Abdominal aortic aneurysms (AAAs) are quite common, having a prevalence of 4% to 7% particularly among men and those older than 65 years.1)2) AAAs are potentially fatal when they rupture, with a mortality rate up to 90%.3) Even after emergent operation or endovascular repair, the reported survival rate is only 40%.4) However, the mortality rate can be drastically reduced to 2%–6% when elective repair is performed on unruptured AAAs.5) Since most patients with AAA present without symptoms, the importance of screening should be emphasized. Current guidelines recommend a single ultrasound screening for men and women age 65 years or older who have smoked at least 100 cigarettes.
