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.

Thoracoscopic sympathectomy for palmar hyperhidrosis: effects on pulmonary function.

Palmar hyperhidrosis, probably caused by an over-reactivity of sympathetic nerves passing through the second and the third thoracic sympathetic ganglia (T2 & T3 ganglia), can only be cured by sympathectomy. Such sympathetic denervation may also alter pulmonary function. In order to investigate the effect of sympathectomy, pulmonary function was compared before and four weeks after operation in 20 patients. Forced vital capacity (FVC) (-2.3%), forced expiratory volume in one second (FEV1) (-6.1%), and FEV1/FVC (-4.6%) were all slightly but significantly decreased four weeks after thoracoscopic sympathectomy. Also the instantaneous forced expiratory flow at 75%, 50% and 25% of the FVC (Vmax25, Vmax50, Vmax75) in flow-volume curves were decreased (-1.6%, -8.4%, and -20% respectively).
