Aneurysms of the upper extremity

Thirty aneurysms in the upper extremity in 28 patients over the last 10 years are reviewed. Analysis showed that false aneurysms develop from penetrating trauma, while true aneurysms tend to arise in parts of the arterial tree exposed to blunt trauma. Penetrating injury to vessels should be thoroughly explored and repaired. Arterial aneurysm should be included in the differential diagnosis of masses in the upper extremity, especially after trauma. Three-phase radionuclide scanning is a useful tool for evaluating lesions of the distal arterial tree. When an aneurysm is suspected, early treatment is advised. Treatment options of resection and ligation versus reconstitution of vessel flow should be based on preoperative and intraoperative evaluation of circulatory status.
