Early postoperative acute kidney injury prediction in patients with acute type A aortic dissection.

ABSTRACT: Acute kidney injury (AKI) is a frequent and serious complication following surgery for acute type A aortic dissection (AAD), often leading to delayed treatment and poor outcomes. This multicenter study developed and validated a predictive nomogram for early postoperative AKI in 1,211 AAD patients. Using logistic regression, independent risk factors were identified: age, hypertension, preoperative shock, and cardiopulmonary bypass time. The model demonstrated robust performance, with area under the curve values of 0.749 and 0.753 in internal and external validation cohorts, respectively. Decision curve analysis confirmed the nomogram's clinical utility, providing superior net benefit over postoperative creatinine levels when the predicted AKI risk exceeds 50%. This tool enables early identi
