【摘要】 目的为了简化手术步骤,方便操作,提高手术成功率。方法采用wistar大鼠(200～250g)为供体,SD大鼠(200～250g)为受体,行同种带瓣主动脉腹主动脉补片式异位移植36例。供体经修剪保留两个主动脉瓣叶及相应宽度瓣下附着心肌(0.5mm)和主动脉壁(5mm),三定点连续缝合法移植于左肾静脉下方腹主动脉前壁。结果手术成功率为94.4%。结论实验结果提示:与腹主动脉间置式移植相比,本手法操作简单,成功率高,可满足类似实验要求。更多还原

Results The operative survival rate was 94.4%. Conclusion It was suggested that compared with the implantation of interposing graft into abdominal aortic position by an end-to-end anastomosis, this method has higher operative survival rate, and make the operation more convenient. It can meet the same experimental requirment.更多还原
