Stent Grafting for Aortoiliac Occlusive Disease: Review of the VBX FLEX Study

Abstract

Endovascular treatment has become an accepted method in the treatment of aortoiliac occlusive disease. Bare metal stents have been used in the treatment of aortoiliac disease since the early 1990s. More recently, the use of covered stent grafts in the aortoiliac segment has shown clinical benefit in terms of patency, freedom from reintervention and quality of life. The VBX FLEX study evaluated the safety and efficacy of the Gore VBX stent graft for use in the aortoiliac segment. The early and mid-term data on the Gore VBX stent graft have shown it to be a safe device for use in the treatment of aortoiliac occlusive disease. This review examines the use of stents in aortoiliac occlusive disease with specific focus on the VBX FLEX Study.
