              Abdominal aortic aneurysm (AAA) is a localized dilatation of the abdominal aorta that the size is 1.5 times or more than the normal size, or that with 3 cm. diameter. AAA based on the location of proximal end of aneurysm is classified into three main types, which are infrarenal, juxtarenal and suprarenal types. There are two types of AAA surgery nowadays: Open abdominal aortic repair and endovascular aortic aneurysm repair (EVAR). Indications for surgery are aneurysm size is ≥ 5.5 cm. in male and ≥ 5.0 cm. in female or rapid enlarging aneurysm more than 1 cm. per year or is the saccular aneurysm or is the symptomatic AAA. There are many types of EVAR treatments recently, each type has risk and benefit. Selection of EVAR designs depends on the patient’s condition and anatomy of the aorta. Surveillance of the patient after EVAR procedure is the most important because the complication may happen anytime. Early detection may lead to better outcomes.
