Objective: This study was conducted to evaluate pre- and intraoperative risk factors for 30-day mortality in patients with acute type A aortic dissection (ATAAD). Methods: Three hundred thirteen patients with ATAAD who underwent emergency surgery (264 men and 49 women; mean age, 48±10 years) were enrolled in our study. Preoperative and operative risk factors for death were presented. Multivariable analysis was performed to identify the influence of varying factors on 30-day mortality. Results: Overall, 32 patients (10.2%) died within 30 days. Compared with the surviving group, the deceased patients were more likely to have tachycardia, elevated serum potassium levels, moderate to severe pericardial effusion, suprasternal branch involvement, myocardial ischemia, and lower-extremity ischemia. Regarding factors related to surgery, the duration of surgery and cardiopulmonary bypass and concomitant procedures of coronary artery bypass graft（CABG） were greater in patients who died. In multivariate analysis, independent risk factors were longer duration of surgery (odds ratio [OR]: 4.5, p=0.001) and cardiopulmonary bypass (OR: 5.3, p=0.001), moderate to severe pericardial effusion (OR: 3.3, p=0.017), suprasternal branch involvement (OR: 4.9，p=0.002), and lower-extremity ischemia (OR: 7.6, p＜0.001). Conclusions: Lower-extremity ischemia and suprasternal branch involvement have the poorest outcomes. Moderate to severe pericardial effusion could influence the outcome. Shorter duration of surgery is associated with better outcomes. Key Words: acute type A aortic dissection, surgery, mortality, risk factors

Background: Mortality in acute Type A aortic dissection is still high and unpredictable. We aimed to investigate the validity of preoperative hematological markers and possible risk factors in predicting in-hospital mortality in patients operated with deep hypothermic circulatory arrest method. Methods: 78 consecutive patients who were admitted to the emergency service and operated on were retrospectively analyzed. Risk factors for in-hospital death were investigated to develop a predictive model. Results: There was no difference between patients in terms of the were demographic data of the patients. In the mortality group, only preoperative creatinine levels were found to be higher (p < 0.05). Factors affecting mortality were found as total circulatory arrest (TCA) and cross-clamp (X-clamp) times when intraoperative data were examined (p < 0.05). ROC analysis was performed to determine the power to predict mortality and to determine the cut-off point. In ROC analysis to predict mortality, X-Clamp time > 71 minutes, 68.2% sensitivity and 66.1% specificity, TCA > 44.5 minutes, 72.7% sensitivity and 73.2% specificity were found. In the mortality group, these values were found to be significantly higher than those who were discharged. Conclusion: In the surgical treatment of Type A aortic dissection under deep hypothermia, hematologic biomarkers may be insufficient in estimating the risk for mortality.

Hemiarch Replacement

Background Aortic enlargement after hemiarch replacement (HAR) for acute type A aortic dissection (AAAD) is a serious problem. We reviewed our experience and analyzed the risk factors for aortic enlargement. Methods During April 2005 to December 2017, 364 patients underwent HAR for AAAD. Seventy-three patients fulfilled the inclusion criteria. We analyzed the change in aortic diameter, aortic growth rate, and major adverse aortic events (MAAEs) and their association with luminal communication of the aortic arch. Results Anastomotic communication, supra-aortic communication (SAC), and distal aortic communication were found in 34 (46.6%), 28 (38.4%), and 20 (27.4%) patients, respectively. The aortic growth rate was high because of the presence of SAC, distal aortic communication, and the number of coexisting aortic communication. Univariate analysis showed that the presence of SAC and an initial aortic diameter > 35 mm at 20 mm distal to the left subclavian artery and at the pulmonary artery bifurcation (PAB) were risk factors for MAAEs. Multivariate analysis showed that SAC and an initial aortic diameter > 35 mm at the PAB were independent risk factors for MAAEs. Conclusion SAC, distal aortic communication, and the number of coexisting aortic communication are significant risk factors for aortic enlargement after HAR for AAAD. SAC and an initial aortic diameter > 35 mm at the PAB are independent risk factors for MAAEs after this procedure.
