    Abstract

    Background. This study was undertaken to identify preoperative and postoperative predictors of hospital death of patients with acute type A aortic dissection. Methods. Between May 1,1992, and July 31, 2004, 106 consecutive patients (59 male and 47 female, mean age 62.2 ± 12.1 years) with acute type A aortic dissection underwent surgery with open technique and cerebral protection by antegrade selective cerebral perfusion. The external iliac artery or femoral artery alone was used for arterial cannulation in 37 patients; however, the right axillary artery was cannulated in 69 patients. Univariate analysis of potential risk factors was performed to identify risk factors for hospital death and was followed by multivariate analysis by a stepwise logistic regression model to identify independent risk factors. Results. Sixteen patients died postoperatively, and the overall hospital mortality rate was 15.1%. Univariate analysis revealed shock (p = 0.020), visceral ischemia (p = 0.007), root replacement (p = 0.041), and absence of axillary artery perfusion (p = 0.003) as significant risk factors for hospital death. Multivariate analysis revealed visceral ischemia (p = 0.0028, odds ratio 18.4) and absence of axillary artery perfusion (p = 0.0014, odds ratio 8.2) as independent preoperative and intraoperative predictors of hospital death. Conclusions. Achievement of greater success in the surgical treatment of acute type A dissection will require axillary artery cannulation and measures to prevent visceral malperfusion.
