Intraoperative hemodynamics in prediction of postoperative kidney injury after type a aortic dissection surgery: a retrospective cohort study.

ABSTRACT:

Background

Type A aortic dissection (TAAD) is a severe cardiovascular condition associated with high risks for postoperative complications, particularly renal dysfunction. This study investigated whether intraoperative hypotension and venous congestion are important predictors of postoperative kidney injury and major adverse events.

Methods

We retrospectively analyzed 543 adults undergoing TAAD surgery (2016-2023). Primary outcomes were acute kidney injury (AKI) and acute kidney disease (AKD). Secondary outcomes included death, stroke and composite outcome. Patients were divided into four groups: AKI only, AKD only, AKI and AKD, Non-AKI or AKD. We used restricted cubic spline and multivariate logistic regression models to adjust for confounding factors.
