Background: Abdominal aortic aneurysm (AAA) is a dilation of the aorta due to aortic wall continues to weaken. If left untreated to withstand the forces of the luminal blood pressure resulting in progressive dilatation and rupture with a mortality of 50 -80%. Objective: This study aimed to assess the efficacy of Endovascular Aortic Repair (EVAR) against Open Surgical Repair (OSR), of infra-renal AAA regarding type of anesthesia, operative time, blood loss, hospital stay and complications. Patient and Methods: From January 2016 to December 2017 in Al-Azhar University Hospital and Military Hospitals in Cairo, we assigned 30 patients with AAA ≥5.5 cm in diameter to undergo either EVAR or OSR; in two equal groups. Patients were followed up for type of anesthesia, operative time, blood loss, hospital stay, morbidity, mortality and complications. Results: Regarding comorbidities, 90% were smokers, 83.3% were diabetic, 76.7% had hypertension (HTN), and 66.7% had ischemic heart disease (IHD). Regarding intra-operative complications, the overall complications rate were 23.3%, with 3.3% had arrythmias, 3.3% had distal emboli, and 16.7% had hemorrhages and received blood transfusion. There was non-significant difference as regards gender, marital status, smoking and Diabetes Mellitus between the 2 groups. Comparative study between the 2 groups revealed significant increase in age, HTN and IHD in EVAR group, compared to OSR group, with significant statistical difference. Comparative study between the 2 groups revealed significant decrease in AAA size and operative time in EVAR group, compared to OSR group, with significant statistical difference. Comparative study between the 2 groups revealed non-significant difference as regards intraoperative complications and blood transfusion. Comparative study between the 2 groups revealed significant decrease in Intensive Care Unit (ICU) and ward stay in EVAR group; compared to OSR group. Conclusion: EVAR compared to conventional surgery has some benefits, such as, lower hospital stay, ICU stay, blood loss, rates of hospital mortality, rates of complications and re-intervention..
