The Value of a Nationwide Vascular Registry in Understanding Contemporary Time Trends of Abdominal Aortic Aneurysm Repair

Abstract

Nationwide vascular registries offer rapid feed-back in an environment of fast new technical development, as is the case with the treatment of abdominal aortic aneurysm (AAA). Furthermore, they offer an opportunity to study non-selected, population-based data. The aim of this review was to analyze time-trends in published papers from nationwide registries on AAA-repair. In contrast to several US reports, an increased rate of intact AAA repair, associated with the introduction of endovascular repair, was reported in a recent publication based on the Swedish Vascular Registry (Swedvasc). The rate of ruptured abdominal aortic aneurysm (rAAA) repair is stable in most reports, while some report a decreasing incidence. Most nationwide studies report a reducing mortality over time after intact AAA repair, while time trends on the mortality after ruptured AAA repair are more heterogenic.
