"Sympathectomy is a technique about which we have limited knowledge, applied to disorders about which we have little understanding." Associate Professor Robert Boas, Faculty of Pain Medicine of the Australasian College of Anaesthetists and the Royal College of Anaesthetists, The Journal of Pain, Vol 1, No 4 (Winter), 2000: pp 258-260
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.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

Abstract
Background: The purpose of this study was to evaluate the long-term and midterm effects of thoracic sympathectomy on pulmonary function and to assess the influence of the sympathetic nervous system on bronchomotor tone.
We conclude that thoracic sympathectomy generates a mild, although significant, impairment of the bronchomotor tone.
sympathectomy leads to qualitative alterations in localized bone modeling and remodeling
Disruption of the control of modeling within the temporal bone may lead to various bone diseases such as otosclerosis, osteogenesis imperfecta, Paget's disease of bone, fibrous dysplasia, or the erosion of bone associated with chronic otitis media.

Sympathectomy Suppresses Baroreflex Control of Heart Rate
ETS significantly altered baroreflex in both pressor and depressor tests in all patients. Baroreflex was completely suppressed in 1 of 19 patients in the pressor test and in 9 of 21 patients in the depressor test. We conclude that baroreflex responses are suppressed in patients who receive ETS.

To evaluate the effects of acute sympathetic denervation on the baroreflex control of heart rate, baroreflex sensitivities were compared in lightly anesthetized humans who had either cervical (N = 20) or lumbar epidural anesthesia (N = 18). The results suggest that cardiac sympathectomy induced by epidural anesthesia can suppress partially baroreceptor function by interrupting sympathetic efferent fibers innervating the heart during high levels of epidural anesthesia, but that lumbar sympathectomy during epidural anesthesia is unlikely to affect baroreceptor activity.

sympathectomy-induced adrenal hypertrophy
Conclusions: Impairment of the sympathetic nervous system with guanethidine withdraws the normal stimulation of this system on the circulating renin-angiotensin system, but upregulates the expression of adrenal Ang II receptors. Increased expression of adrenal AT2 and AT1A receptors may play an important role in adaptive adrenal hypertrophy and hormonal responses to sympathectomy.

Interruption of sensory fibres
| Cutaneous innervation in man before and after lumbar sympathectomy: evidence for interruption of both sensory and vasomotor nerve fibres. | ||
Coventry BJ, Walsh JA Department of Surgery, University of Adelaide, Royal Adelaide Hospital, Adelaide, South Australia 5000, Australia. | ||
BACKGROUND: Rest pain and severe ischaemia in patients who are unable to be offered (further) surgery to revascularize the lower limb is still problematic. Lumbar sympathectomy has been used for many years but the mechanisms by which this works are not absolutely clear. Both sensory and vasomotor fibres travel in the lumbar sympathetic chain and the effects of lumbar sympathectomy on these nerve types have been investigated in the present paper. METHODS: Immunohistochemical methods were used to detect neuropeptides contained in sensory and vasomotor nerves in the lower limb skin of (i) patients having amputations for peripheral vascular disease (PVD) after previous (chemical or surgical) sympathectomy; (ii) patients having amputations for PVD without previous (chemical or surgical) sympathectomy; and in control normal skin. The three groups are compared and the results are discussed. RESULTS: Normal and PVD controls had intact sensory and vasomotor nerves around dermal cutaneous blood vessels, but these were completely or virtually completely lost after lumbar sympathectomy, by either chemical or surgical means. CONCLUSIONS: Lumbar sympathectomy severs both vasomotor and sensory fibres, suggesting that relief of rest pain may be explained not only by increased cutaneous and muscle blood flow, but also by nociceptive sensory denervation.

U.S. Government Studies the Neurocardiologic Dysfunction of Sympathectomy Patients
I participated in the study in November, 2004. For five days I underwent a battery of tests, including PET scans, drug tests, sweat tests, a tilt-table test, EKG, and a lumbar puncture (spinal tap). Conclusions:
1. Partial cardiac denervation as a result of bilateral thoracic sympathectomies.
2. Complete absence of blood vessel constriction in the arms, as expected in thoracic sympathectomy.
3. Complete loss of sympathetic innervation to the thyroid.
4. Abnormal catecholamine levels in the spinal fluid.
Bear in mind that these researchers are only looking at a few of the many aspects of ETS dysfunction.

16% of our hospitalised patients will suffer a significant adverse event which is totally unrelated to their original medical condition . This translates as 1 patient in 6 , which is four times the reported occurrence of medical error incidents in the United States , and a full 6% higher than Britain's 10% error rate .
18 , 000 Australian patients die each year as a direct result of avoidable injuries and complications inflicted from withn our health system environments .
Another 50 , 000 Australian patients per year are left with permanent disabilities , and hundreds of thousands more are avoidably injured to some greater or lesser degree .
80 , 000 Australian patients per year are hospitalised due to medication errors , syphoning a massive $350m from the Federal Health Budget annually .
And these figures do not take into account the recognised errors which take place in other clinical outpatient settings such as GP surgeries , radiology suites , and other outpatient clinics where the error rate has been found to be at 23% in one Sydney study .

Dopamine-
- hydroxylase is an enzyme that is localized to catecholamine-containing vesicles in sympathetic nerves and the adrenal medulla, and is also found in the serum. Treatment of rats with 6-hydroxydopamine, a drug which destroys sympathetic nerve terminals, leads to a decrease in serum dopamine-
-hydroxylase activity. The decrease is not due to an effect on the adrenal medulla or to an increase in circulating inhibitor or inhibitors of enzyme. These data represent evidence that at least a portion of the circulating dopamine-
-hydroxylase activity arises from sympathetic nerve terminals.

ROLE OF ASERNIP-s: monitoring
approval process should decide the type of monitoring to be undertaken.
• As a minimum, audits of indications and outcomes should be done.
• Access to reliable surgical data (local and global), organised in such a
way that performance comparisons can be made.
• It is highly desirable to coordinate and standardise any study designs,
e.g. outcomes measured in the same way for case series and audits
across hospital services or as done in previous studies.
If an audit or controlled clinical study is being contemplated, consider
whether this can be done as part of a multi-centre study.
• Develop/amend internal processes for the reporting of any adverse
events from new procedures and consider external processes e.g. as
part of multicentre audits or advising the Therapeutic Goods Authority
or the New Zealand New Technology Committee re problems with
devices.
THE Australian Story - ASERNIP-s ROLE
Most techniques new to Australia and New Zealand will have been evaluated
or at least implemented elsewhere in the world first. Issues that should be
considered include:
• Has the technique been previously evaluated?
Hospitals/health services should establish whether an assessment has
already been done through international or national systematic review
or Health Technology Assessment (e.g. INAHTA– International
Network of Agencies for health technology assessment, ASERNIP-S –
Australian Safety and Efficacy Register of New Interventional
Procedures - Surgical, Cochrane Collaboration, MSAC – Medical
Services Advisory Committee), clinical studies, industry reports,
laboratory testing or animal studies, reports of case series overseas,
reports of experiences of the techniques in Australian and New
Zealand facilities (see Appendix 1 for a list of relevant organisations
and their web-sites).
• How reliable is the evaluation?
Interpretation of assessments should include the likely robustness of
the evidence e.g. type of study design, were studies large enough to
show reliable results for morbidity and mortality; were there possible
confounding factors, such as the age of patients?
THE Australian Story - MSAC version
- provided by a medical practitioner, and
- a clinically relevant service (generally accepted in the medical profession as being necessary for the appropriate treatment of the patient).
Medicare item 35003 relates to the performance of cervical or upper thoracic sympathectomy by any surgical approach (irrespective of whether it is conducted by open exposure or endoscopically). Sympathectomy has been listed on the MBS for over three decades, and permitted by any surgical approach since 1991.
The Medical Services Advisory Committee (MSAC) was established in 1998 to advise the Minister for Health and Ageing on the strength of evidence pertaining to new and emerging medical technologies and procedures in relation to their safety, effectiveness and cost-effectiveness and under what circumstances public funding should be supported. MSAC has never considered this procedure, as it was listed on the MBS prior to MSAC's formation, and is therefore not a 'new and emerging medical technology'.
The Government relies on the advice of the medical profession in relation to the clinical relevance of procedures already listed on the MBS. If the Royal Australasian College of Surgeons were to formally advise the Government that it no longer regards this procedure as being clinically relevant, the Government would take appropriate action in relation to the MBS.

Unstable blood pressure after sympathectomy
Risks
Side effects of sympathectomy may include decreased blood pressure while standing, which may cause fainting spells. After sympathectomy in men, semen is sometimes ejaculated into the bladder, which may impair fertility. After a sympathectomy done by inserting an endoscope in the chest cavity, patients may experience chest pain with deep breathing. This problem usually disappears within two weeks. They may also experience pneumothorax (air in the chest cavity).

Australian Story 3!
TIMBO McCarty, an Australian/New Zealander who has been suffering from the side-effects of ETS for eight years and has been working on this website alongside me as well as helping organise meetings, had enough of the side-effects and committed suicide on October 29 at the age of 45. His Father and Mother asked me to put this on the website and to let everyone know that he had had enough. Timbo was always there for me as a friend to talk when I felt everything was getting to me. Timbo was also was a fighter. He wanted ETS surgery to be stopped and was depressed that the surgery is still being performed routinely. He was aghast that his surgeon, Dr Lin in Taiwan, who performed ESB (clamping of the T2 nerve), removed his clamps at a fee yet still performed reversals routinely even though so many people have come forward with complaints.....
This is the second suicide in two years from people who have had terrible side-effects.

| Endoscopic thoracic sympathectomy (ETS) has come into widespread use for palmar hyperhidrosis. Side sffects after ETS was widely discussed in Taiwan society in the past few months. Lots of people in Taiwan suffer from hyperhidrosis palmaris. ETS is covered by the National Health Insurance, and patient billing for this operation does not exceed US$ 60. This is why this operation is so popular here 1 . Patients with severe compensatory sweating after ETS must change clothes several times a day (some patients complained that they change as often as 10 times a day), resulting in serious impact on work and social interaction. Patients suffering from such serious side effects in Taiwan have formed a support group based on an Internet discussion forum to request the government to take this problem seriously. Starting in October 2004, The Department of Health, Executive Yuan, Taiwan, has prohibited surgeons from performing this operation on patients under 20 years old. To our knowledge, this type of support group also exists in United States, England, Sweden, Spain and Japan (Table 1). ETS is a relatively safe and simple procedure. However the side effects are possibly devastating 2 . All physicians providing this service and all peoples preparing to undergo this treatment should know this well. | |||

| Abstract |
Changes in the patterns of production and in the effects of signal substances may be involved in the development of tendinosis, a chronic condition of pain in human tendons. There is no previous information concerning the patterns of sympathetic innervation in the human patellar tendon. In this study, biopsies of normal and tendinosis patellar tendons were investigated with immunohistochemical methods, including the use of antibodies against tyrosine hydroxylase (TH) and neuropeptide Y, and against 1-, 2A-, and 1-adrenoreceptors. It was noticed that most of the sympathetic innervation was detected in the walls of the blood vessels entering the tendon through the paratendinous tissue, and that the tendon tissue proper of the normal and tendinosis tendons was very scarcely innervated. Immunoreactions for adrenergic receptors were noticed in nerve fascicles containing both sensory and sympathetic nerve fibers. High levels of these receptors were also detected in the blood vessel walls; 1-adrenoreceptor immunoreactions being clearly more pronounced in the tendinosis tendons than in the tendons of controls. Interestingly, immunoreactions for adrenergic receptors and TH were noted for the tendon cells (tenocytes), especially in tendinosis tendons. The findings give a morphological correlate for the occurrence of sympathetically mediated effects in the patellar tendon and autocrine/paracrine catecholamine mechanisms for the tenocytes, particularly, in tendinosis. The observation of adrenergic receptors on tenocytes is interesting, as stimulation of these receptors can lead to cell proliferation, degeneration, and apoptosis, events which are all known to occur in tendinosis. Furthermore, the results imply that a possible source of catecholamine production might be the tenocytes themselves. Microsc. Res. Tech., 2007. © 2007 Wiley-Liss, Inc. |

Sympathetic innervation of white adipose tissue and its regulation of fat cell number.
Molecular and Cellular Biology and Pathobiology Program, Medical University of South Carolina, Charleston, South Carolina 29425, USA.
White adipose tissue (WAT) is innervated by the sympathetic nervous system (SNS), and the central origins of this innervation have been demonstrated for inguinal and epididymal WAT (iWAT and eWAT, respectively) using a viral transneuronal tract tracer, the pseudorabies virus (PRV). Although the more established role of this sympathetic innervation of WAT is as a major stimulator of lipid mobilization, this innervation also inhibits WAT fat cell number (FCN); thus, local denervation of WAT leads to marked increases in WAT mass and FCN. The purpose of this study was to extend our understanding of the SNS regulation of FCN using neuroanatomical and functional analyses. Therefore, we injected PRV into retroperitoneal WAT (rWAT) to compare the SNS outflow to this pad from what already is known for iWAT and eWAT. In addition, we tested the ability of local unilateral denervation of rWAT or iWAT to promote increases in WAT mass and FCN vs. their contralateral neurally intact counterparts. Although the overall pattern of innervation was more similar than different for rWAT vs. iWAT or eWAT, its SNS outflow appeared to involve more neurons in the suprachiasmatic and solitary tract nuclei. Denervation produced significant increases in WAT mass and FCN for both iWAT and rWAT, but FCN was increased significantly more in iWAT than in rWAT. These data suggest differences in origins of the sympathetic outflow to WAT and functional differences in the WAT SNS innervation that could contribute to the differential propensity for fat cell proliferation across WAT depots in vivo.

...whereas sympathectomy abolishes the
vasoconstrictor reaction, indicating that it is mediated by a local sympathetic axon
reflex.
Extraneous agents, such as large doses of alcohol and morphine, cause increased
lipolysis. This action can be blocked by chemical sympathectomy and is believed to be
due to stimulation of the sympathetic system within the central nervous system.9
Thus the control of metabolism in white fat is complex and dependent on many factors,
both within the adipocytes themselves and in the organism as a whole.
Total chemical sympathectomy in experimental
animals results in loss of shivering and nonshivering thermogenesis, and death within a
few hours.9
Since the effects of sympathectomy on the denervated
area are profound with increased blood flow and warmth and decreased sweating, it is
possible that pain relief is secondary to these phenomena without requiring any sort of
aberrant neural conduction.
This has occurred after stellate ganglion
block37 and lumbar sympathectomy.38 McCallurn and Glynn37 propose that increased
activity in the sympathetic nerves as the effects of the anesthetic block lessen cause
pain, particularly in circumstances where there was abnormal sympathetic activity
before the procedure (such as sympathetic dystrophy). This type of pain is often
resistant to opioid analgesics but may respond well to transcutaneous nerve stimulation.
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.71
These hypothalamic control areas are themselves sensitive to feedback mechanisms.

Australian Story2 (rant)
"I do realise there are sweat tests conducted after a reversal but my point is that doctors do not do these tests on ETS patients. Therefore how can they generalise and say that after ETS CS will be mild or severe?? They do not do follow ups on ETS patients and if a patient complains of heavy CS the doctor may see it as mild and normal CS for statistical purposes."
http://etsandreversals.yuku.com/topic/3016/t/Eastern-Surgical-Australia.html
My question is: did anybody ever made an attempt at quantifying the scale of the 'compensatory sweating" after the surgery? Is there an attempt made to measure the amount of sweating before and after the surgery? Surely not, it would provide the proof that Sympathectomy causes profound sweating. What else could be the reason for not measuring this very significant side-effect? And then, - based on what!!!? - are the surgeons making the sweeping statements about the % of the people and the severity or scale of sweating after the surgery? Or about patient satisfaction rates??? How are these figures made up? Surely nobody bothered to ask any questions from me...
Why are the surgeons not accountable by providing statistical information on the side-effects after the surgery??? Don't they want to know how effective their surgery is? If it is safe ?! Reliable? Does more good then harm???
My surgeon did not schedule a follow up consultation. If I would have not called him (which I almost didn't), he would have never been told about the side-effects I have experienced. Did he file a report on my condition/case? Of course not. It would harm the statistics. (What statistics?!)
Slowly the surgeons admit to more and more side-effects
"Another clinical observation which will need more time for verification is the thought that the higher failure rate of sympathectomy when ETS is done only for facial blushing has to do with the fact that when the sympathectomies were done in the past for vascular problems the success rate was very minimal. At this time we know that higher failure rate was due to a clinical situation which we call denervation hypersensitivity. In essense the blood vessels become very sensitive to certain circulating hormones within the blood system. Dr. Reisfeld believes that the same phenomenon happens in this facial blushing presentation. More time and more clinical experience is needed before there can be a more definite conclusion."
Hopefully this may assist court cases but it sounds like Reisfeld is trying to cover his legal liability in his "at the time we thought..." comments.
Also see how the Australian site www.easternsurgical.com.au (click on blushing) have now admitted "some failures" and had to remove their biased comments about 500 consecutive successes.
Unfortunately the more people who have ETS side effects, the more the statistics become 'significant' to such doctors.

Norepinephrine Turnover - increase in plasma NE=increase in brain NE
Norepinephrine Turnover Is Increased in Suprabulbar Subcortical Brain Regions and Is Related to Whole-Body Sympathetic Activity in Human Heart Failure
From the Baker Medical Research Institute, Melbourne, Australia.

This study, for the first time, demonstrates elevated suprabulbar subcortical noradrenergic activity in human CHF and identifies a positive correlation between this and the level of whole-body NE spillover. The findings suggest that the activation of noradrenergic neurons projecting rostrally from the brain stem mediates sympathetic nervous stimulation in CHF.
cerebrovascular CO2 reactivity

Effects of intraventricular 6-hydroxydopamine on cerebrovascular CO2 reactivity in anesthetized rats.
Regional cerebral blood flow was measured by the 14C-ethanol technique in anesthetized rats before and after intraventricular injection of 6-hydroxydopamine. This treatment reduced the fluorescence of the central noradrenaline and dopamine nerve terminals, as well as of the perivascular nerve terminals in cerebral vessels. The administration of 6-hydroxydopamine had no significant effect on cerebral blood flow at normocapnia. The cerebrovascular reactivity to hypercapnia was significantly increased in the 6-hydroxydopamine treated animals. The results indicate an involvement of central catecholamine pathways in the cerebrovascular reactivity to hypercapnia.

catecholamine neuron in cerebral circulation
J Neurosurg. 1986 Sep;65(3):370-5
A role of the central catecholamine neuron in cerebral circulation.
The effect of the central catecholaminergic neurons on the cerebral microcirculation was investigated by means of a unilateral intracerebral injection of 6-hydroxydopamine (6-OHDA) which produced the degeneration of catecholamine (CA) nerve terminals. Subsequent observation with CA histofluorescence revealed an absence of CA fibers in the vicinity of the 6-OHDA injection site. A significant increase in regional cerebral blood flow (rCBF), measured by the hydrogen clearance method, was demonstrated in the CA-depleted cortex under normocapnia as compared with rCBF in the control cortex (CA-depleted cortex 47.0 +/- 2.8 ml/100 gm/min; control cortex 38.5 +/- 3.5 ml/100 gm/min; p less than 0.005). The increased rCBF in the cortex treated with 6-OHDA was suppressed by the iontophoretic replacement of noradrenaline (NA) to the CA-depleted cortex. An iontophoretic replacement of 10(-5) M dopamine (DA) mildly suppressed the increased rCBF in the 6-OHDA-treated cortex. The CO2 reactivity in the CA-depleted cortex was significantly lower than that of the control cortex (CA-depleted cortex 2.13% +/- 0.6%/mm Hg; control cortex 3.53% +/- 0.70%/mm Hg). No change was noticeable in the cerebral glucose metabolism in the CA-depleted cortex in an investigation based on tritiated (3H)-deoxyglucose uptake. It is suggested that the 6-OHDA-induced change in cerebral blood flow (CBF) is not secondary to alterations in cerebral metabolic rate, and that the central NA neuron system innervating intraparenchymal blood vessels regulates CBF through a direct vasoconstrictive effect on the cerebral blood vessels. The central DA neuron system may modulate the cerebral circulation as a mild vasoconstrictor.

A role for the ventral surface of the medulla
in regulation of nasal resistance
M. A. Haxhiu, K. P. Strohl, M. P. Norcia, E. van Lunteren,
E. C. Deal Jr and N. S. Cherniack
Nasal resistance is known to be affected by changes in nasal blood volume
and hence to depend on sympathetic discharge to nasal blood vessels.
Structures located superficially near the ventrolateral surface of the medulla
significantly affect respiratory and sympathetic activity and the tone of the
trachea. To assess the importance of these structures on nasal patency, we
measured transnasal pressure at a constant flow and examined the change in
pressure produced by topically applied N-methyl-D-aspartic acid (NMDA).
Experiments were performed in chloralose-anesthetized, paralyzed, and
artificially ventilated cats. NMDA administered on the intermediate area of
the ventral surface of the medulla decreased transnasal pressure and increased phrenic nerve activity. The response to
NMDA could be diminished or abolished by application to the ventral medullary surface of the NMDA antagonist
2-amino-5-phosphonovalerate (2-APV) or the local anesthetic lidocaine. Carotid sinus denervation and
posthypothalamic decerebration did not alter the nasal and phrenic nerve responses to NMDA; however, cervical
sympathetic denervation decreased these responses, both in intact and in bilaterally adrenalectomized animals. Therefore,
activation of NMDA receptors on structures near the ventral surface of the medulla increases tone in the nasal
vasculature and leads to a response pattern that includes changes in not only phrenic nerve activity and blood pressure
but also nasal patency.
Noradrenaline (NA) has been shown to influence astrocytic and vascular functions related to brain homeostasis
doi:10.1097/00004647-199708000-00008
Astroglial and Vascular Interactions of Noradrenaline Terminals
in the Rat Cerebral Cortex
Noradrenaline (NA) has been shown to influence astrocytic and vascular functions related
to brain homeostasis, metabolism, local blood flow, and blood-brain barrier permeability.
In the current study, we investigate the possible associations that exist between
NA-immunoreactive nerve terminals and astrocytes and intraparenchymal blood vessels
in the rat frontoparietal cortex, both at the light and electron microscopic levels. As a
second step, we sought to determine whether the NA innervation around intracortical
microvessels arises from peripheral or central structures by means of injections of
N-(2-chloroethyl-N-ethyl-2-bromobenzylamine) (DSP-4), a neurotoxin that specifically
destroys NA neurons from the locus ceruleus. At the light microscopic level, 6.8% of all
NA-immunoreactive nerve terminals in the frontoparietal cortex were associated with
vascular walls, and this perivascular noradrenergic input, together with that of the cerebral
cortex, almost completely disappeared after DSP-4 administration. When analyzed at the
ultrastructural level in control rats, NA terminals in the neuropil had a mean surface area
of 0.53 0.03 m2 and were rarely junctional (synaptic incidence close to 7%). Perivascular
terminals (located within a 3-m perimeter from the vessel basal lamina) counted at the
electron microscopic level represented 8.8% of the total NA terminals in the cortical tissue.
They were smaller (0.29 0.01 m2, P < 0.05) than their neuronal counterparts and were
located, on average, 1.34 0.08 m away from intracortical blood vessels, which consisted
mostly of capillaries (65%). None of the perivascular NA terminals engaged in junctional
contacts with surrounding neuronal or vascular elements. The primary targets of both
neuronal and perivascular NA nerve terminals consisted of dendrites, nerve terminals,
astrocytes, and axons, whereas in the immediate vicinity (0.25 m or less) of the
microvessels, astrocytic processes represented the major target. The results of the current
study show that penetrating arteries and intracortical microvessels receive a central NA
input, albeit parasynaptic in its interaction, originating from the locus ceruleus.
Particularly, they point to frequent appositions between both neuronal and perivascular
NA terminals and astroglial cells and their processes. Such NA neuronal-glial and
neuronal-glial-vascular associations could be of significance in the regulation of local
metabolic and vascular functions under normal and pathologic situations.
