Reason: This article concluded that selective renal artery perfusion at adequate volume and pressure protects renal function during thoracoabdominal aneurysm repair. The editors have retracted this article at the request of the authors because of errors identified during a subsequent analysis of the data. These errors included selective patient inclusion and varying definitions that led to a systematic bias in favor of the conclusion. As a result of these errors, the validity of the published conclusions cannot be sustained. Unfortunately, not all of the primary data were still available to potentially correct these errors. Readers should disregard any conclusions reached in this article about the value of selective renal artery perfusion.
