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.

Long QT syndrome is a genetic abnormality that can lead to VT and cardiac arrest. The diagnosis is usually made by a 12 lead ECG, but an exercise test may be required to identify those with latent long QT syndrome manifest as a lack of QT shortening during exercise. Beta-blockade remains the mainstay of treatment, especially in the type l and ll subtypes, but symptomatic patients despite beta-blockade may require defibrillator implantation or sympathectomy. Long QT type 3 patients are at particular risk as their first presentation may be sudden cardiac death, and prophylactic implantation of an ICD is recommended.
