Endovascular aneurysm repair (EVAR) is a preferred treatment for many abdominal aortic aneurysm patients and an alternative for some who do not qualify for open surgery.
Compared with open AAA repair, minimally invasive EVAR is associated with a significant reduction in mortality, primarily because EVAR does not require exposure of the aorta. EVAR also results in a shorter hospital stay and faster recovery time.
Using the EVAR procedure, the surgeon makes a needle puncture or small incision in one or both of the groin arteries. A thin tube, or catheter, is then inserted and guided to the aneurysm site using X-ray images.
A guide wire and expandable stent graft (fabric-covered wire frame) are then advanced through the thin tube. The stent graft is expanded within the artery, with the wire frame pushing against the healthy portion of the aorta to seal the device in place. Blood is then able to flow through the stent graft. The procedure takes up to three hours to complete and most patients leave the hospital within five days.
