Abstract

A 32-year-old male patient was admitted to the hospital with a pulsing mass of the right palm. He was an electrical construction engineer who frequently used a screwdriver. Computed tomography (CT) examination revealed a 22- × 30-mm saccular aneurysm of the right ulnar artery. The ulnar artery aneurysm was resected, and we could perform direct anastomosis of the ulnar artery. The dilated true aneurysm was compatible with a traumatic origin. A postoperative enhanced CT examination showed smooth reconstruction of the palmar arch. An occupational true aneurysm of the ulnar artery could be treated by resection and direct anastomosis.
