Results: An aortic aneurysm is a bulging, dilation or ballooning in the wall of a blood vessel, usually an artery, that is due to weakness or degeneration that develops in a portion of the artery wall. Late graft failure is rare after endovascular aneurysm repair using the Zenith stent graft in a cohort of high-risk patients. The stent graft helps to bypass the area of the aorta weakened by the aneurysm to keep it from rupturing. Stent grafts were oversized 10% to 20% relative to computed tomographic (CT) scan-based diameter measurements. Multicenter trial of the PowerLink bifurcated system for endovascular aortic aneurysm repair. The difference is that the endovascular stent graft is put into place inside the aneurysm without removing any tissue from your aorta, and it does not require open-chest or open-abdominal surgery. Here is how the endovascular stent graft is placed in the aortic aneurysm: Endovascular stent grafting and open surgery grafting are both done to prevent an abdominal aortic aneurysm from rupturing.
