Endovascular repair of an abdominal aortic aneurysm is performed by inserting a catheter that contains an endovascular stent graft into the arteries of the groin. The catheter is advanced and placed inside the aneurysm. The graft is then expanded and held in place with metal hooks and by the pressure that the graft exerts against the wall of the aorta. X-ray guidance is used to properly position the graft within the aneurysm.

The purpose of the endovascular stent graft is to exclude blood flow to the aneurysm. When the graft is in the correct position, blood flow is through the graft and the aneurysm will no longer enlarge in size.
The procedure usually takes about two to three hours.
There is some risk with every operation. The risk varies with each person, depending on the extent of the aneurysm disease and the type of procedure. Although rare, bleeding, blockage of the bypass graft, infection, heart problems, kidney failure, a reaction to the contrast dye, bowel ischemia and spinal cord ischemia may occur after surgery. These problems may require more surgery. Your surgeon will discuss the benefits and risks of your surgery.
Surgery is sometimes postponed due to another patient needing emergency surgery, or if you develop a fever, sore throat or cold. You are told of any delay as soon as possible. Surgery is postponed only when absolutely necessary.
The Center for Vascular Disease at the Bluhm Cardiovascular Institute is affiliated with Northwestern University Medical School, which is involved in a variety of research studies. If you are asked to take part in one of these studies, the decision is yours. Please ask your doctor if you have any questions.
