For some patients with abdominal aortic disease and other vascular disease, minimally invasive endovascular techniques may be used. Using advanced radiology and imaging systems, a catheter is inserted through a small incision in your groin or your arm. Next, a tube-shaped, fabric-covered stent is compressed and guided through the catheter up to the damaged portion of the aorta or other blood vessel needing treatment. Once the graft is in place, it is expanded to fit tightly and seal against the wall of the aorta, which creates a new path through which blood can flow. The catheter is removed and the incision site is closed.
