What is the stent graft endovascular treatment of AAAs?
Instead of the direct resection of the aneurysm, a stent graft is placed inside the aneurysm. The device is supported by a wire framework, in order to avoid collapse. The stent grafts usually come in different sizes, so that a tight fit can be achieved at the proximal and distal ends of the aneurysm. This device is introduced through a small incision in both groins. The entire procedure is performed either in the operating room or radiologic suite. A successful outcome means that the arterial pressure is eliminated from the aneurismal wall by the stent graft. Thousands of patients have now been treated by this procedure in the US and around the world. The FDA has recently approved two different stent grafts for treating AAA’s and more will be released in the future.
