目的 总结无冠窦补片在Standford A型夹层根部成形手术中应用效果。方法 采用回顾性研究方法，选择2008 年 3-5 月 86 例 Standford A型主动脉夹层患者（A组）和2018 年 6 月至 2020 年 10 月 66 例 Standford A 型夹层患者（B组）在我院行“孙氏手术”手术，A组手术中在主动脉根部行主动脉壁与右心耳做内引流，B组手术中主动脉根部采用无冠窦补片，主动脉根部血管壁采用“三明治”缝合加固的方法，右无瓣膜交界行悬吊成形。分析两组间手术时间、术中出血量、体外循环时间、术中输注红细胞量、术后再次开胸手术止血例数、术后24 h 总引流量、术后输红细胞量、术后发生肺部并发症例数、术后病死率。结果 B 组患者在手术时间、体外循环时间、术中输注红细胞量、术后再次开胸手术止血例数、术后24 h 总引流量、术后输红细胞量、术后发生肺部并发症例数、术后病死率等方面均明显低于A组。结论 Standford A型主动脉夹层手术中，主动脉根部采用无冠窦补片，主动脉根部血管壁采用“三明治”缝合加固的方法，可减少术后并发症，提高手术成功率。

Objective To explore the effect of crownless sinus patch in Standford type A dissection root plasty. Methods A total of 86 cases of Stanford type A aortic dissection from March 2008 to May 2018 were selected as Group A and another 66 cases with the same conditions from June 2018 to October 2020 were selected as group B. The patients of the two groups underwent Sun′s operation in our hospital. During the operation，the aortic wall and right atrial appendage were used for internal drainage at the aortic root in group A. In group B，the aortic root was repaired with non⁃coronary sinus patch，the vascular wall of aortic root was sutured with“Sandwich” method and the right valueless junction was suspended and shaped. The two groups were compared in terms of operation time，intraoperative blood loss，cardiopulmonary bypass time，intraoperative red blood cell transfusion， number of homeostasis cases after thoracotomy，total drainage volume 24 hours after operation，number of postopera⁃ tive pulmonary complications and mortality rate. The data were analyzed by SPSS10.0. Group t test and χ2 test were used for statistical analysis of measurement data and count data between groups. Results As compared with group A，the operation time and cardiopulmonary bypass time were both significantly shorter，the volume of transfused intraoperative red blood cells，the number of homeostasis cases after thoracotomy，the total drainage volume in 24 hours after operation，the amount of red blood cell transfusion，and the number of cases with pulmonary complications were significantly smaller，and the postoperative mortality was significantly lower in group B. Conclusion During Stanford type A aortic dissection，aortic root plasty with non ⁃coronary sinus patch，with its vascular wall sutured and reinforced with“Sandwich”method，is effective in reducing postoperative complications and improve the success rate of operation.
