RESUMEN
Chronic renal failure (CRF) is related to cardiac diseases. Cardiac surgery is also related to postoperative acute kidney injury (AKI). It means heart and kidney have close relationship. We analyzed recent published data to understand how to manage CRF patients undergoing cardiovascular surgeries. We compared endovascular surgery and open procedure for aortic aneurysm, especially about contrast media-related renal damage, On or Off CABG or PCI for ischemic heart disease. We also discussed the relation between cardiopulmonary bypass and AKI and the risk factors causing AKI after CPB. Finally, we discussed prevention and treatment options of CPB related AKI, including furosemide, hANP mannitol, and statin. Published evidence in this area is still insufficient, but many studies are still carried out focusing on postoperative AKI. In the future we may be able to find the best answer for managing CRF patients undergoing cardiovascular surgeries.
