Thoracic Outlet Syndrome
Thoracic outlet syndrome (TOS) is a constellation of upper extremity symptoms resulting from compression of the brachial plexus, subclavian artery, and subclavian vein as they pass between the clavicle and the first rib. The majority of patients are between 20 and 50 years of age and about 70% are females. There are three types of TOS: neurogenic, arterial, and venous. Despite the variability in presenting symptoms, the therapy is often decompression of the thoracic outlet. This is achieved with a first rib resection which can be performed through a supraclavicular, infraclavicular, or trans-axillary approach. A vascular intervention may also be required to treat symptomatology from chronic compression.
