Data presented as median (25%, 75%) for continuous data and n (%) for categorical data. P value indicates the difference between men and women. MI, Myocardial infarction; LOS, length of stay.
New-onset acute renal failure = new-onset acute renal failure or worsening renal function after ATAAD repair resulting in (1) an increase in serum creatinine level 3 times greater than baseline or serum creatinine level 4 mg/dL or greater, and the acute increase must be at least 0.5 mg/dL or (2) a new requirement for dialysis postoperatively.
In-hospital mortality = death within hospitalization during which the operation occurred.
Thirty-day mortality = death within 30 d of the operation.
Operative mortality includes 30-d mortality or in-hospital mortality.
