Ischemia of the Thumb: A Rare Case of Emboli to the Princeps Pollicis Artery

Abstract

Acute digital ischemia is relatively rare due to collateral blood supply to the hand from ulnar and radial arteries. We present a case of thumb ischemia secondary to embolic occlusion of the princeps pollicis artery, a branch of the radial artery, with concomitant atherosclerotic occlusion of the ipsilateral subclavian artery. This case highlights the importance of thorough investigation for systemic causes of distal upper extremity ischemia.
