Abstract
In the United States, the incidence of Abdominal Aortic Aneurysm (AAA) is 2-4% in the adult population. AAA is 4-6 times more common in male siblings of known patients, with a risk of 20-30% to develop. Rupture of the AAA occurs in 1-3% of men aged 65 or more, the mortality is 70-95%. Endovascular repair first became practical in the 1990s and although it is now an established alternative to open repair, its role is yet to be clearly defined. It is generally indicated in older, high-risk patients or patients unfit for open repair. However, endovascular repair is feasible for only a proportion of AAAs, depending on the morphology of the aneurysm. The findings of two studies EVAR1 and OVER have shown that patients receiving elective endovascular repair of abdominal aortic aneurysm have a better short-term prognosis than patients receiving more-invasive conventional open repair Thirty patients with infrarenal abdominal aortic aneurysm indicated for repair according to the guidelines of The Society for Vascular Surgery and the International Society for Cardiovascular Surgery guidelines for the repair of AAA and meet the criteria for endovascular repair will be selected to undergo endovascular repair of abdominal aortic aneurysm (EVAR).To assess the midterm outcome and efficiency of endovascular repair of infra renal abdominal aortic aneurysm Our study showed that over 3-5 years follow up after endovascular repair of AAA, re-intervention rate for all types of endoleak is 10% (3 patients). from them 3.33% (1 patient) for type I endoleak and 6.66% (2 patients) for type 2 endoleak. Although it has small number of patients, 3-5 years midterm outcome showed low morbidity and mortality for EVAR for infrarenal AAA patients suitable for the treatment
