HINOJOSA, Carlos A. et al. Proactive measurements in the search of aortic aneurysms have an impact in the prevalence. Cir. cir. [online]. 2019, vol.87, n.4, pp.470-476.  Epub 29-Nov-2021. ISSN 2444-054X.  https://doi.org/10.24875/ciru.18000445.

An abdominal aortic aneurysm is defined as a focal dilation greater than 50% of the normal diameter of the vessel. The prevalence in individuals older than 65 years is estimated between the 2 and 8% with a risk of rupture when the diameter >5.5 cm in men and 5 cm in women. The risk increases exponentially with the expansion of this aneurysmal sac, and if the rupture occurs, its mortality can achieve 80%. The pathogenesis and factors associated to the development and progression of this disease remain not fully understood and isolating the aneurysm from the circulation is the main therapeutic goal to eliminate the risk of rupture. Over the last decades, ultrasonographic screening programs have been implemented for its detection. In this article, we review the epidemiology, natural history of aneurysms and the relevance of ultrasonographic screening programs.
