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.

sympathectomy per se may sensitize peripheral nociceptors and lead to neuralgia

Interestingly, while is used for the treatment of some chronic pain conditions, sympathectomy per se may sensitize peripheral nociceptors to circulating norephinephrine, and this sensitization may lead to post-sympathectomy neuralgia. (p.287)

Compensatory hyperhidrosis reported in 0% to 74.5% of cases

Compensatory hyperhidrosis is the most common and unpredictable side effect of thoracoscopic sympathectomy and is reported to occur in 0% to 74.5% of cases. (p.555)

cerebral edema following CO2 insufflation

Death after thoracoscopic sympathectomy has been reported, secondary to cerebral edema, when CO2 insufflation has been employed. Another patient in this series sustained severe neurological dysfunction, secondary to cerebral edema. The development of cerebral edema after thoracoscopic sympathectomy is attributable to gas insufflation, which is not required and should be avoided. Major vascular injury during thoracoscopic sympathectomy has also been reported, and this complication should be completely avoidable. Chylothorax after sympathectomy has also been described and is related to division of accessory ducts rather than injury to the thoracic duct.
The most common complications of sympathectomy are related to manipulation of the autonomic nervous system.

Injury to the stellate ganglion is caused by mechanical or thermal damage to T1 during dissection. In order to prevent this injury, precise identification of ribs 1-4 is required prior to dissection of the sympathetic ganglion at T2; no dissection is performed above this level. Furthermore, excessive nerve traction is avoided during dissection. Finally, the use of bipolar cautery or ultrasonic dissection will prevent current diffusion to the stellate ganglion.
Neuralgia along the ulnar aspect of the upper limb may occur after sympathectomy, which usually resolves within 6 weeks. (p.250)

Complications in cardiothoracic surgery: avoidance and treatment

"Sympathectomy is another animal."

Sympathectomy. This is a radical, now-controversial approach to blocking pain, and it includes extremely high risks for additional tissue damage and spread of RSD. (p.40)

Sympathectomy also potentially precludes future new treatments from working. (p.41)

A recent review article by (Johns Hopkins Hospital anesthesiologist and medical school professor) Srinivasa Raja covering all previous articles on sympathectomy showed that 10 percent of sympathectomies done for various reasons have complications. The complication rate for sympathectomy done to treat neuropathic (i.e., RSD) pain is 30 percent. A lot of these people can have a return of pain, and if they do, you can no longer do a sympathetic block to get rid of it. Then you have got these people in terrible pain that you cannot treat. And so, in my book, surgical sympathectomy is out. (p.81)

Post-Sympathectomy pain (neuralgia)

Post-Sympathectomy pain (neuralgia) is a potential complication of all types of sympathectomy. Post-Sympathectomy pain is typically proximal to the original pain (e.g. proximal means that the pain may appear for the first time in the groin or buttock region for sympathectomy of the lower extremity and pain in the chest wall region for sympathectomy of the upper extremity).

Sympathectomy considered a last resort or end-of-the-road treatment

Surgical sympathectomy has been advocated for patients who do not get permanent pain relief from blocks and is somewhat of a last resort or end-of-the-road treatment. (p.469)

lung and nerve problems

Even with newer endoscopic techniques, the complications can include excessive sweating in other parts of the body and lung and nerve problems. As many of these complications are serious and not reversible, this option is rarely used, and then only as a last resort.
