Impact of postoperative acute kidney injury on short-term outcomes of patients with Bentall surgery for any reason.

BACKGROUND

Acute kidney injury (AKI) after cardiac surgery is a well-known risk factor for increased postoperative mortality and morbidity. The effect of postoperative developed AKI on postoperative outcomes in patients after Bentall procedure has been incompletely investigated. The present study was dedicated to assessing the impact of postoperative AKI on morbidity and 30-day mortality in this specific cohort.

METHODS

In a retrospective observational study, we investigated 249 patients undergoing Bentall procedure from January 2014 to March 2018 at the University Hospital of Cologne, Germany. After excluding patients with preoperative renal impairment, patients were divided into an AKI group (

RESULTS

Mortality during ICU and hospital stay, as well as 30-day mortality, was significantly higher in the AKI group (all

CONCLUSION

Patients undergoing Bentall surgery who postoperatively developed AKI showed significantly higher morbidity and mortality. AKI points out to be an early predictor for poor outcomes. Thus, as a consequence, patients with postoperatively developed AKI should be highly monitored for immediate intervention.
