What is an abdominal aortic aneurysm (AAA) repair?

Abdominal aortic aneurysm (AAA) repair is a procedure used to treat an aneurysm (abnormal enlargement) of the abdominal aorta. Repair of an abdominal aortic aneurysm may be performed surgically through an open incision or in a minimally invasive procedure called endovascular aneurysm repair (EVAR).

To repair an aneurysm in the abdominal aorta, the portion of the aorta below the kidneys, vascular surgeons make an incision in the abdomen, clamp the aorta to reduce blood flow, then open the aneurysm and sew in a graft within the aneurysm sac to reinforce the affected vessel walls. The graft is a woven tube made of a synthetic material. Blood flow is contained inside the graft alleviating pressure on the weakened walls of the aneurysm and allowing normal blood flow to the legs and other organs.
