  1. The predictive model was adjusted by pH, lactate, bicarbonate, decreased peripheral arterial pulse, hypertension, coronary artery disease, stroke, anemia, estimated glomerular filtration rate < 60 mL/min/1.73 m2, extent of the dissection, blood supply of visceral arteries (coeliac artery, superior mesenteric artery, left renal artery and right renal artery)
  2. OR, odds ratio; CI, confidence interval
  3. *Base excess was divided into low risk group (> − 5), moderate risk group (− 10 to − 5) and high risk group (≤ − 10)
