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.

Relationship of cerebral bloodflow and metabolism to neurological symptoms

Reduced cerebral vascular tone

This is manifested by the following rheoencephalographic findings: steep rise of the anacrotic section of the curve, high amplitude, sharp peak, overt incisure with low localization (in the lower third of the curve or very close to the baseline), prominent post-incisure wave. These rheoencephalographic changes may be observed after inhalation of 5 to 7% CO2 or cervical sympathectomy (Jenkner, 1962), resulting in dilation of the cerebral vessels. Analogous deviations may be induced by vasodilative drugs.
UnderThese signs of reduced cerebral vascular tone may be observed alsi in a variety of pathologic conditions associated with cerebral hyperemia, such as contusion of the brain (Jenkner, 1962), following electroshock (Lifshitz. 1963) and others.
