Idiopathic proximal ulnar artery aneurysm

Abstract

Ulnar artery aneurysms are very rare, usually caused by repetitive blunt trauma to the ulnar artery, leading to the formation of an aneurysm. Other etiologies reported in the literature were vasculitis, anatomic abnormalities, or infections. This case report is regarding a 29-year-old male who presented with proximal ulnar artery aneurysm with distal embolization. He underwent aneurysm resection with ligation of the ulnar artery. Histopathology of the aneurysmal wall showed true aneurysm of the ulnar artery.
