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.

hypoxaemia, a potentially serious complication of Sympathectomy

Consecutive series of patients (n = 210), suffering from upper limb hyperhidrosis, anaesthetised for TES.

SpO2 decreased below 98% in 58 patients. Sudden hypotension and bradycardia in two patients.
The mean PaO2 was significantly (p = 0.03) decreased during two-lung ventilation (TLV), after reinflation of the right lung, compared with TLV after endobronchial intubation. There was no significant difference in mean PaO2 during one-lung ventilation of both lungs. Lowest PaO2 observed during one-lung ventilation was less than 13.3 kPa in three sympathectomies. Postoperative pain, severe on awakening and mainly retrosternal, was relieved with i.v. opiates. CONCLUSION: Controlled ventilation with 100% inspired O2, SpO2 monitoring and one to two gentle manual ventilations when it decreases is the cornerstone of the management of hypoxaemia, a potentially serious complication of TES.
