Endovascular aortic repair (EVAR), also called an endovascular stent graft, is a surgical procedure used to treat aortic aneurysms.

You may be put under local or general anesthesia, depending on the location and severity of your aneurysm.

Your vascular surgeon makes an incision in the groin area to access the leg (femoral) artery.

Using a catheter, contrast dye, and X-ray imaging, he or she will guide a metal mesh tub, called a stent graft, to the aneurysm site, where it expands to fit snugly against the artery’s walls.

Because the stent graft is stronger than the artery’s walls, it allows blood to flow through the artery without causing more damage to or rupturing the aneurysm.
