Predictors of failure to rescue after fenestrated-branched endovascular aortic repair of thoracoabdominal aortic aneurysms.

Objective: Failure to rescue (FTR), defined as mortality due to failure in responding to in-hospital complications, is an important quality indicator. This study aimed to assess incidence and predictors for FTR among centers performing fenestrated-branched endovascular aortic repair (FB-EVAR) of thoracoabdominal aortic aneurysms (TAAA).

Methods: Consecutive patients treated by FB-EVAR for TAAAs between 2005 and 2022 in 27 centers of the International Multicenter Aortic Research Group were analyzed.
