What Is Thoracic Outlet Syndrome?
Thoracic outlet syndrome occurs when blood vessels or nerves become pinched or compressed between the clavicle (collarbone) and the first rib, leading to pain in the shoulders and neck or numbness in the fingers.
Learn more about the signs and symptoms of thoracic outlet syndrome, along with preventative steps, and the treatments we offer to help get you back to normal life.
Causes Of Thoracic Outlet Syndrome
Thoracic outlet syndrome is often caused by injury, such as a car accident or job- or sports-related activities. Physical therapy and surgery may be used to relieve symptoms caused by thoracic outlet syndrome.
Signs & Symptoms Of Thoracic Outlet Syndrome
Since there are both blood vessels and nerves that pass through the narrow space between the clavicle and first rib, thoracic outlet syndrome may be vascular, neurological, or both.
When nerves are compressed, symptoms may include:
- Numbness or tingling in the arm or fingers
- Pain or achiness in the neck, shoulder, or hand
- Weakened grip
- Muscle atrophy in the base of the thumb
When blood vessels are compressed, symptoms may include:
- Bluish discoloration or paleness in the hand or fingers
- Arm pain and swelling
- Blood clots in the upper body
- Weak or no pulse in the affected arm
- Arm fatigue, especially with exertion
- Coldness, numbness, or tingling in the arms, hands, or fingers
Risk Factors
Several risk factors can increase the chances of developing thoracic outlet syndrome:
- Age (most common in adults aged 20–40)
- Sex (more common in females)
- Pregnancy
- Anatomical defects (such as an extra rib or unusually tight fibrous band)
Prevention Of Thoracic Outlet Syndrome
While thoracic outlet syndrome cannot always be prevented, the following steps can help reduce your risk:
- Avoid repetitive movements that put strain on the shoulder and neck
- Maintain a healthy weight
- Avoid carrying heavy bags on your shoulders
- Stretch daily, especially if you perform repetitive tasks
- Exercise and strengthen the muscles around the shoulder and thoracic outlet
Treatment Of Thoracic Outlet Syndrome
Vascular & Interventional Specialists offers treatment options for thoracic outlet syndrome, including:
- Rib resection — Surgical removal of an extra rib or portion of the first rib to give the thoracic outlet additional room
- Sympathectomy — The surgeon clamps the sympathetic nerve, preventing pain signals from reaching the brain
- Physical therapy — Targeted exercises to strengthen and stretch the muscles around the thoracic outlet
Complications Of Thoracic Outlet Syndrome
If left untreated, thoracic outlet syndrome can lead to permanent neurological damage. Early diagnosis and treatment are essential to prevent long-term complications.
