Abstract
Aneurysmal disease of the abdominal aorta was responsible for approximately 16,000 (0.7%) deaths in the United States in 1999. It was the 11th leading cause of death during the same time period for the age range of 65–79 years (National Vital Statistics Reports 2001). The overall incidence is increasing and this is unrelated to the general aging of the population (Cronenwett et al. 2000; Hollier et al. 1992). Males have a four to six times higher prevalence than females and Caucasians are affected more often than other races. Population-based studies vary but generally agree that the overall prevalence in patients >55 years of age is roughly 6.0% in males and 1.5% in females (Pleumeekers et al. 1995; Singh et al. 2001). Differences in the criteria used to define aneurysms may account for the disparity of various reports. Currently, accepted standards classify an abdominal aorta as aneurysmal if an isolated segment of the infrarenal aorta is ≥3.0 cm in diameter or if the diameter of the infrarenal aorta is 1.5× the diameter of the suprarenal aorta (Cronenwett et al. 2000). Aneurysm size is the most important prognostic factor in determining the risk of aneurysm rupture.
