Abstract:
The aim of this study was to evaluate independent risk factors predictive for mortality of patients with Stanford A acute aortic dissection. Methods: From January 2006 to March 2015, a total of 240 consecutive patients diagnosed with acute Stanford A acute aortic dissection underwent surgical aortic repair in our center. After analysis of pre- and perioperative variables, univariate logistic and multivariate logistic regression analyses were performed for mortality of patients. Subsequently, Kaplan–Meier estimation analysis of short- and long-term survival of these variables was carried out. Results: Primary entry tear in descending aorta (odds ratio = 4.71, p = 0.021), preoperative international normalized ratio higher than 1.2 (odds ratio = 7.36, p = 0.001), additional coronary artery bypass grafting (odds ratio = 3.39, p = 0.003), cannulation in ascending aorta (odds ratio = 3.22, p = 0.005), preoperative neurological coma (odds ratio = 3.30, p = 0.003), and reduced perfusion (odds ratio = 2.91, p = 0.006) as well as prolonged reperfusion time (odds ratio = 3.36, p = 0.002) showed to be independent predictors for early mortality as well as for late mortality (hazard ratio of all variables p 〈 0.05). Kaplan–Meier survival estimation analysis with up to 9-year-follow-up in terms of these risk factors showed significantly poorer short- and long-term survival (log-rank and Breslow test all p 〈 0.05). Conclusion: Our study revealed that early and late mortality of patients with Stanford A acute aortic dissection surgery was significantly influenced by preoperative and perioperative variables as independent predictors especially of variables displaying coronary, cerebral, and visceral malperfusion. Also, short- and long-term survival of patients was significantly poorer in terms of these risk factors.
