Methods From June 2007 to March 2013, 7 patients with abdominal aortic aneurysm underwent endovascular aortic aneurysm repair using the Powerlink unibody stent graft , Which were deployed sitting on the anatomical abdominal aortic bifurcation (termed anatomical fixation ).the abdomonal contrast-enhanced CT eximinations of 7 cases were performed before discharge and 1month , 6months , 1year after discharge and annually. Results 7 cases were deployed successfully. Proximal cuff was implanted in one case and distal limb extention was used in 4 cases, one case received distal limb bare stent. No interoperative complication ocurred. During the follow-up time with 3- 68(median, 36 ) months., there were no endoleak , stent graft migration and aneurysm rupture. Conclusion The anatomical fixation of unibody stent graft was safe and effective in treating abdominal aortic aneurysm . 【Key words】 Endovascular aortic repair; Aorti
