For minimally invasive thoracoscopic surgery in patients with hand sweating, the patient requires general anesthesia; after the anesthesia takes effect, two tiny 0.5 cm incisions are made under the axillae bilaterally; the sympathetic nerve chain is found next to the spine under the lumpectomy and is cut. The operation takes about 10 minutes on one side, which is a very short procedure with very definite results. This procedure is minimally invasive, has hidden incisions, is cosmetic, is less painful, has a relatively quick post-operative recovery, and the patient can be discharged the next day. The only effective treatment for hand sweating at present is bilateral sympathetic nerve chain severance. Previously, the traditional open-heart surgery treatment was so surgically invasive that it discouraged patients. With the development of medical devices and the advancement of medical technology, minimally invasive thoracoscopic surgical treatment has led to satisfactory treatment results for patients with hand sweating. In addition, patients can be treated surgically after being hospitalized to improve basic examinations such as electrocardiogram, chest X-ray and blood test, and there are no clear contraindications to surgery.
