Primary brachial artery aneurysm with associated basilic vein aneurysm

Abstract

ABSTRACT There are but a handful of reported brachial artery aneurysms, the majority of which are pseudoaneurysms or false aneurysms caused by trauma or fistula creation. True or primary brachial artery aneurysms are even more rare, and if they occur, they often do so in isolation. In this case report, we discuss the interesting finding of a large primary brachial aneurysm together with an adjacent aneurysmal basilic vein identified intra-operatively. This presentation was 21 years after the renal transplant and ligation of an arteriovenous fistula in that same arm. It is noteworthy that the fistula was in the forearm and far away from the site of the untouched brachial area.
