Diagnostic dilemma of recurrent pulmonary embolism

Abstract

Popliteal venous aneurysms are rare vascular disorders associated with a high risk of pulmonary embolism. We present the case of a 56-year-old woman hospitalized for a third episode of unprovoked pulmonary embolism. Venous ultrasonography identified a popliteal aneurysm, repeatedly missed by two-point compression venous ultrasonography, which was eventually confirmed by a magnetic resonance examination. Because of its highly symptomatic nature despite optimal anticoagulant treatment, the decision was made to undergo surgery, consisting of aneurysmectomy followed by patch angioplasty. The goal of this paper is to report a rare case of popliteal venous aneurysm and its treatment strategies and postoperative evolution.
