人肝脏劈离的解剖实验研究

目的 比较劈离式肝移植两种主要劈离方式，即经典劈离方式和改良劈离方式的差异。以选择一种安全易行的技术。方法 将58个甲醛固定的成人尸肝和8个新鲜肝脏分别采用经典劈离方式和改良劈离方式进行分离。比较肝脏各段动脉，静脉及胆管的分布情况。结果 66个肝脏中，66.7%的Ⅷ肝段，100%的V肝段（部分或全部）通过肝中静脉回流；采用经典劈离方式的肝脏，其右半肝的第V，Ⅷ肝段静脉回流均被破坏。结论 改良劈离方式更安全可靠，在供肝大小适合的情况下应成为临床劈离式肝移植的首选术式。

The experimental study of human liver-split

Objective To select a safe and feasible way by comparing the two main styles of splitting liver transplantation classical splitting and modified splitting.Methods In order to compare the distribution of artery, vein and bile duct of all segments of liver, 58 formaldehyde fixed livers and 8 fresh livers were divided into two groups. One group was subjected to classical splitting and the other group to modified splitting. Results Among 66 livers, 66.7?% of the segment VIII and 100?% of the segment V (all or some) drained to middle hepatic vein. In classical splitting group, the vein drainage of 5th and 8th segments of right graft was destroyed.Conclusion Modified splitting is safer and more reliable than classical splitting, so the former is the first choice when the size of donor liver is suitable.
