The aim was to determine the optimum rescreening interval for small abdominal aortic aneurysms (AAAs).Data from 12 years of population screening 65-year-old men were analysed and 1121 AAAs (less than 4.0 cm in initial diameter) divided into groups: group 1 (2.6-2.9 cm; n = 625), 2 (3.0-3.4 330) 3 (3.5-3.9 166). Expansion rate cumulative proportions expand over 5.5 cm, or require surgery, rupture calculated.Expansion related diameter: 0.09 per year 1, 0.16 0.32 (P < 0.001). Aneurysms 2.4 cent patients exceeded a diameter required surgery within 5 years; there no ruptures. In 2, aorta but at 2.1 had reached 2.9 surgery. zero. 3, aneurysm 1.2 patients, patient experienced year; 10.5 1.4 ruptured.The appropriate can be determined by screened men. 2.6-2.9 should rescanned years, those 3.0-3.4 3.5-3.9 year.
