2、时间约30min(不含热缺血时间)。供肝冷保存时间均为1h。肝上下腔静脉吻合时间l2~22min(平均15min),门静脉和肝下下腔静脉套管分别约需2min和1min。无肝期时间14~24min(平均19min),受体总手术时间5o~65min(平均60min)。大鼠术后24h内死亡视为手术失败,共计12例死亡。R10组、R20组和R3o组手术成功率分别为95%(19/20)、80%(16/20)和65%(13/20),术后1周生存率分别为95%(18/19)、81%(13/16)和54%(7/13)。结论在Kamada“二袖套法”基础上进行改良的大鼠无心跳供
3、肝肝移植模型能很好地模拟临床无心跳供肝肝移植。大鼠肝脏能耐受30min以内的热缺血时间,移植术后短期存活结果满意,长期存活率尚需进一步研究。【关键词】无心跳供肝;肝移植;大鼠;动物模型【中图分类号】R657.3【文献标识码】ASurgicalSkillsofNon-Heart-BeatLiverinRatLiverTransplantati0nModelLIJing—feng,DINGHuan—xin,BAIJian—hua,LIXiao—yah,GUANAo—ran.*LiverTrn72户以f0,zDivision,TheFirstPeople’sHosp
