Duplicated Popliteal Venous Aneurysm: Report of a Case

Abstract

A duplicated popliteal venous aneurysm is very rare. We experienced this rare entity in a 53-year-old male. He complained swelling of his left popliteal fossa. Contrast enhanced computed tomography revealed both of 30×33 mm and 27×30 mm saccular venous aneurysms without thrombus formation at the left proximal popliteal vein. No pulmonary thromboembolism was detected. He was successfully treated by tangential aneurysmectomy with lateral venorrhaphy. The histopathological examination revealed disappearance of the medial smooth muscle layer and intimal hypertrophy at caudal part of the venous aneurysm. On the other hand, the medial muscle layer was hypertrophic at the cephalad. After aneurysmectomy, the popliteal vein was patent one year later. He also had a 20 mm fusiform venous aneurysm at the opposite side, and a long term follow-up is mandatory.
