Surgical Repair for Popliteal Venous Aneurysm Causing Severe or Recurrent Pulmonary Thromboembolism: Three Case Reports

Poplitealvenous aneurysms (PVA) are associated with deep venous thrombosis and recurrentpulmonary thromboembolism (PE). We report three cases of PVA. In all three patients the first sign of PVA was acute PE; in one case, the PE was recurrent. Computed tomography and duplex ultrasonography revealed not only PE but also popliteal venous dilatation with thrombus. Surgical reconstruction was performed in each case after treatment for PE. No postoperative complications occurred, including recurrent PE. Surgical repair of PVA is safe and is a recommended treatment.
