Overview
The incidence of aortic aneurysm increases with age; the median age at diagnosis is 69 years.
Epidemiology and Demographics
In the United States alone 15,000 people die yearly due to aortic aneurysms and it is the 13th leading cause of death. 1-2% of the population may have aortic aneurysms and prevalence rises up to 10% in older age groups. The disease varies according to where it takes place. In the thorax, the aortic arch is the less affected segment (10%) and the most common is the ascending aorta (50%). Regarding abdominal aneurysms, the infrarenal segment aortic aneurysms are three times more prevalent than the aortic aneurysms and dissections.[1]
Regarding other factors as age, abdominal aortic aneurysms usually present 10 years later than thoracic aortic aneurysms. Both lesions are more present in men, but the proportion is much higher regarding abdominal aortic aneurysms (6:1 male:female ratio) in comparison to thoracic ones.[1]
Abdominal aortic aneurysms also affect patients differently regarding race, as they are more prevalent among whites than blacks, asians and hispanics. It also seems to be declining in prevalence as evidenced by a Swedish study that found out a 2% prevalence of abdominal aortic aneurysms in comparison to earlier studies which reported 4-8%, probably due to risk-factor modification.
