Fct. Smith et al., ULTRASONOGRAPHIC SCREENING FOR ABDOMINAL AORTIC-ANEURYSM IN AN URBAN-COMMUNITY, British Journal of Surgery, 80(11), 1993, pp. 1406-1409
As part of the Birmingham Community Aneurysm Screening Project, 3500 m
en aged 65 - 75 years from 20 urban general practices were invited for
aortic ultrasonographic screening at their own general practitioner '
s surgery; 2669 (76.3 per cent) attended. Compliance rates varied betw
een catchment areas, from 52.1 per cent for inner-city areas to 89.6 p
er cent for suburbs. Successful aortic imaging was achieved in 97.3 pe
r cent of scans. Aortic diameter > 29 mm occurred in 219 patients (8.4
per cent) and 79 (3.0 per cent) with a diameter > 40 mm were referred
for vascular surgical assessment; 140 patients with an aortic diamete
r of 29-40 mm are currently undergoing follow-up by serial ultrasonogr
aphic examinations at intervals of 3 months at their doctor's surgery;
Risk factor analysis revealed ischaemic heart disease in 21.9 per cen
t of men with aneurysm, compared with 11.6 per cent in those without (
P < 0.001); 18.3 per cent of men with aneurysm had had a previous myoc
ardial infarction and 13.2 per cent had peripheral vascular disease, c
ompared with 7.4 per cent (P < 0.001) and 8.0 per cent (P < 0.01) resp
ectively of those without. No association was found between aneurysm a
nd hypertension or diabetes. Community-based aortic screening is an in
expensive, effective method of diagnosis of aneurysm, with high compli
ance from the at-risk cohort of nn urban population. Such screening pr
ogrammes may help to reduce the mortality rate from aortic aneurysm ru
pture.
