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.

Parry-Romberg syndrome and sympathectomy--a coincidence?

Parry-Romberg syndrome is a clinical entity consisting of progressive hemifacial atrophy appearing at a young age. Animal studies indicate that sympathectomy can produce hemifacial atrophy. To our knowledge, this is the first report of a patient with a possible association between Parry-Romberg syndrome and thoracoscopic sympathectomy.

Overall, gustatory sweating occurred in 32% of patients

Gustatory sweating is a frequent side effect after thoracoscopic sympathectomy. This is the first study to report that its incidence is significantly related to the extent of sympathectomy or the location of primary hyperhidrosis. Although there is no pathophysiologic explanation of gustatory sweating, these findings should be considered before planning thoracoscopic sympathectomy and patients should be thoroughly informed.

Hyperhidrosis versus compensatory sweating: is it a treatment benefit or a risk of a new problem?

Side-effects of Sympathectomy treated with further surgical procedure and botox

Compensatory hyperhidrosis: a consequence of truncal sympathectomy treated by video assisted application of botulinum toxin and reoperation.
Surgical management of primary hyperhidrosis by upper dorsal sympathectomy is the treatment of choice for intractable hyperhidrosis, however, paradoxically it may be followed by troublesome compensatory hyperhidrosis in a significant number of patients. 
We report for the first time the successful treatment of a patient who developed compensatory hyperhidrosis following sympathectomy using video assisted extension of the sympathectomy by application of botulinum toxin (BTX-A).

Sympathicotomy affects cutaneous blood flow, temperature, and sympathicus-mediated reflexes

To study the sympathetically mediated effects of transthoracic endoscopic sympathicotomy (TES) in the treatment of severe primary palmar hyperhidrosis. MATERIALS AND METHODS: The effects of TES, on sympathetic ganglia at the thoracic level of 2-3, finger blood flow, temperature, and on heat and cold provocation were investigated. Middle cerebral artery (MCA) blood flow velocities were studied by transcranial Doppler. RESULTS: The finger blood flow increased by about 700% after TES and finger temperature by 7.0 +/- 0.5 degrees C. Several autonomic reflexes were dramatically affected. A finger pulp-shrinking test showed a major decrease after surgery. MCA mean blood flow velocities were not affected by TES. CONCLUSIONS: Besides the high success rate of good clinical effect of TES on palmar hyperhidrosis, major effects on local blood flow and temperature are elicited by TES. Complex autonomic reflexes are also affected. The patient should be completely informed before surgery of the side effects elicited by TES.
