【摘要】 目的探讨孙氏术式在老年急性Stanford A型主动脉夹层的应用价值。方法选取北京安贞医院2018年9月至2019年9月连续采用全麻、深低温停循环（DHCA）加单侧选择性脑灌注技术行孙氏术式治疗的44例急性Stanford A型主动脉夹层患者作为研究对象。患者年龄≥60岁为老年组（n=9),<60岁为年轻组（n=35）。比较两组术中、术后情况及不良事件发生情况。结果两组患者在发病至手术时间、体外循环时间、主动脉阻断时间、DHCA时间比较差异无统计学意义（P>0.05），老年组患者较年轻组患者住ICU时间、总住院时间显著延长（P<0.05）。两组患者术后不良事件发生情况比较差异无统计学意义（P>0.05）。结论老年急性Stanford A型主动脉夹层患者接受孙氏术式后不良事件发生风险与年轻患者类似，但住ICU时间和总住院时间更长。更多还原

【Abstract】 Objective To explore the application value of Sun′s Procedure in elderly patients with acute Stanford type A aortic dissection.Methods Forty-four patients with acute Stanford type A aortic dissection who received continuous general anesthesia,deep hypothermic circulatory arrest(DHCA) and unilateral selective cerebral perfusion technique and were treated with Sun′s Procedure in Beijing Anzhen Hospital from September 2018 to September 2019were selected as the study subjects.The patients with age≥60 years were selected as the elderly group(n=9),and those with age<60 years as the young group(n=35).The intraoperative and postoperative situations and the occurrence of adverse events were compared between the two groups.Results There was no significant difference between the two groups in the time from onset to operation,the time of cardiopulmonary bypass,the time of aortic occlusion and the DHCA time(P>0.05).The intensive care unit(ICU) stay and the total hospital stay in the elderly group were significantly longer than those in the young group(P<0.05).There were no significant differences in the postoperative adverse events between the two groups(P>0.05).Conclusion The risk of adverse events in elderly patients with acute Stanford A aortic dissection after receiving Sun′s Procedure is similar to that in young patients,but the elderly patients have longer ICU stay and total hospital stay.更多还原
