Popliteal Venous Aneurysm: A Rare Cause of Recurrent Pulmonary Emboli and Limb Swelling
- Academic Vascular Unit, Hull Royal Infirmary (United Kingdom)
Popliteal venous aneurysm is a rare cause of recurrent pulmonary embolism, although the true incidence of aneurysm is probably underestimated. One-third of patients suffer further embolic events despite therapeutic anticoagulation. We report the case of a 59-year-old male who presented with recurrent PEs over a period of 12 years despite anticoagulation therapy. A thrombophilia screen and abdominal ultrasound were normal at that time. He reattended with recurrent pulmonary emboli, left calf swelling, and a mass in his left popliteal fossa causing limitation of knee movement. Venous duplex and MRI of his popliteal fossa demonstrated a thrombosed true popliteal venous aneurysm with popliteal and superficial femoral vein occlusion. In view of the mass effect we proceeded to surgical excision of his aneurysm after prophylactic placement of an IVC filter. The patient regained normal knee function with intensive inpatient physiotherapy. He has been recommenced on lifelong anticoagulant. The presentation, investigation, and management of the condition are briefly discussed. We suggest that a bilateral lower limb duplex is performed to exclude venous aneurysm in all patients presenting with pulmonary embolism in which an underlying source cannot otherwise be identified and no thrombophilic tendency is detected.
