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.

Satisfaction rates of patients following sympathectomy significantly decreased in the long term

Studies by ETS surgeons have claimed an initial satisfaction rate around 85-95% with at least 2%-19% regretting the surgery and up to 51% of the patients complaining about decreased quality of life.192021One study shows a satisfaction rate as low as 28.6. Most patients report various adverse reactions as a result of the surgery. However, ETS surgeon Samuel S. Ahn of UCLA claims "100% success with no negative side effects".22
A large study of psychiatric patients treated with this surgery showed significant reductions in fear, alertness and arousal. (Teleranta, Pohjavaara, et al. 2003, 2004). Arousal is essential to consciousness, in regulating attention and information processing, memory and emotion.23 This study also proves what many patients have claimed, that the surgery caused psychological changes.
