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 will block the chronotropic response

Around 50% of patients have bradycardia in the following minutes of a bilateral surgery with mean and diastolic blood pressure significant reduction. Since the sympathectomy will block the chronotropic response, a significant increase of the ejection volume is observed when the patient moves in the erect position from dorsal decubitus [6]. Two cardiovascular complications were reported in the literature. First, an asystolic cardiac arrest in an 18-year-old woman during the second side (left) of bilateral sympathectomy for severe hyperhidrosis, requiring resuscitation maneuvers, with no chronic sequelae [7]. The second case was reported in a 23-year-old woman in whom a bilateral T2 sympathectomy was performed for facial hyperhidrosis. Two years later, following electrophysiologic studies confirming unopposed vagotonic stimulation, she underwent permanent pacemaker insertion for symptomatic bradycardia [8].
