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.

A 50-year-old black male presented with acute type A aortic dissection. Surgical repair was performed under deep hypothermic circulatory arrest (DHCA) with lung perfusion/ventilation throughout the procedure. Details of the lung perfusion technique and its potential benefits and drawbacks are discussed.

Background: The hypothermic circulatory arrest (HCA) is an indispensable step in the surgical treatment of an acute type A aortic dissection (ATAAD), which could greatly affect the postoperative outcome. We modified the HCA technique and validated the feasibility and superiority of the new approach relative to the conventional method. Methods and results: Eighty-eight patients with ATAAD were enrolled in this study between May 2016 and April 2018. Of those, 36 patients in the Conventional treatment group had circulatory arrest at 25°C for about 16-28 minutes, while 52 patients in the Modification group underwent a circulatory arrest at 28°C for only 1-3 minutes. The preoperative clinical data and postoperative clinical outcomes were compared between the two groups. No intraoperative mortality occurred in any of the cases. No significant differences were observed in the aortic cross-clamp times during the cardiopulmonary bypass (CPB) between the two groups. In the Modification group, several indicators, such as mechanical ventilation time, postoperative 48-h drainage volume, blood transfusion volume, the ICU-stay time and postoperative hospital stay, were reduced significantly as compared with those in the Conventional group. Whereas three postoperative deaths in the hospital occurred in the Conventional treatment group, all the patients in the Modification group were cured. There is no difference in the incidence of postoperative complications between the two groups. The patients had a 100% follow up with a mean of 17 ± 6 months. Conclusions: A moderate hypothermia with a short circulatory arrest is a safe and effective HCA approach that provides satisfactory early and near-midterm results in the patients who received ATAAD treatment.

Abstract Background Sun’s procedure is currently recognized as the standard procedure for acute type A aortic dissection (AAAD). But the operation istoo difficult for beginners. We hope to reduce the difficulty and complications of this operation. Methods The aortic arch was immediately cross-clamped after the stented graft was inserted into the distal aorta. Thereafter, the lower-body perfusion was restored. Then, anastomosis was performed between the proximal stent graft and the distal 4-branched Dacron graft. The other arteries were anastomosed to the arched branch of the 4-branched graft. Results The cardiopulmonary bypass (CPB) time was (207 ± 52) min, and the aortic cross-clamp time was (114 ± 39) min. The circulatory arrest time was (38 ± 16) sec. One patient (4%) died. The incidence of complications was stroke (4%), renal dysfunction requiring dialysis (4%), prolonged intubation(12%). Conclusions The time of circulatory arrest in this operation is less than 1 min, which can avoid the complications caused by DHCA and decrease risk of bleeding and complexity by shifting anastomosis more proximally. The effect of our operation is similar to and even better than that of Sun’s procedure. It does not even require relatively advanced skill, much experience and excellent psychological quality, especially suitable for beginners.

Background: The treatment of complex thoracic aorta pathologies remains a challenge for cardiovascular surgeons. After introducing Frozen Elephant Trunk (FET), a significant evolution of surgical techniques has been achieved. The present meta-analysis aimed to assess the efficacy of FET in acute type A aortic dissection (ATAAD) and the effect of circulatory arrest time on post-operative neurologic outcomes. Methods: A standard Preferred Reporting Items for Systematic Reviews and Meta-Analyses search was conducted for all observational studies of patients diagnosed with ATAAD undergoing total arch replacement with FET reporting in-hospital mortality, bleeding, and neurological outcomes. A random-effect meta-analysis was performed using STATA software (StataCorp, TX, USA). Results: Thirty-five studies were eligible for the present meta-analysis, including 3211 patients with ATAAD who underwent total arch replacement with FET. The pooled estimate for in-hospital mortality, postoperative stroke, and spinal cord injury were 7% (95% CI 5 – 9; I2 = 68.65%), 5% (95% CI 4 – 7; I2 = 63.93%), and 3% (95% CI 2 – 4; I2 = 19.56%), respectively. Univariate meta-regression revealed that with increasing the duration of hypothermic circulatory arrest time, the effect sizes for postoperative stroke and SCI enhances. Conclusions: It seems that employing the FET procedure for acute type A dissection is associated with acceptable neurologic outcomes and a similar mortality rate comparing with other aorta pathologies. Besides, increasing hypothermic circulation arrest time appears to be a significant predictor of adverse neurologic outcomes after FET.
