3 Things You Need To Know About Thoracic Outlet Syndrome

Thoracic outlet syndrome occurs when the nerves or blood vessels that pass through your thoracic inlet become compressed. Your thoracic inlet is the opening at the top of your chest cavity, in between your collarbone and your first pair of ribs. Here are three things you need to know about thoracic outlet syndrome.

What are the signs of thoracic outlet syndrome?

The signs of thoracic outlet syndrome vary based on whether it's your nerves, blood vessels, or both that are being compressed. If only your nerves are being compressed, you'll experience weakness, loss of sensation, or paresthesia (tingling sensation) in your hands. Pain in your forearms and hands can also occur.

If only your blood vessels are being compressed, you'll notice that your arms and hands are changing color, becoming cramped, or becoming sore. Eventually, the lack of blood flow can lead to problems like ulceration or gangrene in your upper limbs. Pain can also occur with this type of compression.

If both your nerves and blood vessels are affected, you'll experience all of the above symptoms.

What causes thoracic outlet syndrome?

Compression of the nerves and vessels that pass through your thoracic inlet can happen for many reasons. In some cases, it can be the result of unique anatomical features. For example, if you were born with an extra rib above your first rib, that could cause compression.

Trauma may also lead to this condition. For example, if you get into a car accident or have a bad fall, the resulting swelling can compress your nerves or blood vessels.

Repetitive movements may also cause this condition. These repetitive movements can be job-related, like spending all day stocking shelves or typing on your computer, or sports-related, like spending hours perfecting your butterfly stroke.

Your doctor will be able to determine the cause of your thoracic outlet syndrome after examining you.

Can it be treated?

If your blood vessels are being compressed, you'll need to have surgery, specifically first rib resection. During this procedure, part of your first rib will be removed. Removing this tissue makes your thoracic inlet larger and takes the pressure off of your blood vessels.

If only your nerves are being compressed, non-surgical methods are the first line of treatment. This includes avoiding activities that make your symptoms worse, like making repetitive movements with your arms. Anti-inflammatory medications, muscle relaxants, and physiotherapy are also used. If you're not feeling better within eight to 12 weeks, you'll need to undergo first rib resection.
