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.

Sympathectomy on Neuropeptide Y

Neuropeptide Y (NPY)-immunoreactive nerve fibers were numerous around arteries and few around veins. NPY probably co-exists with noradrenaline in such fibers since chemical or surgical sympathectomy eliminated both NPY and noradrenaline from perivascular nerve fibers and since double staining demonstrated dopamine-β-hydroxylase, the enzyme that catalyzes the conversion of dopamine to noradrenaline, and NPY in the same perivascular nerve fibers.

Neuropeptide Y co-exists and co-operates with noradrenaline in perivascular nerve fibers
