Which condition is characterized by compression of the subclavian artery and brachial plexus?

The condition characterized by the compression of the subclavian artery and the brachial plexus is thoracic outlet syndrome. This syndrome occurs when the blood vessels and nerves are compressed as they pass through the thoracic outlet, which is the space between the collarbone and the first rib. The compression can lead to a variety of symptoms, including pain, numbness, and weakness in the arm and hand, as well as circulation issues.

In contrast, Raynaud's phenomenon primarily involves blood flow issues to the fingers and toes due to spasms in the small arteries, usually triggered by cold or stress, rather than a structural compression. Carpal tunnel syndrome is related to compression of the median nerve at the wrist, which does not involve the subclavian artery or brachial plexus. Peripheral artery disease refers to the narrowing of peripheral arteries, typically in the legs, due to plaque buildup, and does not specifically involve the thoracic outlet area or neural structures. Thus, thoracic outlet syndrome is the correct association with the compression of both the subclavian artery and the brachial plexus.
