Poor long-term stability of the Corvita abdominal stentgraft.
BACKGROUND
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.


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


CONCLUSIONS
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.
