First, having a complete diagnostic assessment (usually via MRI and angiography) of pattern, size and location of aortic aneurysm before the surgery in order to choose the most appropriate stent graft for the patients. Using x-rays to see the exact location of the aneurysm, the surgeon will guide the delivery catheter through the large vessel in your thigh (iliac vessel) to the aneurysm site in your abdomen. The stent graft is slowly released from the delivery catheter into the aorta.

As the stent graft is released, it expands to the proper size so that it fits into the aorta both above and below the aneurysm. In this way, there is no active blood flow in aneurysm and the risk of rupture has been reduced.
