In a ten-year review (1978 to 1988), ten ulnar artery aneurysms in nine male patients were studied. Blunt trauma led to 70%, penetrating trauma to 20%, and 10% had no history of trauma. Three cases were seen as asymptomatic palmar masses with brief antecedent histories of 4 weeks or less. Seven patients with aneurysms had persistent vascular hand symptoms for 6 weeks or longer. All seven symptomatic lesions proved to be sources of emboli. Diagnostic arteriography was done in all cases. Intraoperative digital plethysmography aided in operative decisions regarding the necessity for microvascular reconstruction. Five aneurysms were resected with end-to-end ulnar artery microvascular repairs, four resected without repair, and a single case treated with long-term anticoagulants. Follow-up, averaging 40 months, showed uniform improvement in vascular symptoms, with no loss of jeopardized tissues. Ulnar artery aneurysms, well studied preoperatively and intraoperatively, can be treated successfully with selective microvascular reconstruction.
