Sumario:BACKGROUND: Hepatic dysfunction (HD) is a common complication that can occur after surgical repair of acute type A aortic dissection (ATAAD) and is associated with poor prognosis. However, the incidence of early preoperative HD and the associated risk factors in patients with ATAAD have not been fully elucidated. METHODS: A total of 984 ATAAD patients who received surgical repair within 48 hours of symptom onset at our department from January 2014 to December 2019 were retrospectively analyzed. Patients were divided into the non-HD group and the HD groups according to the Model of End-Stage Liver Disease (MELD) score before surgery. The clinical parameters and clinical outcomes of the 2 groups were collected and compared. RESULTS: Preoperative HD was detected in 268 patients (27.2%). The incidence of in-hospital complications, including the need for dialysis (34.0% vs. 9.2%; P<0.001), was significantly higher in patients with HD compared to patients without HD (69.8% vs. 51.0%; P<0.001). Patients with HD had a higher 30-day mortality rate compared to patients without HD (20.1% vs. 8.4%; P<0.001). Multivariate analysis demonstrated that preoperative cardiac tamponade, preoperative serum creatinine levels, and serum troponin T levels upon admission were independent predictors for preoperative HD in patients with ATAAD. Interestingly, even though preoperative HD was associated with an increased 30-day mortality rate, it did not significantly affect the long-term mortality rate (log-rank P=0.259). CONCLUSIONS: Early HD before surgery was commonly observed in patients with ATAAD and was associated with increased in-hospital complications after surgery, but did not significantly affect long-term survival.
