This surgery repairs a bulge in a weakened section of the aorta that passes through the abdomen. A surgeon inserts a tube, called a stent graft, and bridges two healthy sections of the aorta, bypassing the aneurysm. In a traditional, open surgery the doctor makes a large incision in the chest or abdomen, removes the aneurysm and replaces the damaged portion with a stent graft. This procedure can also be performed in a cath lab or interventional radiology suite. In this procedure a small incision is made in the groin area to access a blood vessel and catheters are guided to the aneurysm to deploy the graft device. The surgeons uses live x-ray images of the blood vessels to guide the catheter to the right location.
