Summary of "Effect of massive blood transfusion on late outcomes after surgical repair of acute type A aortic dissection."

Massive blood transfusion (MBT) increased mortality and morbidity after cardiac surgery. However, a mid-term follow-up study on repair surgery of acute type A aortic dissection (AAAD) with MBT was lacking. This study aimed to assess the impact of perioperative MBT on late outcomes of surgical repair for AAAD.There were 3209 adult patients firstly received repair surgery for AAAD between 2005 and 2013, were identified using Taiwan National Health Insurance Research Database. Primary interest variable was MBT, defined as transfused red blood cell (RBC) ≥10 units.The outcomes contained in-hospital mortality, surgical-related complications, all-cause mortality, respiratory failure, and chronic kidney disease (CKD) during follow-up period. Higher in-hospital mortality (37.7% vs 11.6%; odds ratio, 4.00; 95% confidence interval [CI], 3.30-4.85), all-cause mortality (26.1% vs 13.0%; hazard ratio [HR], 1.66; 95% CI, 1.36-2.04), and perioperative complications were noted in the MBT group. A subdistribution hazard model revealed higher cumulative incidence of CKD (13.9% vs 6.5%; HR, 1.95; 95% CI, 1.47-2.60) and respiratory failure (7.1% vs 2.7%; HR, 2.34; 95% CI, 1.52-3.61) for the MBT cohort. A dose-dependent relationship between amount of transfused RBC (classified as tertiles) and cumulative incidence of all-cause mortality, incident CKD, and respiratory failure was found (P of trend test <.001).Patients with MBT had worse late outcomes following surgical repair of AAAD. The cumulative incidence of all-cause mortality, incident CKD, and respiratory failure increased with the amount of transfused RBC in a dose-dependent manner.
