The Etiology of TOS is compression of the subclavian vein, artery, and/or nerves of the brachial between the color bone and the first rib.
Depending on which structure is compressed the patients can experience massive swellings of the arm due to clots in the veins. If the nerve is being compressed some patients can’t lift their hand above their head without experiencing pain.
This is common in younger and middle aged patients. When the arteries are compressed it can cause problems in the hand with lack of blood flow.
