摘要
目的根据肝内门静脉的走行分布,对门静脉的右后支进行分类,为影像学和肝脏外科提供资料。方法采用100例正常的活体肝移植供肝影像资料,研究右后叶肝内门静脉的走行和分布。结果 100例资料中门脉的右后支呈弓型的34例,呈两支型的27例,呈三支型的9例,存在右前支变异的30例。结论右后叶大约有30%在解剖学上不能完全分界,不符合Couinaud的分段方法。
Objective To evaluate the intrahepatic portal veins and hepatic veins of right posterior lobe of liver,put up a definition of hepatic segment for the imaging and liver surgery.Methods Using 100 successive sections of the upper abdomen of adult MRI enhanced images of living donor for liver transplantation.The course and division pattern of the intrahepatic portal vein and the hepatic veins,and also the relationship between them were investigated.Results Among the 100 right posterior of portal veins,arch-like pattern seen in 34 cases,two branches appeared in 27,three branches appeared in 9,variant appeared in 30.Conclusion The right posterior segments can not be identified about 30% by Couinaud's classification.
