A case of true brachial artery aneurysm in an elderly male.

Brachial artery aneurysms are relatively rare and are mostly pseudoaneurysms rather than true aneurysms, as true aneurysms are even rarer entities. Patients can be asymptomatic, or present with pulsatile masses, or ischemia due to associated thromboembolic complications. Distal embolism can occur with transient or minimal ischemic symptoms; however, aneurysm itself can thrombose entirely. The authors report a case of upper limb acute ischemia caused by true brachial artery aneurysm thrombosis in an elderly man, managed by reconstructive vascular surgery.
