Poor long-term stability of the Corvita abdominal stentgraft

Eur J Vasc Endovasc Surg. 2014 Feb;47(2):160-3. doi: 10.1016/j.ejvs.2013.10.010. Epub 2013 Oct 22.

Abstract

Introduction: The endovascular treatment of abdominal aortic aneurysms was introduced in the early 1990s, with different generations of devices using various options for either the stent skeleton or the membrane.

Report: Corvita generated one of these devices using braided stainless steel and a porous spun polycarbonate urethane membrane.

Discussion: In this report, we describe a case involving Corvita stentgraft explantation for complete aneurysm reperfusion after 13 years, demonstrating major degradation of the polyurethane membrane.

Keywords: Corvita; Degradation; EVAR; Polyurethane.
