Popliteal venous aneurysm, a cause of pulmonary embolism.
Generally, most aneurysms of the venous system are probably congenital and rarely have clinical significance. Popliteal aneurysms are an exception of this rule and are known to be a source of recurrent pulmonary emboli. We present a previously healthy 42 year old man with multiple pulmonary emboli, diagnosed with a high probability lung scan. Venous duplex imaging and magnet resonance imaging showed a mass with connection to the popliteal vein of the left knee, suggesting a venous aneurysm. Despite therapeutic anticoagulation he suffered further pulmonary emboli. After insertion of a temporary vena cava inferior filter aneurysm resection and patch reconstruction of the popliteal vein was performed. By duplex imaging we proved the patency of the popliteal vein after surgical repair. Popliteal venous aneurysms should be kept in mind as possible thromboembolic source in young patients with pulmonary embolism. Our review of the current literature about popliteal venous aneurysms revealed a high rate of pulmonary embolism.
