The current false lumen endograft and clinical experience for false lumen occlusion in chronic aortic dissection.

Abstract

False lumen management of chronic aortic dissections has evolved during the past decade. Thoracic endovascular aortic repair (TEVAR) continues to be the mainstay of endovascular dissection treatment and relies on the adequate sealing of the proximal entry tear. However, TEVAR alone often fails to achieve aortic remodeling due to persistent distal retrograde perfusion of the false lumen with continuous aneurysmatic degeneration. Endovascular occlusion of this retrograde false lumen flow using dedicated false lumen endografts (FLEs), has therefore gained popularity. Similar to other endografts, FLE design has evolved from extra-large vascular plug through physician modified version, to different iterations of a custom-made, self-occluding endografts. This manuscript summarizes the evolution of false lumen occluders, characteristics of the last generation of the device and currently available literature clinical experience.
