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.

Cold Hypersensitivity after Sympathectomy for Raynaud's Disease

Two patients with socially handicapping Raynaud's disease underwent bilateral upper thoracic sympathectomy. One to two days after the operation, both developed local hypersensitivity to cold in the form of a rebound. The cold hypersensitivity persisted in one of the patients, although complete degeneration of vasoconstrictor fibres was proven by absence of the sympathetic veno-arteriolar reflex after sympathectomy. Pre-operative sympathetic blockade could not predict the outcome of sympathectomy.
