What is Thoracic Outlet Syndrome?
Sometimes referred to as “TOS”, thoracic outlet syndrome is an umbrella term that is used to describe a group of disorders that come from compression or irritation of the nerves and/or blood vessels in the lower neck and upper chest area. This compression causes pain in the arm, shoulder, and neck. Thus, decompression surgery is required.
There are 3 classifications of thoracic outlet syndrome:
- Neurogenic thoracic outlet syndrome (most common)
- Venous thoracic outlet syndrome
- Arterial thoracic outlet syndrome

What are the symptoms of Thoracic Outlet Syndrome?
Symptoms of thoracic outlet syndrome depend on the type of TOS syndrome you have. It is possible to have a combination of the different types of thoracic outlet syndrome, so proper diagnosis is important.
The following are the most common symptoms of all 3 types of thoracic outlet syndrome:
- Numbness or tingling in arm or fingers
- Arm pain and swelling
- Discoloration of the hand (blue color)
- Weak grip
- Arm fatigue
- Arm pain, neck pain, or shoulder needing pain management
- Cold fingers, hands, or arms from poor circulation
Treatment Options for Thoracic Outlet Syndrome
If thoracic outlet syndrome is left untreated you could be at risk for permanent arm pain and/or swelling, gangrene, pulmonary embolism, or permanent nerve damage. The goal of treatment for thoracic outlet syndrome is to manage pain through decompression surgery.
Early diagnosis can help improve treatment outcomes. Most patients with thoracic outlet syndrome are treated with physical therapy or medical management with pain medications, thrombolytics, or anticoagulants. About 10-20% of patients with thoracic outlet syndrome will need surgical intervention.

It's important to remember not all physicians are trained in advanced vascular and endovascular surgery. It’s a good practice to get multiple opinions and do research on the surgery and the physician.
