Thoracic Outlet Syndrome
may be the result of an anomalous cervical rib
that compresses the lower trunk of the brachial plexus, subclavian artery, or both.
Clinical findings include
atrophy of thenar and hypothenar eminences, atrophy of interosseous muscles, sensory deficits on the medial side of forearm and hand, diminished radial artery pulse upon moving the head to the opposite side, and a bruit over the subclavian artery. The angiogram, taken with abduction of both arms, shows that blood flow is partially occluded in the subclavian arteries (arrows).
