What are the types of thoracic outlet syndrome?
- Neurogenic TOS occurs when the nerves leading from the neck to the arm (the brachial plexus) is compressed.
- Venous TOS occurs when a vein is compressed, leading to upper body thrombosis.
- Arterial TOS occurs when an artery is compressed.
Can thoracic outlet syndrome affect legs?
Symptoms of Venous Thoracic Outlet Syndrome In this case, the clots are formed as the result of overhead motions (efforts) that compress the vein. Deep vein thrombosis is more common in the legs.
What muscles cause thoracic outlet syndrome?
Specifically, the sternocleidomastoid and scalenes shorten, which can alter the function of these muscles [22]. This can lead to an entrapment of the brachial plexus, subclavian artery, subclavian vein, or a combination of these vessels and tissues [2,19].
Is TOS an emergency?
Often this is temporary, happening only when your arm is raised. However, severe or long-term arterial TOS can damage the artery, cause clotting and require emergency medical attention. The most rare form, arterial TOS, requires surgery to decompress the thoracic outlet.
