P. Crow et al., A single normal ultrasonographic scan at age 65 years rules out significant aneurysm disease for life in men, BR J SURG, 88(7), 2001, pp. 941-944
Backgrounds: Screening for abdominal aortic aneurysm (AAA) has been carried
out in Gloucestershire since 1990. All men in the county are offered aorti
c ultrasonography in their 65th year. Men with an aortic diameter of less t
han 26 mm are considered 'normal' and no follow-up is arranged. The aim of
this study was to ascertain if men with 'normal' aortic diameters at age 65
years ever develop a clinically significant aneurysm.
Methods: A cohort study was performed on 223 65-year-old men who had an aor
ta of less than 26 mm in diameter in 1988. These men had repeat ultrasonogr
aphy in 1993 and 2000. The causes of death in men who died during this inte
rval were investigated.
Results: Eight men were lost to follow-up. As far as it was possible to asc
ertain, none of the 86 men who died over the 12-year interval did so from r
uptured AAA. There was no clinically significant increase in mean aortic di
ameter in the remaining 129 men who had three serial ultrasonographic scans
over the 12-year interval.
Conclusion: A single, 'normal' ultrasound scan at age 65 years effectively
rules out the risk of clinically significant aneurysm disease for life in m
en.
