Abstract
Upper-extremity arterial aneurysms are uncommom lesions, and are usually pseudoaneurysms. Most pseudoaneurysm are associated with trauma. We report two cases of nontraumatic pseudoaneurysm of ulnar artery, which were treated successfully with excision of the aneurysm. Case 1: A 66-year-old male presented with a painless mass in his right forearm. Arterial duplex imaging demonstrated a 20-mm diameter mass arising from the ulnar artery. The excision of the aneurysm was performed, and postoperatively, he had no ischemic complications. Case 2: A 53-year-old woman presented with a painless mass in her left forearm. The laboratory findings revealed eosinophilia. Computed tomography showed a 30 mm diameter pseudoaneurysm of the ulnar artery. The aneurysm was totally resected, and diagnosed histologically as angiolymphoid hyperplasia with eosinophilia. Postoperatively, the eosinophilia gradually returned to within the normal range. The operative resection of pseudoaneurysm of upper extremity should be performed, and revascularization can be performed selectively.
