Conclusion
This study identified the following as risk factors for severe ALI after ATAAD: CHD, CPB duration ≥ 257.5 min, LA diameter ≥ 35.5 mm, hemoglobin ≤ 139.5, ICU OI ≤ 100 mmHg, LVPWT ≥ 10.5 mm, NEUT ≥ 0.824, and preCPB OI ≤ 100 mmHg. The identified factors were included in a prediction model, and a nomogram was drawn to facilitate risk assessment. The variables identified are easy to obtain in clinical settings and will allow clinicians to predict the occurrence of severe ALI after ATAAD more rapidly and effectively.
