Setting:

Material:
Reports of all 45,838 necropsies done at the Department of Pathology, Malmö General Hospital 1958-1986.

Abdominal aortic aneurysms were found in 4,300/100,000 men and 2,100/100,000 women. The mean annual age-standardised increase of aortic aneurysmal disease was 4.7% among men and 3.0% among women. The prevalence among men increased rapidly after the age of 55 and reached a peak of 5.9% at the age of 80; that among women increased after the age of 70 and reached a peak of 4.5% above the age of 90 years.
Conclusion:
