摘要
Background: Between 1951 and 1995 there was a steady increase in age-standardised deaths from all aortic aneurysms in men, from 2 to 56 per 100,000 population in England & Wales, supporting an increase in incidence. More recently, evidence from Sweden and elsewhere suggests that now the incidence of abdominal aortic aneurysm (AAA) may be declining. Methods: National statistics for hospital admissions and deaths from AAA, after population age-standardisation, were used to investigate current trends in England & Wales and Scotland. Results: Between 1997 and 2009 there has been a reduction in age-adjusted mortality from AAA from 40.4 to 25.7 per 100,000 population for England & Wales and from 30.1 to 20.8 per 100,000 population in Scotland. The decrease in mortality was more marked for men than women. Mortality decreased more than 2-fold in those <75 years versus 25% only in those >75 years. During this same time period the elective hospital admissions for AAA repair have only increased in the population >75 years. Conclusions: These data suggest that the age at which clinically-relevant aneurysms present has increased by 5-10 years and that incidence of clinically-relevant AAA in men in England & Wales and Scotland is declining rapidly. The reasons for this are unclear. (C) 2011 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.
