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< 0.001 for both). Besides, POD was found to be an independent risk factor for prolonged ICU stay (odds ratio [OR] 4.39, 95% confidence interval [CI] 2.40– 8.01, P< 0.001) and early death (OR 4.42, 95% CI 1.26– 15.54, P= 0.020). Predictors of POD were hybrid procedure (OR 2.17, 95% CI 1.20– 3.92, P= 0.010), the use of benzodiazepine (OR 1.86, 95% CI 1.07– 3.23, P= 0.027) or quinolone (OR 2.35, 95% CI 1.26– 4.38, P= 0.007), creatinine > 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< 0.001). After a median follow-up of 73.6 months, POD remained as an independent indicator for follow-up mortality (hazard ratio [HR] 2.40, 95% CI 1.31– 4.38, P= 0.005) after adjusting potential confounders.Conclusion: POD after TEVAR has an incidence of around 13% and could profoundly increase the in-hospital LOS, hospital costs, as well as the early and follow-up mortality. A series of risk factors, including hybrid procedure, the use of benzodiazepine or quinolone, creatinine > 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
