Currently, most clinical hand sweats are primary. Studies have shown that hand sweating is mainly due to sweat gland secretion, which in turn is controlled by sympathetic nerves in the thoracic cavity; when the sympathetic nerve tissue, for unknown reasons, has an increased number of myelinated nerve fibers, hyperactive nerve conduction occurs (i.e., increased sympathetic activity); thus controlling the sweat glands to accelerate the secretion of hand sweat per unit of time, resulting in hand sweating disorder. The general treatment of hand sweating is mainly through the atrophy/destruction of sweat glands and the inhibition of their secretion in order to achieve temporary relief of excessive hand sweating. Obviously, these methods do not address the root cause of the problem, and not only do they fail to achieve the desired effect, but they also delay treatment and consume a lot of time and energy. Compared to traditional drug treatment, the fluorescent ETS minimally invasive technique for hand sweating is more accurate and long lasting, and basically does not affect the original health of the body. This technique is fluorescence staining by non-radioactive, non-toxic fluorescent contrast agent, which can quickly, accurately and clearly observe the direction and distribution of the thoracic sympathetic ganglion and its variant nerves within the wall pleura and connective tissue, facilitating the differentiation of other normal tissue structures around it, avoiding the existence of omissions in the treatment, thus achieving safer, finer and more complete regulation of the treatment, avoiding This allows for a safer, more delicate and more complete treatment, avoiding damage to other nerves and normal tissues, providing more accurate treatment results and greatly reducing postoperative complications of hand sweating, thus benefiting more patients with hand sweating.
