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.

Morphofunctional changes in the myocardium following sympathectomy and their role in the development of sudden death

A comprehensive study revealed 2 main stages in the sympahtectomy caused by reserpine. In the early stages, the functional and metabolic changes in the heart muscle are caused by a dramatic reduction in the activity of the sympathoadrenal system with a relatively preserved structure of the myocardium. The second stage of the sympathectomy is marked by demonstrable morphological and metabolic abnormalities in the myocardium, thereby leading to the occurrence of irreversible fibrillation or hte heart ventricles.
