Abstract
Information is incomplete about the rate of expansion of abdominal aortic aneurysms and the risk of rupture in relation to their size. To address these questions, we conducted a population-based study. Of the 370 residents of Rochester, Minn., with an aneurysm initially diagnosed from 1951 through 1984, 181 had the aneurysm documented by ultrasound examination. Among the 103 patients who underwent more than one ultrasound study, the diameter of the aneurysm increased by a median of 0.21 cm per year. Only 24 percent had a rate of expansion of 0.4 cm or more per year.Keywords
