Reports bilateral brachial artery aneurysms and acute forearm ischemia in a chronic axillary crutch user, highlighting upper-extremity vascular risks of repetitive crutch trauma.
A 57-year-old man, who was a chronic axillary crutch user as a result of childhood poliomyelitis, was referred to our hospital because of a sudden onset of right forearm ischemia. The right forearm had no pulse, and three-dimensional computed tomography (3DCT) showed an aneurysm of the right brachial artery associated with arterial occlusion. The thrombosed aneurysm of the brachial artery was resected and the brachial artery was successfully revascularized by interposing a saphenous vein graft. Postoperative 3DCT revealed an asymptomatic left brachial artery aneurysm. His postoperative course was uneventful under warfarin anticoagulation therapy.
