Pivotal Study of Endovenous Stent Placement for Symptomatic Iliofemoral Venous Obstruction.

Background: Chronic venous insufficiency is characterized by inadequate venous return from the lower extremities, which may arise from intravenous obstruction after deep vein thrombosis or from extrinsic venous compression. The purpose of this study was to determine the safety and effectiveness of a dedicated endovenous stent for symptomatic iliofemoral venous obstruction.

Methods: The VIRTUS trial (VIRTUS Safety and Efficacy of the Veniti Vici Venous Stent System [Veniti, Inc] When Used to Treat Clinically Significant Chronic Non-Malignant Obstruction of the Iliofemoral Venous Segment) was a prospective, international, single-arm, pivotal study of endovenous stent placement in patients with symptomatic iliofemoral venous obstruction.
