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.

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.

the Kuntz nerve played no part in the success or failure of ETS surgery

If you research the topic of ETS, you will come across various claims and counter-claims
about the importance or otherwise of the Kuntz nerve. The Kuntz nerve is a small nerve
fibre sometimes seen on the second rib not far from the main sympathetic chain. Its
function is not known in humans. Some web-sites on ETS claim success rates of up to
100% for facial blushing because they search for and destroy the Kuntz nerve(s). These
same people also claim to be able to correct failed ETS operations by reoperating and
destroying the Kuntz nerve.
At the meeting of the International Society for Sympathetic Surgery in Germany, May
2003, attended by a majority of the world’s experts in ETS surgery (including us), all but
one of the surgeons present were of the opinion that the Kuntz nerve played no part in the
success or failure of ETS surgery for facial blushing. We share this majority opinion.

Sympathectomy is a technique about which we have limited knowledge, applied to disorders about which we have little understanding."

Following sympathectomy the basal t-PA activity in plasma was 70% less than controls

Following sympathectomy: (i) the basal t-PA activity in plasma was 70% less than controls (2.92 ± 1.96 versus 9.33 ± 1.72 IU/ml;P ≤ 0.001); (ii) the acute release from isolated vessels induced by bradykinin or phenylephrine was comparably reduced; and (iii) the greatest reductions occurred in densely innervated small vessel explants. The results provide new support for an autonomic regulation of neural t-PA release into the vessel wall matrix and blood of densely innervated thin-walled microvessels.

POSTSYMPATHECTOMY PAIN AND CHANGES IN SENSORY NEUROPEPTIDES

Postsympathectomy limb pain, postsympathectomy parotid pain, and Raeder's paratrigeminal syndrome are pain states associated with the loss of sympathetic fibres and in particular with postganglionic sympathetic lesions. There is a characteristic interval of about 10 days between surgical sympathectomy and onset of pain. It is proposed that this pain in man is correlated with the delayed rise in sensory neuropeptides seen in rodents after sympathectomy. These chemical changes probably reflect the sprouting of sensory fibres and may result from the greater availability of nerve growth factor after sympathectomy. The balance between the sensory and sympathetic innervations of a peripheral organ may be determined by competition for a limited supply of nerve growth factor.

link between sympathectomy and osteoclast-mediated bone resorption

Recent investigations have demonstrated a link between sympathectomy and osteoclast-mediated bone resorption. The exact nature of this link, however, is unknown, We hypothesize that substance P, a potent vasoconstrictive neuropeptide found in peripheral sensory fibers, including those innervating bone, is the mediator of this phenomenon. To test this theory, the effects of substance P on in vitro calcium release from cultured neonatal mouse calvaria were assessed. In addition, an in vivo study was conducted whereby gerbils were injected with capsaicin to eliminate substance P-containing fibers before sympathectomy with 6-hydroxydopamine. If the effects of 6-hydroxydopamine were eliminated by prior administration of capsaicin, the role of sensory nerves in sympathectomy-induced resorption would be strongly implicated.


The results indicate that substance P is capable of inducing resorption and that substance P-containing sensory nerves are required for the induction of resorption after sympathectomy in the gerbil.
