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.

reductions in heart rate variability are a predictor of sudden cardiac death, even in individuals without a prior history of cardiovascular disease

Research indicates that a highly variable heart rate increases your capacity to respond and adapt to life’s challenges.
In a sense, it makes your cardiovascular system more flexible. If you’re less able to switch to the rest system, you’re more likely to feel stressed because your body is indicating that there’s danger in the environment – even if there isn’t.
Research has shown that reductions in heart rate variability are a predictor of sudden cardiac death, even in individuals without a prior history of cardiovascular disease.
