Predictors of early adverse events after ascending aortic replacement

Objective. The aim of this study was to identify predictors of adverse events after ascending aortic replacement for the aortic aneurysms in the early postoperative period.Material and Methods. The analysis included 151 patients with ascending aortic aneurysm who underwent non-hemiarch or hemiarch repair. The following adverse outcomes were selected: postoperative delirium, respiratory failure, bleeding, multiple organ dysfunction syndrome, and in-hospital mortality. Predictors of adverse clinical events were identified by constructing uni- and multivariate logistic regression.Results. Significant predictors of early outcomes and mortality after ascending aortic replacement were as follows: female gender, atrial fibrillation, low glomerular filtration rate, chronic obstructive pulmonary disease, aortic root repair, multiple organ dysfunction, duration of cardiac arrest, operation time, and reoperation for bleeding.Conclusions. The risk factors of adverse outcomes after ascending aortic replacement were decreased kidney function, atrial fibrillation, female gender, aortic root repair, and increased duration of cardiac arrest and operation time.
