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.

a reduction of the muscular tone and to a secondary neurovascular disorder at the edge of the sympathetic denervation zone

Surgical sympathectomies and chemical sympatholyses bring about a true sympathetic deafferentation. This leads to central retrograde degenerescence reactions of the pre-ganglionic neurons, to a reduction of the muscular tone and to a secondary neurovascular disorder at the edge of the sympathetic denervation zone.
