A popliteal venous aneurysm with deep venous thrombosis in the contralateral calf: report of a case

Abstract

Although a popliteal venous aneurysm is a rare entity, it is an important cause of pulmonary embolism (PE), which is occasionally life-threatening. We herein report a case of a popliteal venous aneurysm with deep venous thrombosis (DVT) in the contralateral calf. A 65-year-old male, who presented with sudden onset palpitation and dyspnea, was transferred to our hospital. Enhanced computed tomography revealed PE and a venous aneurysm of the left popliteal vein. The popliteal venous aneurysm was saccular and had an intramural thrombus. Furthermore, duplex scanning detected DVT in the contralateral calf. The patient underwent a tangential aneurysmectomy with lateral venorraphy. The surgery and postoperative course were uneventful. The PE and calf DVT disappeared with perioperative anticoagulant therapy. It is recommended that, in the treatment of popliteal venous aneurysms, special attention should be given to the condition of the venous vessels of the contralateral leg, because this can influence the therapeutic strategy.
