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.

In all cases wrinkling was abolished after interruption of the hand sympathetic innervation

In the study, the effect ofcervical sympathectomy on water immersion wrinkling was examined in 12 patients treated for palmar hyperhidrosis.

In all cases wrinkling was abolished after interruption of the hand sympathetic innervation. A separate study in patients with diabetic neuropathy noted that reduced or absent water immersion wrinkling was linked to autonomic dysfunction as indicated by diarrhea and orthostatic hypotension [3]. Two clinical studies on patients with leprosy further strengthened deficient water immersion wrinkling as an indicator ofperipheral sympathetic nerve damage [14,18]. Interestingly, central nervous system sympathetic dysfunction has also been shown to affect finger wrinkling.In a study of patients with unilateral Parkinsonism, wrinkling was significantly reduced on the side not affected by motor signs.
