The retrospectively presented by Xu et al. assessed the value of the systemic immune‐inflammation index (SII) in the prediction of short‐term outcomes in patients undergoing surgery for acute type A aortic dissection (ATAAD). The authors concluded that SII is a reliable biomarker that can predict postoperative short‐term outcomes and this marker could be potentially applied to stratification and patient selection with ATAAD. Although the study is retrospective, it is well‐matched and conducted in a large volume center and the surgical technique was standard for all procedures. In addition, there was no statistical difference in cardiopulmonary bypass, aortic cross‐clamp and deep hypothermic time, comorbidities, blood and blood products transfusion between the study groups. In addition, 90.7% of patients underwent elephant trunk technique for ATAAD repair, while the 30‐day mortality and postoperative temporary and permanent neurological dysfunctions were 14.8% and 11.1%, respectively. Randomized controlled and prospective studies are warranted to clarify these well‐documented results to apply this useful biomarker in clinical practice for patients with the acute aortic syndrome.
