To study the outcome of surgery versus ultrasound surveillance for small aortic aneurysms.
Multicentre, random allocation, open trial.
University and general hospitals across the UK.
Patients aged 60-76 years with small asymptomatic abdominal aortic aneurysms (4-5.5 cm in diameter).
The mortality rate, costs, usage of health service resources and quality of life of each treatment will be compared.
From patients randomised to ultrasound surveillance, the natural history of small aneurysms will be determined. The design, methods and progress of this trial are reported here.
