Multiple arterial aneurysms in association with aberrant brachial arterial anatomy and hemodialysis fistulas

Abstract This work describes two cases of multiple aneurysms of aberrant brachial arterial supply in association with ipsilateral hemodialysis fistulas. In the first case, a 38-year-old man presented with acute thrombosis of an aneurysmal left brachioradial artery. In the second case, a 34-year-old man was referred with the diagnosis of aneurysmal left brachiocephalic fistula. This turned out to be an aneurysmal brachioradial artery. In both patients, multiple true aneurysms of aberrant brachial arterial supply were observed. By nature, the brachioradial variation lies superficially in the arm. We discuss the pitfalls of such an anomaly in planning an ipsilateral arteriovenous fistula.
