[Popliteal vein aneurysms]

We report our experience with four cases of popliteal vein aneurysms treated over the last five years. The pathogenesis of these rare lesions is unknown. The inner wall of true venous aneurysms exhibit a reduced number of muscle fibers and fragmented elastic fibers replaced by fibrous tissue. The most dangerous risk related to popliteal vein aneurysm is pulmonary embolism. Diagnosis is based on phlebography and duplex Doppler findings. Surgery can provide cure and prevent complications. We treated our four patients with an asymptomatic aneurysm of the popliteal vein with aneurysmectomy using an atraumatic clamp and direct suture. Oral anticoagulants were given and elastic compression was maintained for six months, with satisfactory results.
