The prevalence of abdominal aortic aneurysms (AAAs) has been reported to be higher in men than in women. Most prevalence studies (AAA diagnosed by means of autopsy, ultrasound screening, and hospital discharge data) demonstrated the percentage of AAAs diagnosed in women to be 19% to 34% and the percentage diagnosed in men to be 66% to 81%.^1-5 This rate appears to be reliably constant in many Western nations. No cause or causes for the dramatic difference in the prevalence of AAAs between the sexes has been identified.

Risk-factor profiles appear to be similar for both sexes. Age, cigarette smoking, and family history are all reported to have high association with AAA formation.^5,6 Women are usually older than their male counterparts when they undergo AAA repair (Tables 1 and 2). ^1,6-12 Men have a higher association of ischemic coronary artery disease and peripheral aneurysms (usually femoral or popliteal in location), and women have a higher incidence of concomitant aortoiliac occlusive disease.⁶
