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.

SUPERSENSITIVITY TO NE AFTER ADRENERGIC DENERVATION

H-NOREPINEPHRINE UPTAKE
Portal veins were incubated for 1 hour with 3H-NE 1,3, and 5 days after chemical sympathectomy with 6-OHDA (Fig. 3). Preparations treated with cocaine (10~5 M) were exposed to this drug 15 minutes before 3H-NE incubation and maintained in a cocaine-containing solution throughout the entire incubation period. One day after 6-OHDA treatment, NE uptake was reduced to approximately 21 %
of control; at 3 days it was 33% of controls and 5 days after 6-OHDA it was approximately 39% of controls. The decrease in NE uptake caused by 6-OHDA treatment was comparable to that caused by cocaine.
