If a patient with hand sweating has the above mentioned manifestations, active surgical treatment is recommended. The thoracoscopic sympathetic nerve truncation for hand sweating without sequelae The treatment of hand sweating includes medication, surgery, although medication can achieve the purpose of treatment, but the effective time is short, the recurrence rate is high, the current more ideal surgical procedure is thoracoscopic sympathetic nerve truncation. Thoracic sympathetic nerve trunk dissection for hand sweating only opens a small opening of 1 to 2 cm in the axilla of the patient’s chest wall, accurately and quickly blocking the patient’s thoracic sympathetic nerve. So far, thoracoscopic thoracic sympathetic nerve dissection has become the treatment of choice for hand sweating, and patients are discharged from the hospital to live a normal life with definite efficacy.
