Thoracic Outlet Syndrome
Thoracic outlet syndrome occurs when the blood vessels and nerves under the collarbone that travel to the arm are compressed between the collarbone and the first rib.
- Trauma to the shoulder or collarbone area
- An extra rib above the first rib
- Abnormally tight fibrous band (ligament) that connects the spinal vertebra to the ribs
- A long, muscular neck
- Droopy shoulders
- Poor posture
You may have thoracic outlet syndrome if you experience these symptoms:
- Pain, numbness and tingling in the last three fingers and inner forearm
- You repetitively extend your arms over your head or your arm turns pale when lifted.
- Weakness and fatigue in the forearm and hand muscles, particularly when doing something with your arms over the head like washing your hair
- Pain and tingling in the neck and shoulders, which may worsen if you carry something heavy
Treatment at UVA
Our specialists can diagnose you tests including:
- Upper extremity blood pressure evaluation
- Magnetic resonance imaging (MRI)
Your doctor may suggest physical therapy or surgery to alleviate the pressure and compression of the artery or nerves. Surgery may require removal of the first rib and the constricting bands and muscles.
If your problem is a result of a previous collarbone fracture, your doctor may remove your collarbone. A bypass may be required to reconstruct the artery if it's been compressed for a long time or is permanently injured.
