目的:探讨自制人工血管预缝合心包片行右心房内引流技术在Stanford A型主动脉夹层中的疗效。方法:回顾性分析2016年12月至2019年10月中国科学技术大学附属第一医院60例行孙氏手术的Stanford A型主动脉夹层患者的临床资料。其中，采用直接包裹人工血管行内引流26例（A组），采用自制人工血管预缝合心包片行内引流34例（B组）。比较两组术中和术后情况。结果:手术均顺利完成。B组体外循环时间、术中红细胞用量、术中血浆用量和术后24 h引流量明显少于A组［（174.09 ± 12.11） min比（225.23 ± 20.40） min、（5.56 ± 1.16） U比（10.50 ± 2.25） U、（650.00 ± 137.62） ml比（953.85 ± 221.33） ml和（515.59 ± 89.16） ml比（667.88 ± 76.55） ml］，差异有统计学意义（n P0.05）。n 结论:Stanford A型主动脉夹层患者采用自制人工血管预缝合心包片行孙氏手术的方法使手术操作简化，进一步优化了内引流技术，利于减少术中出血量和用血量，缩短体外循环时间，效果确切。“,”Objective:To explore the efficacy of right atrium drainage method in Stanford A aortic dissection by using self made artificial blood vessel pre-sewed and wrapped the pericardium.Methods:The clinical data of 60 Stanford type A aortic dissection patients undergoing Sun′s surgery in the First Affiliated Hospital of University of Science and Technology of China from December 2016 to October 2019 were retrospectively analyzed. Among them, 26 patients were treated with directly wrapped artificial blood vessels for right atrial drainage (group A), and 34 patients were treated with self made artificial blood vessel pre-sewed and wrapped the pericardium (group B). The intraoperative and postoperative conditions were compared between 2 groups.Results:All operations were completed successfully. The extracorporeal circulation time, intraoperative red blood cell dosage, intraoperative plasma dosage and 24 h postoperative drainage volume in group B were significantly lower than those in group A: (174.09 ± 12.11) min vs. (225.23 ± 20.40) min, (5.56 ± 1.16) U vs. (10.50 ± 2.25) U, (650.00 ± 137.62) ml vs. (953.85 ± 221.33) ml and (515.59 ± 89.16) ml vs. (667.88 ± 76.55) ml, and there were statistical differences (n P0.05).n Conclusions:Self made artificial blood vessel pre-sewed and wrapped the pericardium is used to perform Sun′s operation in Stanford type A aortic dissection patients, which simplifies the operation and further optimizes the internal drainage technology and is beneficial to reduce the intraoperative blood loss and blood consumption and reduce the extracorporeal circulation time, and the effect is accurate.
