背景在劈离式肝移植过程中，必须认识到变异的动脉解剖结构并进行适当的处理，以确保两种移植物的完整血管供应。我们描述了一个副右肝后动脉，起源于左肝，并通过门静脉分支后面。在离体肝劈离过程中检查了37个连续肝脏。一个异常的右副动脉起源于左肝动脉被确定在肝门的高。解剖变异描述和说明亚甲蓝注射和动脉造影。结果在37例劈肝手术中有2例出现异常。两个右叶的异常动脉均被切除。在门静脉分叉后分离时应小心，以排除副段肝右动脉。如果存在，肝脏可能不适合在不损害右叶的情况下分离，除非左肝动脉可以在副血管起源的远端分离。
Background. Variant arterial anatomy must be recognized and appropriately managed during split liver transplantation to ensure complete vascular supply to both grafts. We describe an accessory posterior right hepatic artery, arising from the left and passing behind the portal vein bifurcation.Methods. Thirty-seven consecutive livers were examined during ex vivo liver-splitting procedures. An abnormal right accessory artery arising from the left hepatic artery was identified high in the porta hepatis. The anatomical variant is described and illustrated by methylene blue injection and arteriography. Results. The anomaly was encountered in 2 of 37 split liver procedures. The two right lobes with the abnormal artery were discarded.Conclusion. Care should be taken during dissection behind the portal vein bifurcation to exclude an accessory segmental right hepatic artery. If present, the liver may not be suitable for splitting without compromising the right lobe, unless the left hepatic artery can be divided distal to the origin of the accessory vessel.
