious snowballing cycle of pain, with the muscle shortening further increasing pressure on the nerves.

www.northwestims.com/faq-4.html

Cannon's law of denervation tells us that if a post-ganglionic neurone has it's pre-ganglionic input removed, then it will become super-sensitive to the normal neurotransmitters that mediate that pre-ganglionic input. There is a variety of reasons for this, including up-regulation of receptors for the neurotransmitter(s), post-receptor effects, and impaired removal of neurotransmitters from the synapse

Most authors do not describe clinically significant capsular adhesions as a predominant finding in the chronic phase of this condition. Instead, pathologic data confirm an active process of hyperplastic fibroplasia and excessive type III collagen secretion that lead to soft-tissue contractures of the aforementioned structures (ie, the coracohumeral ligament, soft tissues of rotator interval, the subscapularis muscle, the subacromial bursae). However, these findings were observed in surgical patients who had severe and late-phase disease and cannot be applied to early phases of the disease.

From the chromosomal, cytochemical, and histologic points of view, the soft-tissue contractures are identical to those seen in a Dupuytren contracture of the hand. These contractures result in the classic progressive loss of ROM of the glenohumeral joint, which affects external rotation and abduction, then flexion, adduction, and extension (in descending order of severity). Despite these histopathologic similarities, the favorable and regressive outcome of adhesive capsulitis differs from the unfavorable and progressive outcome of Dupuytren disease.

slowing of the heart rate usually occurs on the second to fourth day after sympathectomy

The rate fell to a level between 40 and 6o per minute, the maximal slowing usually occurring on the second to fourth day after operation. Consistent slowing of the rate was not observed after a unilateral thoracic sympathectomy of either side. While there was some recovery from the maximum bradycardia with the passage of time in most patients, relatively slow resting cardiac rates and failure of tachycardia to develop with postural hypotension or exercise persisted in all patients.

Skoog's12 work has shown that there are marked differences in the number and precise location of the accessory ganglion cells in the cervical region in different patients and on the two sides in the same patient.

LIMITED SYMPATHECTOMY DOES NOT REDUCE SEVERITY OF SIDE-EFFECTS

Limited sympathectomy does not reduce severity of side-effects

On univariate and multivariate analysis, the extent of denervation was not associated with the occurrence or the severity of compensatory sweating.

Compensatory sweating and temporary relief/recurrence were equally considered to be the main causes of dissatisfaction. CONCLUSION: Compensatory sweating was the most common long-term complication of thoracodorsal sympathectomy for primary hyperhidrosis. Its incidence and severity were not associated with the extent of sympathectomy.

Receptor hypersensitivity is a common problem

Because of their size and location, injuries to the sympathetic ganglia or chain is rarely indicated or performed. Receptor hypersensitivity is a common problem after significant sympathetic injury, including clammy hands, erythema, and allodynia. When sympathetic nerves regenerate, they may establish aberrant connections to sensory receptors, muscles, or other sympathetics receptors; this may lead to an over-response or abnormal response.

Complications in patients with palmar hyperhidrosis treated with transthoracic endoscopicsympathectomy.

Neurosurgery. 1997 Jul ;41 (1):110-3; discussion 113-5 9218302

OBJECTIVE: To assess the complications in a group of patients with palmar hyperhidrosis treated with transthoracic endoscopic sympathectomy. The extraordinarily high incidence of postoperative compensatory hyperhidrosis in our series is stressed and explained. METHODS: The retrospective study included chart reviews and outpatient assessments. Seventy-two patients underwent T2 or T2-T3 endoscopic sympathectomy for primary palmar hyperhidrosis. Patients' hyperhidrosis severity, precipitating factors, postoperative complications, surgical results, and satisfaction were assessed. Severity of palmar hyperhidrosis and compensatory hyperhidrosis was classified by two grading scales. RESULTS: The success rate of sympathectomy was 93%. All patients except one suffered from compensatory sweating,which was the main cause of patients' dissatisfaction postoperatively. Seventeen percent of the patients (12 of 72 patients) experienced new symptoms of gustatory sweating (facial sweating associated with eating). Twenty-one patients experienced other complications, including pneumothorax, Horner's syndrome,nasal obstruction, and intercostal neuralgia.

Muliptle organ failure as a consequence of elective sympathectomy

In the post-sympathectomy patient, the abnormalsympathetic skin response may lead to peripheral vascular failureor the reduced cardiac chronotropic response may impair thebody’s capacity to compensate for shock. These may havecontributed to the rapid development of shock and severe multipleorgan dysfunction syndrome in this patient.
He had multiple organ dysfunction syndrome develop, with severerenal and hepatic failure, grade II hepatic encephalopathy,and disseminated intravascular coagulation. He responded remarkablywell to aggressive supportive measures including forced alkalinediuresis, and he was eventually discharged home after 1 month. The patient was previously a healthy, physically fit, nonsmoker.He worked as a body building trainer and led an active, sportylifestyle. The only significant medical history was that hehad received thoracic sympathectomy for axillary hyperhidrosis4 years ago at another hospital.

'Emotional' sweating regulated by neocortex and limbic cortex

Careful observations showed that the forearm sweating responded diversely to various mental stimuli, unlike the palmar sweating whose response was always an increase. Mental arithmetic, mental testing and physical exercise caused an immediate increase in the palmar sweating but often elicited a transient decrease in the forearm sweating, whereas pain, noise, and emotional stimuli consistently provoked an increase of sweating on the forearm as well as on the palm. These observations suggest that the activities of higher centers, presumably involving neocortex and limbic cortex, exert various influences on the central mechanisms of palmar and generalized sweating.

Autonomic dysequilibrium (local sympathectomy) leading to obesity

A similar reduction of fat mobilization from fat depots occurs after VMH lesions, as after local sympathectomy, suggesting that the sympathetic pathway to the adipose tissue runs through the VMH.
Bray and York hypothesize that the change in energy balance in animals after VMH lesions is a result of autonomic dysequilibrium. The sympathetic outflow is reduced and the parasympathetic outflow increased. This shift in balance results in hyperinsulinemia and altered metabolic pathways leading to obesity. During the digestion and metabolism of a meal, the autonomic nervous system provides important (but not sole) feedback control on satiety.

These gustatory phenomena were quite different from physiologic gustatory sweating

In a series of 100 bilateral upper dorsal sympathectomiesperformed for palmar hyperhidrosis, gustatory sweating and othergustatory phenomena were reported by 68 of 93 patients (73%),followed up for an average of 11/2 years. These gustatory phenomenawere quite different from physiologic gustatory sweating: awide range of gustatory stimuli caused a variety of phenomenain varied locations. There was a negative correlation betweenthe incidence of these phenomena and the occurrence of Horner'ssyndrome after sympathectomy. Analysis of our observations,and of clinical and experimental work of others, leads to theconclusion that gustatory phenomena after upper dorsal sympathectomyare the result of preganglionic sympathetic regeneration orcollateral sprouting with aberrant synapses in the superiorcervical ganglion.

Neuroma following nerve injury/surgery

When a nerve is cut, the piece of nerve that is beyond the cut point eventually dies, however, its Schwann cells, the cells that encircle the nerve fibers remain for a much longer time. These Schwann cells secrete a chemical messenger known as nerve growth factor that tells the cut end of nerve where to grow back. So the cut end of nerve will send out multiple sprouts in the direction of the nerve growth factor, however, these sprouts do not go out in an orderly manner, instead they grow out in all directions and eventually cluster and form a knot of nerve fibers. This eventually leads to the formation of a TRUE neuroma or a END BULB or STUMP neuroma.

the primary event of gustatory sweating is a degeneration of the cervical sympathetic neurons

The development of gustatory sweating after cervical sympathectomy can only be explained if one is to admit that the primary event of gustatory sweating is a degeneration of the cervical sympathetic neurons. The initial event is the loss of postganglionic sympathetic neurons and the resulting denervation of the corresponding facial sweat glands. Regeneration of parasympathetic fibers, within the degenerating sympathetic neurilemmal sheets, is a secondary event although it accounts for the observed symptoms.

The four case series were not critically appraised because they are prone to bias and have significant methodological problems. These studies represent level IV evidence according to the NHMRC criteria and one should not draw firm conclusions from their findings.

To date, the benefits or side effects associated with endoscopic thoracic sympathectomy for treating facial blushing have not been properly evaluated and reported.

Further research using a well-designed controlled trial is warranted to assess the efficacy of endoscopic thoracic sympathectomy for treating facial blushing.

We did not identify any controlled trials or cohort studies. The
evidence about effectiveness, based on three case series, was
therefore very limited. The main weakness of these studies was their lack of a comparison group and their resulting inability to exclude a placebo response to surgery. In addition, the methods of assessing outcome were poorly described and not validated, and the range of outcomes assessed was limited. The studies provided very limited evidence that sympathectomy improves blushing. Side effects were common.

The authors found that the incidence of hypotension was a function of the level of sympathetic denervation, occurring in 60% of patients with a T7 sympathectomy, and in 100% of patient with a T4 or higher level of sympathectomy.
(p 226)

"Inappropriate" bradycardia (i.e. "normal" HR in face of ↓MAP with sensory level T3-T4)
Peripheral vasodilation should evoke an ↑ HR. But ↓ venous return → ↑vagal tone, so HR remains at preblock rate but is "inappropriately" slow.

Central neuraxial anesthesia-induced sympathectomy leads to peripheral vasodilation, reduced preload, and subsequently decreased cardiac output. The incidence and extent of hypotension depends on the height of the block, the patient's position, and whether appropriate measures were instituted prophylactically to minimize hypotension.

After thoracoscopic sympathectomy for hyperhidrosis, very severe discomfort and hyperhidrosis in the neighboring non-sympathectomized regions occurred with alarming frequency and intensity.

Permanent thermoregulatory Dysfunction after Sympathectomy

The autonomic dysfunction you see on this thermal image is not a result of the surgery gone wrong, this is the result of a ...successful operation; it is the inevitable consequence of cutting/clamping the sympathetic chain, independently of skill of the surgeon, experience of the surgeon, T2, or T3, T4, or method used. Once the communication is disrupted, (and it happens with the clamping as well), it will disable the body's thermoregulation and will cause malfunctioning of the sympathetic nervous system. This damage is permanent and irreversible. "Sympathectomy is analogous to the act of killing the messenger. The sympathetic nervous system has the critical job of properly controlling and preserving the circulation in different parts of the body, especially in the extremities. By paralyzing the system, the extremity will be more apt to have disturbance of circulation and is left unprotected from fluctuation in circulation. Sympathectomy is similar to permanently removing the central heat and air-conditioning system and never replacing it because of malfunction." H. Hooshamand, MD Neurological Associates, Pain Management Center, Vero Beach, Florida

Sympathectomy reduces DOPAMINE - Latent inhibition and creative drive

Dopamine in the mesolimbic pathway increases general arousal and goal directed behaviors and decreases latent inhibition; all three effects increase the creative drive of idea generation. This has led to a three-factor model of creativity involving the frontal lobes, the temporal lobes, and mesolimbic dopamine.^[34]

This calcification was observed in both feet of 93% of patients, who had
undergone bilateral operation. After unilateral sympathectomy the incidence of calcified arteries on the side of operation was significantly higher than that on the contralateral side (88% versus 18%, p less than 0.01). Although diabetic patients showed longer stretches of calcification than non-diabetic subjects, the difference was not significant in terms of incidence and length. Of 20 patients who had no evidence of calcinosis pre-operatively, 11 developed medial calcification after unilateral operation exclusively on the side of sympathectomy. In seven patients calcinosis was detected in both feet after
bilateral operation. In conclusion, sympathetic denervation is one of the causes of Monckeberg's sclerosis regardless of diabetes mellitus.

Inability to experience/respond to strong emotions - S disrupts signals from the viscera
Reduces/eliminates fear
difficulty concentrating, foggyness, memory affected
lack of motivation/drive/cognitive function - reduction of small vessels in the anterior cingulate cortex, altered catecholamines
overheating due to disabled thermoregulation, even when extreme sweating present - fever in hot weather or with physical activity/brain overheating
difficulty falling asleep/getting up - S eliminates circadian rhythm
Destabilized heart rate, arrythmia, dropped beats, morphofunctional changes in the myocardium
Reduced heart rate = reduced alertness, reduced emotional responses, ('not feeling alive'), all affecting long term memory (encoding).
Suppressed or eliminated Baroreflex = MAP instability
Mean Arterial Pressure instability, reduced short-term haemodynamic variability ('not feeling alive')
Hair loss, loss of eyebrows, eyelashes - altered blood flow in the skin
Dehydrated skin on upper body, face, scalp, - dandruff, skin infections, reduced immune responses
Reduced antibody responses - altered immune system

Several publications/books interchange 'Sympathectomy' and 'Spinal Cord Injury' due to the similarity in presentation/ symptoms.

Sweating after sympathetic surgery is a reflex cycle between the sympathetic system and the anterior portion of the hypothalamus according to our investigations. Reflex sweating will not happen if hand sweating can be stopped without interrupting sympathetic tone to the human brain. (sic!)

GNRH secretion is pulsatile in all vertebrates, and is necessary for correct reproductive function. Thus, a single hormone, GNRH1, controls a complex process of follicular growth, ovulation, and corpus luteum maintenance in the female, and spermatogenesis in the male.

The severity and manifestations of autonomic hyperreflexia are affected by the level of the sympathectomy. With mid-thoracic lesions below the level of cardiac accelerator fibers, hypertension is accompanied by reflex bradycardia transmitted via cardiac accelerator fibers and the vagus. In patients whose sympathectomy is above the level of the thoracic cardiac accelerator fibers, tachycardia may occur because cardiac accelerator fibers become part of the efferent sympathetic activity rather than part of the central inhibitory input from the brain stem and hypothalamus. Arrythmias and occasional heart block may accompany changes in heart rate.
Clinical manifestations of autonomic hyperreflexia include vasodilation, decresed sympathetic activity, and increased vagal activity above the level of the lesion such as nasal congestion, flushing, headache, dyspnea, nausea, and visceral muscle contraction. Vasoconstriction and increased sympathetic activity below the level of the lesion cause vasoconstrictive pallor, sweating, piloerection, and somatic muscle fasciculation. Patients also develop hypertension with headache, blurred vision, myocardial infarction, andretinal, subarachnoid and cerebral hemorrhages that may lead to syncope, convulsion and death.

Sympathectomy has a beta-blocker effect on the healthy patient

Cardiovascular changes after bilateral upper dorsal sympathectomy.

Papa MZ, Bass A, Schneiderman J, Drori Y, Tucker E, Adar R.
"The effect of bilateral upper dorsal sympathectomy (UDS) on cardiac function was investigated in two groups of young healthy patients who underwent bilateral excision of T2 and T3 ganglia for palmar hyperhidrosis.
The mean pulse rate decreased significantly in patients after they underwent bilateral UDS.
Pulse rates taken at rest and after effort were significantly lower than those taken after operation, and the blood pressure response to exercise was blunted. ECG tracings showed a significant change in the electrical frontal plane axis and shortening of
the QTc interval. These changes were evident 30 days after operation and persisted for 2 years. In conclusion, bilateral UDS has no overt arrhythmogenic effect in the young, healthy heart and its beta-blocker-like effect persists for at least 2 years." (the time of the tests performed)

Beta blockers block the action of endogenous catecholamines (epinephrine (adrenaline) and norepinephrine (noradrenaline) in particular), on β-adrenergic receptors, part of the sympathetic nervous system which mediates the fight or flight response.

The increase in heart rate in response to HUT (head-up tilt) was significantly reduced after surgery in the ETS group (from 34 ± 18 to 14 ± 11 beats·min⁻¹). Orthostatic hypertension disappeared completely after ETS , whereas the prevalence of orthostatic hypotension increased significantly after ETS (from 3 of 11 to 9 of 11 patients). http://www.springerlink.com/content/dk8tq89wnhq4naqy/

Cardiac arrest - a major complication of bilateral sympathectomy

Thoracic sympathectomy has usually minimal consequences if unilateral, especially on the right side. For
bilateral procedures, a mean reduction of the heart rate of 12% was reported. Around 50% of patients have bradycardia in the following minutes of abilateral surgery and mean and diastolic blood pressures significantly reduced.
Since the sympathectomy will block the chronotropic response, a significant increase of the ejection volume is observed when the patient moves in the erect position from dorsal decubitus.

Chronotropic incompetence, an attenuated heart rate response to exercise, is a predictor of all-cause mortality in healthy populations. This association may be independent of exercise-induced myocardial perfusion defects.

After sympathectomy, BP is maintained at nearly normal levels mainly through activation of the renin angiotensin system.

Heart and Circulatory Physiology, Vol 259, Issue 5 1337-H1342, Copyright © 1990 by American Physiological Society

Angiotensin receptor blockers reduce the frequency of atrial fibrillation and stroke. Renin-angiotensin system blockade delays or avoids the onset of type 2 diabetes and prevents cardiovascular and renal events in diabetic patients. Thus, blockade of this system will remain a cornerstone of our strategies to reduce cardiovascular risk.

Renin-angiotensin system and cardiovascular risk

Schmieder RE, Hilgers KF, Schlaich MP, Schmidt BM.

A patient with angina pectoris who had been successfully treated by thoracoscopic cardiac sympathectomy was scheduled to have scalp debridement under general anaesthesia for a scald burn. There were haemodynamic changes during and after the operation including anaesthetic induction, endotracheal intubation, maintenance, and early recovery period. The sympathetic denervated heart showed little chronotropic response to anaesthetic and surgical stimulation. On the contrary, the parasympathetic response was predominant. An episode of severe bradycardia occurred during endotracheal suctioning prior to extubation. The haemodynamic response to cardiac sympathetic denervation corresponded to the efferent effect of beta-receptor blockade.

Sympathectomy-induced alterations of immunity

Many studies have demonstrated that ablation of the sympathetic nervous system (SNS) alters subsequent immune responses. Researchers have presumed that the altered immune responses are predominantly the result of the peripheral phenomenon of denervation.
Activation of the CNS was determined by immunocytochemical visualization of Fos protein in brains from male C57BL/6 mice at 8, 24, and 48 h following denervation. A dramatic induction of Fos protein was found in the paraventricular nucleus (PVN) of the hypothalamus and other specific brain regions at 8 and 24 h compared to vehicle control mice. Dual-antigen labeling demonstrates that corticotrophin releasing factor (CRF)-containing neurons in the PVN are activated by chemical sympathectomy; however, neurons containing neurotransmitters which may modulate CRF neurons, such as vasopressin, tyrosine hydroxylase, and adrenocorticotropin, do not coexpress Fos. Our findings suggest an involvement of the CNS in sympathectomy-induced alterations of immunity.

Marked MAP instability following sympathectomy

In conclusion, the results of the present study suggest a major role for the sympathetic nervous system in the regulation of regional circulations, the loss of which in sympathectomized rats results in a marked instability of MAP (mean arterial pressure). The vasodilator component of MAP lability after sympathectomy does not appear to depend on an episodic release of NO synthesized by the L-arginine pathway.

These results indicate that chronic surgical sympathectomy of the heart can be successfully accomplished in the rat and guinea pig. Such sympathectomy induces a postjunctional supersensitivity in guinea- pig right atria which is qualitatively and quantitatively similar to that described previously for chronic treatment with reserpine. Bilateral surgical sympathectomy provides a valuable tool for future investigations of the cellular basis of supersensitivity in the myocardium.

What is ETS or Sympathectomy?

If you do a quick search on google because you want to find a solution for your sweaty palms, or do not want to blush every time someone looks at you, you will be flooded by all the information from the surgeons offering this procedure. If you only read these and do not have a medical background, you might fall for their statements and think to yourself: well, isn't medical science wonderful?!
You make your booking with one of the surgeons who will charm you and soon you are being wheeled in for the surgery with the promise from the surgeon, that it will change your life. You don't even know how true that is, until you wake up.
Here you will find the other side of the sales pitch and some answers to just how your life will never be the same.

Sympathectomy supressed baroreflex control of heart rate

Loss of Baroreflex = aberrant blood pressure

Reduced baroreflex sensitivity is associated with increased vascular calcification and arterial stiffness

The reduction in BRS and the resulting aberrant blood pressure response to the physiological stress and volume changes of HD may be important in the further understanding of the pathophysiology of the increased mortality in HD patients with vascular calcification.

Visceral Functions of the Nervous System

B A McSwiney

Sympathectomy can be considered a psychiatric surgery

ETS can alter many bodily functions, including sweating, heart rate, heart stroke volume, blood pressure, thyroid, baroreflex, lung volume, pupil dilation, skin temperature, goose bumps and other aspects of the autonomic nervous system. It can diminish the body's physical reaction to exercise and/or strong emotion, and thus is considered psychiatric surgery. In rare cases sexual function or digestion may be modified as well.

Circadian Rhythm eliminated by Sympathectomy

The abrupt increase and decrease in BP observed at the time when the lighting conditions are changed are eliminated by chemical sympathectomy

The disruption of the baroreflex selectively eliminatesthe circadian rhythm of BP, and the circadian rhythms of BP andHR are modulated by the autonomic nervous system in rats. The circadianrhythms of BP and HR are regulated by different mechanisms involvingthe autonomic nervous system.

Individual cardiovascular response to different levels of sympathetic blockade varies widely, depending on the degree of sympathetic tone before the block.
High TEA added to general anaesthesia significantly decreased the cardiac acceleration in response to decreasing blood pressure, suggesting that baroreflex-mediated heart rate response to a decrease in arterial blood pressure depends on the integrity of the sympathetic nervous system.

Changes in Electrophysiology following sympathectomy

Sympathectomised dogs presented significant increases in: basic sinus period, sino-atrial conduction time (SACT), AH and HV intervals of the His bundle electrogram, atrial functional (AFRP) and effective (AERP) refractory periods, atrio-ventricular node functional (AVNFRP) and effective (AVNERP) refractory periods, ventricular functional (VFRP) and effective (EVRP) refractory periods and atrial (AMAP) and ventricular (VMAP) monophasic action potential durations. Corrected sinus recovery time (CSRT) was not affected by chemical sympathectomy. Neither was the atrial ERP/MAP duration ratio. This new form of sympathectomy affects all the levels of the cardiac conduction system. Such results are in accordance with those obtained with surgical sympathectomy or the use of beta-blocking agents.

retarded adaptation of hemodynamics to a sudden start of exercise following sympathectomy

The exercise capacity and the increase of coronary and systemic hemodynamics under treadmill exercise were studied in 5 dogs, chemically sympathectomized with 6-hydroxy-dopamine.

Completeness of adrenergic denervation was verified by stimulation of the right stellate ganglion, by intravenous administration of tyramine, and by demonstration of supersensitivity to exogenous norepinephrine.

These dogs demonstrated a retarded adaptation of hemodynamics to a sudden start of exercise. A fall in mean arterial pressure below 45 mmHg within 10 to 15 sec lead to collapse.
steady state attainment of hemodynamic parameters was considerably delayed.

Denervation supersensitivity leads to Raynaud's Disease

Cannon and his colleagues showed in the 1930s that section and subsequent degeneration of the sympathetic nerves led to a marked supersensitivity of the sturcture to exogenous catecholamines. The increase in sensitivity ranged from 10-to 100-fold in different tissues, such as the spleen on section of the splenic nerves, or the nictitating membrane on section of the postganglionic cervical sympathetic nerve or the heart on removal of the stellate ganglion. In smooth muscle the increase in sensitivity is mostly explained by the associated loss of neuronal re-uptake of noradrenaline, with only a lesser role for the increase in receptor numbers.

Changes in Electrophysiology following sympathectomy

Cardiovascular collapse caused by carbon dioxide insufflation during sympathectomy

Carbon dioxide insufflation into the pleural space during one-lung anaesthesia for thoracoscopic surgery is used in some centres to improve surgical access, even though this practice has been associated with well-described cardiovascular compromise. The present report is of a 35-year-old woman undergoing thoracoscopic left dorsal sympathectomy for hyperhidrosis. During one-lung anaesthesia the insufflation of carbon dioxide into the non-ventilated hemithorax for approximately 60 seconds, using a pressure-limited gas inflow, was accompanied by profound bradycardia and hypotension that resolved promptly with the release of the gas.

Sympathetic regulation of the cerebral circulation by the carotid chemoreceptor reflex

After bilateral cervical sympathectomy (n = 9), carotid chemoreceptor reflex stimulation induced significantly different (P less than 0.01) effects on cerebral blood flow, which rose by 42 +/- 8%, and cerebral vascular resistance, which did not change.
In "sham" dogs, the repeat response to carotid chemoreceptor stimulation also induced significantly different effects from those in dogs with sympathectomy. Thus, in the conscious dog, stimulation of the carotid chemoreceptor reflex elicits significant sympathetically mediated vasoconstriction in cerebral vessels.

Effect of adrenalectomy or sympathectomy on spinal cord blood flow

We conclude that adrenalectomy near-totally ablates the hypothermia-associated increase in RSCBF (regional spinal cord blood flow) measured in intact rats and that abdominal sympathectomy totally ablates it. This evidence complements morphological evidence for adrenergic innervation of the spinal cord vasculature.

Objective: Previous studies indicate that the adrenal gland plays a compensatory role in the maintenance of blood pressure in chemically sympathectomized rats. However, the mechanisms responsible for compensatory adrenal responses are poorly understood. This study examined the regulation of adrenal growth and type 1A, 1B, and type 2 angiotensin II (Ang II) receptor (AT1A, AT1B and AT2) expression in the adrenal gland induced by sympathectomy.

Definition of the sympathetic ganglionic chain, that is cut/clamped during surgery

sympathetic ganglionic chain

From: A Dictionary of Psychology | Date: 2001 | Author: ANDREW M. COLMAN

sympathetic ganglionic chain n. A string of ganglia running down each side of the spinal cord throughout most of its length, containing cell bodies of neurons that belong to the sympathetic nervous system and that project axons to muscles and glands, controlling the smooth muscles of the blood vessels, eyelids, hair follicles, sweat, tear, and salivary glands, respiratory organs, irises, and also the heart and other organs. Also called the chain ganglia or sympathetic trunk.[From Greek syn with + pathos suffering + ganglion a cystic tumour]

Severe Hyperhidrosis as a side effect of ETS surgery to treat Palmar Hyperhidrosis...

Another example of the thermoregulatory dysfunction. However the whole body Hyperhidrosis is much more difficult to live with or cover up, as it soaks through clothes within minutes. The true number of people having disabling full body HH after this surgery is unknown. Surgeons maintain that it is a minute percentage of people. However there are too many who request reversals due to this side-effect. In fact the controversial reversal surgeries have become a very profitable part of the ETS surgeries. There are surgoens who specialize in doing reversals only. ETS is often covered by health insurance. Reversals are not. Surgeons and medical professionals NOT involved with the surgery maintain that the damage to the sympathetic chain can not be repaired. This applies to the clamping method as well. In that case the clamps would have to be removed within 24 hours. Usually it takes longer for the full body Hyperhidrosis to appear.

Thermoregulatory Disfuction - Severe CS. One of many of the side-effects of the elective surgery.

Note sharp line on upper chest: upper part of shoulders, neck, head and arms: anhidrosis, the inability to sweat and dissipate heat. 40% of the body heat exits the body through the top of the head. This aspect of the thermoregulation is disabled. Below the line of the T2 cut: PATHOLOGICAL sweating that requires complete change of clothes several times during the day. Sweating is not limited to the chest but includes full body surface. Constant wet skin is vulnerable to various skin diseases. CS is not only thermoregulatory. It can be triggered by stress, even in cold/winter conditons! This is the result for a patient who underwent the elective cosmetic surgery - that is hailed a a gold standard for palmar HH treatment. And this is only one side-effect of the many that are the necessary consequence of disrupting the sympathetic chain, irrespective of the surgeon's expertise or experience in executing the procedure. Post ETS sweating can not be predicted. Sweating patterns prior to surgery is not an indication of the CS post surgery. There is no difference in gender or weight when it comes to CS.

Nerve regeneration aka nerve sprouting leads to abnormal nerve function and pathological conditions

Regenerating sympathetic fibers create connections with nociceptive C-fibres, causing abnormal, sympathetically maintained pain conditions. Clinical studies in humans support the idea that nociceptors develop catecholamine sensitivity after complete or partial nerve lesions.
Sympathectomy, denervation has been linked to the development of Reflex Regional Pain Syndrome.
The regeneration of the sympathetic fibers is also responsible for the abnormal sweating during eating or smelling (food). This reaction can be triggered by any taste or smell, including spicy or hot food, apples, anything sour, chocolate, sweets etc. For the post-sympathectomy patient the otherwise anhydriotic areas of the face, upper body and arms will react with abnormal sweating and chills to these flavors/smells. The condition is called Frey's Syndrome and is caused by abnormal connections/interactions between the salivary gland and the sprouting sympathetic fibers.

Immune response and sympathectomy

Bone remodeling and resorption

The results further support that a regional sympathectomy causes qualitative alterations in bone modeling and remodeling, leading to bone resorption.

Worth considering:

If you damage your sympathetic nerve/chain - let's say - in a car accident, it it treated as a 'damage' and the symptoms that necessarily follow: 'illness'. You will - if lucky - have a diagnosis - most likely dysautonomia, the same condition (with numberless symptoms) people with spinal cord injuries suffer from. The imbalance between the (now disabled) sympathetic and parasympathetic nervous system will be responsible for the body's malfunctioning - physically and emotionally. So how can the same, destructive, surgical procedure be called CURE for people with non-life threating conditions, such as facial blushing, palmar or axillary sweating? And how can doctors, well aware of the impact the surgery will have, offer the surgery? When did the wellbeing of the patient become an obsolete aim?
This truly defies reason.

Patients with hyperhidrosis of the palm or soles, who fail to respond to topical agents, deserve a trial of conservative therapy, botulinum toxin, or iontophoresis, before aggressive surgical techniques that carry with them the risk of lifelong troublesome side effects are offered.
