目的为树鼩肝移植的开展提供解剖学基础。方法解剖12只成年树鼩观察肝脏形态、毗邻及主要血管、胆管的走形和分布,并在解剖基础上探讨和对3组树鼩采用“双袖套管法”行肝移植术。结果树鼩肝动脉直径(0.63±0.21)mm,均发自腹腔干;肝上下腔静脉距横膈(5.35±0.55)mm,直径(6.86±0.61)mm;肝下下腔静脉直径(5.28±0.58)mm;肝门静脉由肠系膜上静脉及脾静脉汇成,直径(3.86±0.57)mm;胆总管由胆囊管及肝总管汇成,长度(15.5±2.6)mm;直径(0.75±0.12)mm。3组树鼩顺利行肝移植术操作,术后存活时间为3h、5h和6h。结论树鼩在解剖学基础上建立肝移植模型具有一定的可行性。
Objective To provide anatomical basis for the development of tree 鼩 liver transplantation. Methods Twelve adult tree shrews were dissected to observe the shape and the adjacent liver pathways and the distribution of the main blood vessels and bile ducts. The anatomical basis was discussed and the “double sleeve method” liver transplantation was performed on the three tree shrews. Results The diameter of the hepatic artery in the tree 鼩 was (0.63 ± 0.21) mm, both of which originated from the celiac trunk. The diameter of the superior and inferior hepatic vein was (5.35 ± 0.55) mm, and the diameter of the inferior hepatic inferior vena cava was 5.28 ± 0.58) mm. The hepatic portal vein was merged into the superior mesenteric vein and splenic vein with a diameter of (3.86 ± 0.57) mm. The common bile duct was formed by the cystic duct and the common hepatic duct, with a length of (15.5 ± 2.6) mm and a diameter of (0.75 ± 0.12) mm . Three groups of tree 鼩 successful liver transplantation operation, postoperative survival time was 3h, 5h and 6h. Conclusion It is feasible to establish a liver transplantation model based on anatomy.
