Abstract
Background The epidemiology and management of abdominal aortic aneurysms (AAAs) has changed drastically in the past decades, with implementation of nationwide screening programs, introduction of endovascular repair (EVAR), and reduced prevalence of the disease. This report aims to assess recent trends in AAA repair epidemiology in Sweden in this context. Methods Primary AAA repairs registered in the nationwide Swedish Vascular Registry (Swedvasc) 1994–2014 were analyzed regarding patient characteristics, repair incidence, technique, and outcome. Four time periods were compared: 1994–1999, 2000–2004, 2005–2009, and 2010–2014. Result The incidence of intact AAA repair increased (18.4/100,000 1994–1999, 27.3/100,000 2010–2014, p p p p p Conclusions For the first time, a halt in intact AAA repair workload could be identified. This trend-break occurred despite continued increase in treatment of octogenarians and screening-detected aneurysms. Additionally, the ruptured AAA repair incidence continued to decrease. These findings, together with the sustained improvement in survival after AAA repair, may have important impact on planning of vascular surgical services.
