Answer

In autopsy studies, the frequency rate of AAA ranges from 0.5% to 3.2%. In a large US Veterans Affairs screening study, the prevalence was 1.4%. [2] The likelihood of development ranges from 3 to 117 cases per 100,000 person-years.

Ruptured AAA is the 13th-leading cause of death in the United States, causing an estimated 15,000 deaths per year. The frequency of rupture is 4.4 cases per 100,000 persons. The reported incidence of rupture ranges from 1 to 21 cases per 100,000 person-years. Despite increased survival following diagnosis, incidence and crude mortality seem to be increasing.
