True Idiopathic Brachial Artery Aneurysm: A Rare Case of Surgical Emergency

We report a case of true brachial artery aneurysm of idiopathic origin in a 53-year-old man complicated by distal thromboembolism resulting in acute critical upper limb ischemia. True aneurysm of the brachial artery is a very rare condition which may be asymptomatic or rarely present with acute thromboembolic episode. Surgical repair is the mainstay of treatment in these cases.
