Implication

Increased AAA diagnoses with high emergency mortality support screening; leaves open optimal strategies in observational data.

Key Points

To examine the epidemiological trends, rupture characteristics, and surgical outcomes of abdominal aortic aneurysms over an 11-year interval.
Reviewed all abdominal aortic aneurysm cases (N=1237) presenting to hospitals and coroner services between January 1971 and December 1981 in Western Australia.
Calculated age- and sex-standardized incidence rates for populations over 55 years of age and compared mortality across elective versus emergency surgical resections.
Standardized diagnosis rates increased from 74.8 to 117.2 per 100,000 in men over 55 (a 56.7% increase) and from 17.5 to 33.9 per 100,000 in women over 55 (a 93.7% increase).
Among 478 surgical repairs, elective resections showed a 4.0% fatality rate (n=225) compared to a 31.2% fatality rate for emergency repairs (n=253).
Coroner autopsies identified 123 sudden rupture deaths without prior aneurysm diagnosis, with rupture presentations demonstrating potential seasonal clustering during colder weather.

The study highlights a significant increase in the prevalence of diagnosed abdominal aortic aneurysms and demonstrates a markedly higher fatality rate for emergency versus elective surgical repair.
