Aneurysm resection interposed with a spiral saphenous vein graft in a patient with a popliteal venous aneurysm with thrombosis.

We describe the case of a 46-year-old man with pulmonary thromboembolism caused by a popliteal venous aneurysm with thrombosis. The aneurysm was fusiform and partially saccular with a thrombus, and the caliber of the native popliteal vein was large. Tangential aneurysmectomy with lateral venorrhaphy was difficult because of the aneurysm type, and graft interposition was required because of the large venous diameter of the anastomosis site. The patient underwent aneurysm resection interposed with a spiral saphenous vein graft. The postoperative course was uneventful, and the graft was patent at 1 year after surgery.
