Association of Intraoperative Haemodynamic and Postoperative Complications in Type A Aortic Dissection Surgery

Background To determine whether venous congestion is an important predictor of postoperative kidney injury and other adverse events after type A aortic dissection (TAAD). Methods Authors collected data of adults who underwent surgery for TAAD between January 2016 and July 2023. Primary exposures were venous congestion defined by central venous pressure (CVP) and mean arterial pressure (MAP). The primary outcomes were acute kidney injury (AKI) and acute injury disease (AKD). The secondary outcomes encompassed death and stroke. Restricted cubic spline regression model was used to adjust for confounding factors and multiple comparisons.
