Thoracic Outlet Syndrome (TOS)

Compressed blood vessels and nerves

Thoracic outlet syndrome involves pinching and compression of the nerves and blood vessels in the space between the collarbone and the first rib. The doctors in our Vascular and Endovascular Program are recognized leaders in treating patients with disorders such as this, and we’re on the forefront of the most advanced treatment techniques available.

Thoracic outlet syndrome can cause swelling, discoloration, weakness, numbness or pain in the shoulder, arm and fingers. Sports that involve repeated shoulder movement, such as baseball or swimming, may increase your risk, as can injuries to the back or neck, poor posture or defects defects present from birth.

There are a number of types of thoracic outlet syndrome, including axillo-subclavian vein thrombosis. Without proper treatment, the condition can lead to serious problems, including death of tissue (gangrene), blood clots or a pulmonary embolism.

Tests

Your doctor will try to reproduce your symptoms by having you move your arms, neck and shoulders in various positions. You also may need one or more tests to confirm a diagnosis of thoracic outlet syndrome.

Treatments

Physical therapy and medications may help relieve your symptoms and reduce your risk of a dangerous blood clot. If these approaches aren’t enough, you may need a surgical procedure called thoracic outlet decompression.
