Tortuous axillary artery aneurysm causing median nerve compression.

Axillary artery aneurysms are rare entities that warrant surgical intervention. Reported complications include thrombosis, distal embolization, and debilitating neurologic symptoms caused by median nerve compression. Common etiologies include trauma or repetition injuries. Less recognized associations include atherosclerotic, connective tissue, or mycotic processes. We report a case of a rare tortuous axillary artery aneurysm causing neurologic symptoms in a woman with an unused arteriovenous fistula. Published by Elsevier Inc.
