Sympathectomy for hyperhidrosis is accomplished by making a small incision under the armpit and introducing air into the chest cavity. The surgeon inserts a fiberoptic tube (endoscope) that projects an image of the operation on a video screen. The...
ganglia are cut with fine scissors attached to the endoscope. Laser beams may also be used to destroy the ganglia.
If only one arm or leg is affected, it may be treated with a percutaneous radiofrequency technique. In this technique, the surgeon locates the ganglia by a combination of x ray and electrical stimulation. The ganglia are destroyed by applying radio waves through electrodes on the skin.
In this video, the basic building block of the nervous system, the neuron, is described. Countless neurons are joined and organized to form the nervous system, also described in this animation.
Sympathectomy is a surgical procedure that destroys nerves in the sympathetic nervous system. The procedure is done to increase blood flow and decrease long-term pain in certain diseases that cause narrowed blood vessels. It can also be used to decrease excessive sweating. This surgical procedure cuts or destroys the sympathetic ganglia, collections of nerve cell bodies in clusters along the thoracic or lumbar spinal cord.
Surgery for removal is generally advised for patients with limited cancer elsewhere in the body and a single brain metastasis.
