Aneurysms of the upper extremity mostly originate from trauma, mycotic lesions, thoracic outlet syndrome, previous arteriovenous fistulae, and atherosclerosis. True aneurysms of the brachial and axillary artery are encountered rarely. They can be diagnosed by simple physical examination as a pulsatile mass. However, most of these aneurysms remain asymptomatic until a complication occurs. The primary complication seen with the axillary or brachial artery is embolization. We report 3 large-diameter true brachial artery aneurysms extending to the axillary zone. One of the patients had distal digital emboli causing gangrenous lesions at the finger tips and the other 2 patients had pain and ischemic symptoms in the forearm. All underwent surgical repair. After excision of the aneurysmal segment, arterial continuity was ensured by interposition of a reversed saphenous vein in 2 patients and with a biological vascular graft in 1 patient. Although endovascular techniques are improving, most true brachial artery aneurysms are not anatomically suitable for interventional procedures. Open surgery still preserves its value.
