ABSTRACT
Venous disorders have a high prevalence and require approximately 1% of health budgets of industrialized countries. The postthrombotic syndrome (PTS) is defined by subjective symptoms and morphologic trophical skin changes following deep venous thrombosis. Prevention of venous thromboembolism in risk situations, easy availability of diagnostic tools (D-dimers, colour-coded duplex sonography) and early detection of deep venous thrombosis, as well as immediate therapeutic anticoagulation along with leg compression during the acute phase and over a two year period of time significantly reduce the incidence of PTS. Chronic venous insufficiency (CVI) includes trophical skin and soft tissue pathologies of the lower leg due to venous hypertension in the distal venous system of the lower extremity. Roughly, two main causes can be distinguished. (A) Deep venous insufficiency (A1 in postthrombotic syndrome; A2 in primary deep venous insufficiency) and (B) superficial venous reflux, usually varicose veins. Compression therapy, surgical ablation of superficial venous reflux, and tangential ablation with split skin graft (shave treatment) of refractory venous ulcers are the mainstays in the treatment of CVI.

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.
