改良"二袖套法"制备大鼠原位肝移植动物模型

目的：建立稳定的大鼠原位肝移植模型。方法：在Kamada等用袖套法吻合血管的基础上,采取肝上、下腔静脉缝合的二袖套方法,根据不同实验目的在3个月中行大鼠原位肝移植共62只。结果：切取供肝时间平均32min,修肝时间平均12min,无肝期平均18min。手术成功率提高到90％。结论：应用二袖套法制作的实验模型稳定,可作为肝移植实验研究的有效手段。

A modified animal model of orthotopic liver transplantation in rat

Objective:To make an ideal model for liver transplantation. Methods:On the basis of cuff technique,we carried out 62 cases of orthotopic liver transplantation in 3 months. In the transplantation,we anastomosed the portal vein and subhepatic vena cava with cuff and conneted the suprahepatic vena cava to the recipient's diaphragm with 9-0 running suture. Results:The average time of acquiring donor liver was 32 minutes, reqairing liver was 12 minutes,unhepatic phase was 18 minutes.62 liver transplantation operations were carried out ,in which the operation success rate in late 30 cases was 90%. Conclusion:The results show that the model is stable and can be used in the experiment of liver transplantation.
