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.

Horner syndrome, pneumothorax, hemothorax, asymmetry of results, intercostal neuralgia, causalgia, hypoesthesia, incomplete results, paresthesia in the anterolateral abdominal wall, dyspareunia

The complications and side effects are very significant, such as irreversible compensatory sweating (20% to 50%), low satisfaction with results, Claude-Bernard-Horner syndrome, pneumothorax, hemothorax, asymmetry of results, intercostal neuralgia, causalgia, incomplete results, and anesthetic complications11-13.

Retroperitoneoscopic lumbar sympathectomy (video-assisted): this technique is effective in the treatment of isolated or persistent plantar hyperhidrosis (compensatory after thoracic sympathectomy). The treatment consists of removing the nerves of the sympathetic chain located in the abdomen, in the anterolateral portion of the lumbar vertebrae. It requires hospitalization and is carried out under general anesthesia. It may lead to complications such as lesions of structures adjacent to the sympathetic chain, light abdominal distension, neuralgia, and causalgia as well as hypoesthesia in the thighs and groin, limitation of leg movement,
paresthesia in the anterolateral abdominal wall, change in libido, dyspareunia, pulmonary thromboembolism, hemorrhages, arrhythmias, and cardiac decompensation, amongst others. It definitively eliminates plantar hyperhidrosis14,15.
