Abdominal aneurysm: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Abdominal aortic aneurysms result from arteriosclerosis, hypertension, congenital weakening, cystic medial necrosis, trauma, syphilis, and other infections. In children, this disorder can result from blunt abdominal injury or Marfan syndrome. These aneurysms develop slowly. First, a focal weakness in the muscular layer of the aorta (tunica media), due to degenerative changes, allows the inner layer (tunica intima) and outer layer (tunica adventitia) to stretch outward. Blood pressure within the aorta progressively weakens the vessel walls and enlarges the aneurysm.

This disorder is four times more common in men than in women and is most prevalent in whites ages 40 to 70. Less than 50% of people with a ruptured abdominal aortic aneurysm survive.

About prevalence and incidence statistics:

The term 'prevalence' of Aneurysm usually refers to the estimated population of people who are managing Aneurysm at any given time. The term 'incidence' of Aneurysm refers to the annual diagnosis rate, or the number of new cases of Aneurysm diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
