Surgical interventions sympathectomy

Sympathectomy is the dissection or coagulation of sympathetic nerve nodes and may be done to reduce excessive sweating of the axillae. This procedure is now done by endoscopy (introducing instruments through the skin via a narrow tube) rather than by opening the chest surgically, but a general anaesthetic is still required. The lungs are collapsed by pumping in carbon dioxide, and the sympathetic nerve nodes that transmit the nervous signals to the sweat glands in the upper limb and the face (T1-T4) are destroyed.
