Derivation and validation of a practical risk score for prediction ofmortality after open repair of ruptured abdominal aortic aneurysms in a U.S.regional cohort and comparison to existing scoring systems

摘要

ObjectiveScoring systems for predicting mortality after repair of ruptured abdominal aortic aneurysms (RAAAs) have not been developed or tested in a United States population and may not be accurate in the endovascular era. Using prospectively collected data from the Vascular Study Group of New England (VSGNE), we developed a practical risk score for in-hospital mortality after open repair of RAAAs and compared its performance to that of the Glasgow aneurysm score, Hardman index, Vancouver score, and Edinburg ruptured aneurysm score.
