大鼠原位肝肾联合移植模型的建立

目的建立一种简易可靠的大鼠肝肾联合移植模型。方法SD大鼠作同品系异体移植的供受体。整块切取供鼠肝脏及肾脏,肝下下腔静脉在右肾静脉以下切断,肾动脉在根部切断;切除受体肝及右肾;供肝肝上下腔静脉用显微外科技术缝合,双袖套法吻合肾下下腔静脉及门静脉,右肾动脉采用显微外科技术与受体肾动脉吻合;用支架管重建胆道和输尿管。结果移植血管吻合时间短,受体手术时间短,手术成功率为73.3%,移植肝及肾功能良好。结论此模型是一种较为简易、可靠的大鼠肝肾联合移植模型。

Establishment of rat models of simultaneous liver and kidney transplantation

Objective To establish a simple and reliable rat model of simultaneous liver and kidney transplantation. Methods The simultaneous transplantation was performed in healthy male SD rats as the recipients and other SD rats of either gender as the donors. The donor liver and kidney were resected simultaneously and grafted into the recipients whose corresponding organs were previously removed. Anastomosis of the portal vein and the inferior vein cava (IVC) inferior to the kidney between the graft and the recipient was performed by a double cuff method, followed by end-to-side anastomosis of the IVC superior to the liver between the donor and the recipient. The urethra and bile duct were anastomised using a simple inside bracket. Results The time for blood vessel anastomosis and for recipient operation were reduced, with a success rate of 73.3% in the operations. The function of the grafted liver and kidney remained normal. Conclusion This rat model of simultaneous liver-kidney transplantation is simple and reliable.
