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 can impair the autonomic nervous system’s increase of the heart rate in response to exercise


it has been shown that thoracic sympathectomy can impair the autonomic nervous system’s increase of the heart rate in response to exercise [6]. Although absolute tachycardia is not eliminated, given the endocrine and paracrine stimuli during exercise, the maximum heart rate reached during exercise has been shown to be significantly reduced after sympathectomy. Thus for a given workload during exercise, there will be a relative bradycardia. This may possibly affect the circulatory system’s ability to convey heat from the body core to the extremities for heat loss.
