Bilateral popliteal artery aneurysms in a young man with Loeys-Dietz syndrome.

Abstract

Loeys-Dietz syndrome is a recently described genetic connective tissue disorder. The syndrome is associated with multiple nonvascular phenotypic anomalies but also aggressive arteriopathy, which has so far principally been shown to cause aortic root dilatation with subsequent dissection and rupture. We report the first ever case of a young man diagnosed with Loeys-Dietz syndrome with asymptomatic large bilateral popliteal artery aneurysms. We have successfully resected these aneurysms and revascularized with synthetic graft.
