  1. AKI acute kidney injury, ADTIAD acute DeBakey Type I aortic dissection, AMI acute myocardial infarction, BMI body mass index, BUN blood urea nitrogen, CPB cardiopulmonary bypass, FET frozen elephant trunk, PRBCs packed red blood cells, sCr serum creatinine, TAR total arch replacement, OR Odd Ratio, 95% CI 95% confidence interval
  2. Model I: adjust for none
  3. Model II: adjust for age; gender
  4. Model III: adjust for age; gender; BMI; smoking history; aortic cross clamp time; nasopharyngeal temperature at circulatory arrest; combined with aortic bypass surgery; AMI; Intraoperative transfusion of PRBCs
  5. Model IV: adjust for age; gender; BMI; smoking history; aortic cross clamp time; nasopharyngeal temperature at circulatory arrest; combined with aortic bypass surgery; AMI; Intraoperative transfusion of PRBCs; renal artery dissection or occlusion; Penn class; kidney malperfusion; preoperative shock; Bentall+TAR+FET
