Background: Rupture of an unsuspected abdominal aortic aneurysm is a major
cause of death in men over the age of 65 years. A significant reduction in
deaths is likely to result only from higher rites of detection and increase
d numbers of elective aneurysm repairs. Screening of men reaching the age o
f 65 pears has been taking place in the county of Gloucestershire, UK since
1990 and the aim of this study was to investigate any change in the mortal
ity rate from aortic aneurysm in the screened portion of the population.
Methods: Total number of deaths from all aortic aneurysm-related causes in
the county's population was calculated from hospital and post-mortem record
s, together with computerized death certificate records, for the years 1994
-1998. The overall number of aneurysm-related deaths in men aged 65-73 year
s, who have been progressively influenced by the screening programme, was c
ompared with that for men of all other ages.
Results: The total number of aneurysm-related deaths in men aged 65-73 year
s decreased progressively year by year between 1994 and 1998; this reductio
n is highly statistically significant (P < 0.001). No such change was obser
ved in the unscreened part of the population.
Conclusion: Screening for asymptomatic abdominal aortic aneurysm results in
a significant reduction in numbers of deaths from all aneurysm-related cau
ses in the screened portion of the male population.
