Elective Abdominal Aortic Aneurism - Open Versus Endovascular Repair

Assistance Publique - Hôpitaux de Paris306 enrolled

Overview

Abdominal aortic aneurysm (AAA) is a life threatening disease. There is a consensus to propose surgical repair in patients with a reasonable operative risk when the AAA exceeds 5 cm in diameter. The aim of the study is to compare the mortality and the occurrence of severe general, vascular and local complications in two groups of patients treated by either by open surgery or by EVAR (EndoVascular Aneurysm Repair). The main outcome criteria and the secondary endpoint are respectively the survival without severe complications and minor morbidity.

Interventions

Endovascular repair (with endograft)PROCEDURE

An endovascular stent graft is a tube composed of fabric supported by a metal mesh called a stent. It can be used for a variety of conditions involving the blood vessels, but most commonly to reinforce a weak spot in an artery called an aneurysm. Over time, blood pressure and other factors can cause this weak area to bulge like a balloon and eventually enlarge and rupture. The stent graft seals tightly with your artery above and below the aneurysm. The graft is stronger than the weakened artery and allows blood to pass through it without pushing on the bulge. Physicians typically use endovascular stent grafting to treat abdominal aortic aneurysms (AAAs).

Open repairPROCEDURE

Conventional repair consist in open repair. Different types of surgery can be done : minimal incision aortic surgery (MIAS), transperitoneal approach (TPA), retroperitoneal repair, or conventional median laparotomy.
