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.

Sympathetic chain ganglia are responsible for delivering information to the rest of the body regarding stress situations and the fight or flight response

Sympathetic chain ganglia are responsible for delivering information to the rest of the body regarding stress situations and the fight or flight response. These sympathetic ganglia are the structures that are destroyed during a sympathectomy.

The so called 'compensatory sweating' is NOT compensatory:


"When patients with intense CH are analyzed, we observe that the amount of released sweat seems to be much greater than was that occurring at the primary hyperhidrosis location, not translating a simple compensation or sweating transference from one site to the other. Therefore, this hyperhidrosis seems to be reflex, mediated neurologically in the sweating regulatory center in the hypothalamus.

In order to avoid this neurologically mediated reflex, the sympathetic afferents to the hypothalamus should be restored, allowing negative feedback to block the efferent projection of the sweating regulatory center on the periphery.(14) Therefore, only the reinnervation of the sectioned sympathetic chain could recover this reflex."
