It is inevitable that patients with abdominal aortic aneurysms (AAA) will face life-threatening crises if they do not undergo surgical treatment. In 1995, the first synthetic graft implantation for an AAA patient was performed by Dr. Arthur Voorhees. The knitted Dacron® fabric graft, a polyester polymer, was developed by Dr. Michael DeBakey and associates in Houston and has been an almost ideal graft material to this day. From the 1960s to 1990s, Dacron® and Teflon® grafts have been implanted in AAA patients with a 95% success rate. In 1991, Parodi reported the first successful endovascular AAA repair. The stent graft system is an innovative device designed to be a minimally-invasive treatment option for high risk AAA patients. In the 2000s, endovascular aneurysm repair (EVAR) has been developed as a standard procedure for AAA. Some randomized controlled trials have reported that EVAR had an early survival advantage compared with open repair, however, in long-term outcomes, up to 10 years, there were no advantages of EVAR for aneurysm-related and total mortality compared with open repair. We evaluated the long-term survival and aneurysm related complications for patients who underwent EVAR in our institute.
