This study aimed to assess how the prevalence and growth rates of small medium abdominal aortic aneurysms (AAAs) (3·0-5·4 cm) have changed over time in men aged 65 years, evaluate long-term outcomes whose diameter is 2·6-2·9 cm (subaneurysmal), below standard threshold for most surveillance programmes.The Gloucestershire Aneurysm Screening Programme (GASP) started 1990. Men years with an 2·6-5·4 cm, measured by ultrasonography using inner wall method, were included surveillance. Aortic estimated separately who initially had a subaneurysmal aorta, those or AAA, mixed-effects models.Since 1990, 81 150 ultrasound screening AAA (uptake 80·7 per cent), whom 2795 cm. The screen-detected 3·0 larger decreased from 5·0 cent 1991 1·3 2015. There was no evidence change during this time. Of 57·6 (95 c.i. 54·4 60·7) develop within 5 initial scan, 28·0 (24·2 31·8) large (at least 5·5 15 years.The AAAs has past 25 but remained similar. aorta at age substantial risk developing 80 years.
