The Endurant stent graft for endovascular aneurysm repair

Endovascular aneurysm repair (EVAR) has become an established therapy for many patients with abdominal aortic aneurysms. This minimally invasive procedure has lower operative mortality and similar long-term survival rates compared to open surgical treatment. However, several patients are still unsuitable for EVAR because of their aneurysm neck or iliac artery anatomy, and secondly, re-intervention rates are higher after EVAR than after open aneurysm exclusion. Current challenges in the development of new stent grafts are to make more patients eligible for EVAR, including patients with challenging anatomy, and to decrease re-intervention rates. A range of different stent grafts now exist, and in the search for a device with the widest applicability and the least complications, the Endurant stent graft is a recent addition. This device offers wider inclusion criteria. Despite this, first results show comparable complication rates compared to other stent grafts, and long-term follow-up studies are underway.
