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.

Peripheral SNS and Cerebral Blood Flow

Immediately following experimentation the cerebral vessels were examined
for the presence of noradrenergic fibers. The results of the study demonstrate that: (1) superior
cervical ganglionectomy produces a significant reduction in the noradrenergic innervation of ip-
silateral extraparenchymal arteries; (2) the peripheral sympathetic nervous system contributes
to overall cerebral vascular resistance primarily by affecting resistance in extraparenchymal
arteries; and (3) as a result, it determines the contribution of the extraparenchymal arteries tooverall cerebral blood flow autoregulation.
