摘要

Abstract Objective To evaluate the risk factors of postoperative hypoxemia in patients after triple‐branched stent graft implantation surgery with acute type A aortic dissection by conducting a nomogram. Methods We evaluated 97 patients with acute type A aortic dissection (2020–2021), who?underwent triple‐branched stent graft implantation surgery. The independent risk factors were screened using univariate and multivariate logistic regression. We integrated significant factors as well as potential interference factors to build the nomogram model. The accuracy of the nomogram model was determined by using receiver operating characteristic curves (ROC), decision curve analyses (DCA), and calibration plots. Internal verification was evaluated using bootstrap validation. Results Logistic regression analysis illustrated that the postoperative lactic acid, postoperative creatinine, and intraoperative aortic occlusion time were all independent risk factors for hypoxemia. Age, sex, and body mass index (BMI) were clinically relevant for predicting postoperative hypoxemia. We established a nomogram based on these six risk factors. The ROC?(area?under the curve?AUC?=?0.765), DCA, and calibration confirmed good discriminatory applicability and accuracy of the nomogram. Bootstrap validation (AUC?=?0.76) verified the applicability of the nomogram. Conclusions The nomogram model could serve as a tool for the prediction of postoperative hypoxemia in patients after modified triple‐branched stent graft implantation surgery with acute type A aortic dissection.
