Value of Thromboelastography as a Predictor of Postoperative Acute Respiratory Distress Syndrome in Patients With Acute Type A Aortic Dissection

Background: This study aimed to evaluate the effectiveness of thromboelastography (TEG) in predicting postoperative acute respiratory distress syndrome (ARDS) in patients with acute type A aortic dissection (ATAAD). Methods: This retrospective cohort study included 350 consecutive patients with ATAAD who underwent emergency total aortic arch replacement surgery at our institution. Patients were divided into ARDS and non-ARDS groups based on the postoperative development of ARDS. Perioperative data were collected and compared between groups. Results: < 0.001). Conclusion: Preoperative fibrinogen, clot angle, and MA may be useful predictors of postoperative ARDS in patients with ATAAD. TEG enables rapid preoperative assessment of coagulation system status, guiding fibrinogen supplementation and blood transfusion strategies to reduce the incidence of postoperative ARDS and shorten the duration of postoperative mechanical ventilation. Thus, TEG may be a valuable tool for real-time monitoring and improving postoperative outcomes in this population.
