Outcomes were postoperative clinical outcomes, early and follow-up survival.Results: A total of 517 complicated TBAD patients were enrolled. POD was observed in 13.3% (69/517) patients and was associated with increased hospital length of stay (LOS) and hospital costs (P 2 mg/dL (OR 3.25, 95% CI 1.57– 6.72, P= 0.001) and preoperative blood transfusion (OR 3.31, 95% CI 1.76– 6.21, P 2 mg/dL and preoperative blood transfusion, were identified as independent risk factors for POD. Effective risk-stratification and patient-tailored management strategy should be developed to reduce the incidence of POD.Keywords: type B aortic dissection, thoracic endovascular aortic repair, hybrid procedure, postoperative delirium, predictors, outcomes
