	Introduction

 
Most manifestations of cardiovascular disease are more common in men than in women. However, cardiovascular disease is the most common cause of death in women worldwide.¹ Coronary heart disease in women has a worse outcome than in men, and this has attracted considerable attention in recent years, with calls for more gender-specific research.^1,2 Abdominal aortic aneurysms (AAAs) also are less common in women than in men, and, as with coronary heart disease, there is evidence that women with AAA also have a worse prognosis. The present review addresses the epidemiology, development, natural history, management, and outcomes of AAA in women.

	Prevalence and Incidence

 
When the definition of a maximum external diameter 3 cm is used, the prevalence of AAA is up to 6 times greater in men than in women.^3,4 In a community-based screening study of the older population, the prevalence of AAA was 1.3% in women compared with 7.6% in men.⁴ Similarly, the ratio of men to women in surgical series is 5:1.^5–7 Because of the relatively low prevalence, women were excluded from the large trials of screening for AAA.^8–10 The prevalence in women from families with a strong history of AAA may be as high as 8.3%, and these women should be offered screening.¹¹ Modeling studies have indicated that screening for AAA in women could be cost-effective because the rupture rate appears to be much higher in women than in men.¹²

The incidence of AAA has continued to rise over the last 4 decades.^13–16 Initially, a similar pattern was seen in . . . [Full Text of this Article]
