Objective To identify the predictors of postoperative acute kidney injury in patients undergoing surgery for Stanford type A acute aortic dissection. Methods A total of 220 patients who underwent surgery for type A acute aortic dissection in Qingdao Municipal Hospital from September 2010 to September 2017 were divided into two groups including a group A and a group B based on whether acute kidney injury occurred or not after surgery. There were 40 patients with 29 males and 11 females with the mean age of 54.6±9.2 years in the group A, 180 patients with 133 males and 47 females with the mean age of 48.5±7.9 years in the group B. Univariate and multivariate analyses (logistic regression) were used to identify the predictive risk factors. Results Overall in-hospital mortality was 5.5%. In univariate analysis, there were statistically significant differences with respect to the age, preoperative creatinine, preoperative white blood cell, the European system for cardiac operative risk evaluation (EuroSCORE), total cardiopulmonary bypass (CPB) time, deep hypothermic circulatory arrest (DHCA) time, arch replacement, red blood cell transfusion intraoperative and in 24 hours postoperatively, postoperative mechanical ventilation time, ICU stay duration, hospital stay duration and in hospital mortality. Multivariate logistic analysis showed that preoperative creatinine, preoperative white blood cell, CPB time, and red blood cell transfusion intraoperative and in 24 hours postoperatively were the independent predictors for postoperative acute kidney injury. Conclusion The incidence of acute kidney injury is high after surgery for acute Stanford type A aortic dissection. It can be predicted based on above factors, for patients with these risk factors, more perioperative care strategies are needed in order to induce the incidence of acute kidney injury.

Objective To investigate the feasibility and safety of hybrid coronary revascularization (HCR) in patients with multivessel coronary artery disease (MVCAD). Methods A total of 50 patients with MVCAD who underwent HCR technique in our heart center from May 2016 to April 2019 were included in this study (a HCR group), including 38 patients who underwent two-stage HCR and 12 patients one-stop HCR. There were 39 males and 11 females, with an average age of 62.4 (46-82) years. Another 482 patients who underwent conventional median incision under off-pump coronary artery bypass grafting (OPCAB) at the same period were selected as control (an OPCAB group), including 392 males and 90 females, with an average age of 64.2 (48-84) years. The safety and feasibility of HCR were evaluated and compared with conventional OPCAB technique. Results There was no perioperative death in both groups. Compared with the OPCAB, HCR was associated with shorter operation time, less chest tube drainage, lower requirement of blood transfusion, shorter mechanical ventilation time and shorter postoperative intensive care unit (ICU) stay (P<0.05). There was no statistical difference in the incidence of major adverse cardiac or cerebrovascular events during the follow-up of 6 to 36 months between the two groups. Conclusion HCR provides favorable short and mid-term outcomes for selected patients with MVCAD compared with conventional OPCAB.
