The role of vascular registries in improving the management of abdominal aortic aneurysm.

Treatment of abdominal aortic aneurysm (AAA) is one of the vascular surgical index procedures and an important part of the total workload. Whichever way treated, it typically has high mortality and morbidity. Furthermore, endovascular repair is still a relatively new treatment method and under evolution. Therefore continuous quality control with subsequent outcome analysis, benchmarking, intervention and reassessment are mandatory to achieve high level aneurysm care. Vascular registries are tools for this audit. The aim of this review is to focus on the problems and solutions related to attempts to improve the management of abdominal aortic aneurysm with emphasis on the experience gathered in Finland. This includes great variations in dynamics over time in Southern Finland. To control the influence of patient selection and case-mix, total hospital mortality is emphasized as the most appropriate outcome measure of the level of treatment of ruptured abdominal aortic aneurysm (RAAA). Total aneurysm mortality (including total hospital mortality of RAAA and other AAA surgery) is introduced as an outcome measure of vascular service.
