[Stent grafting for abdominal aortic aneurysm repair]

Stent grafting for abdominal aortic aneurysm repair uses three types of stent graft: the aorto-aortic straight type; aorto-uniiliac tapered type; and aorto-biiliac bifurcated type. Stent grafting for abdominal aortic aneurysm repair is performed in the operating room under X-ray fluoroscopy with digital subtraction angiography. Intraoperative angiography marks the bilateral renal arteries, bifurcation of the terminal aorta, and the bilateral internal and external iliac arteries. An X-ray fluoroscope is fixed until the completion of all procedures. The pull-through technique, in which a guidewire extends from the brachial artery to the external iliac artery, yields a 100% deployment success rate, and safety and reliability for the second graft deployment or balloon dilatation of the stent graft. The guidewire is removed after all procedures have been completed.
