Off-pump coronary artery bypass surgery and the kidney.

摘要

In this issue, Nigwekar et al examined, through a systematic review and meta-analysis of randomized and observational trials, the impact of off-pump surgery compared with conventional coronary artery bypass grafting (CABG) surgery on kidney function. In this article, we discuss the rationale for off-pump versus on-pump bypass surgery and provide an overview of the evidence that off-pump surgery may improve a number of clinical outcomes, including kidney function. We also discuss clinical implications for patients at risk of decreased kidney function or those with kidney failure treated by dialysis who present for CABG.
