The VIVO Clinical Study Evaluating the Zilver Vena Venous Stent in the Treatment of Symptomatic Iliofemoral Venous Outflow Obstruction: Three-Year Subgroup Outcomes

Abstract

The Zilver Vena Venous Stent (Cook Medical, Limerick, Ireland) was evaluated under the VIVO Clinical Study (NCT01970007), a prospective, global, single-arm, investigational study, designed to evaluate the safety and effectiveness for the treatment of symptomatic iliofemoral venous outflow obstruction. An understanding of longer-term treatment outcomes is vital; therefore, the purpose of this study update is to report on 3-year patency, clinical improvement, and stent integrity by patient subgroup.
