Predictors of Prolonged Mechanical Ventilation in Adults After Acute Type-A Aortic Dissection Repair

In this study, the occurrence of PMV was 28.9% in patients with ATAAD. A lower preoperative platelet count and a higher serum lactate level after ATAAD surgery were risk factors for PMV. Identification of risk factors may be helpful for preventing PMV and improving outcomes after surgical repair of ATAAD.
