目的探讨肝门静脉右支的形态特征和分支分布规律。方法 50例肉眼观察无病变的成人尸肝进行剥离解剖,对肝门静脉右支的形态结构进行观察,测量主干及主要分支的相关数据并进行统计学分析。结果 82.0%肝门静脉分为左﹑右两支,其成角(105.59±13.82)°,依据右支主干分支将其分为5型,其中65.8%右支主干分为右后叶支和右前叶支。右后叶支主干的分支情况亦可分为6型,主要供应Couinaud 6、7段,然6.0%的6段部分血供可来自右前叶支,2.0%全部来自右前叶支的分支。右前叶支主干,主要供应5、8段,但有36.0%的5段血供来自于右后叶支,而6.0%右前叶支发出血管走行至4段。结论肝门静脉右支主干及主要分支的类型变化较大,其分支分布直接影响到右半肝各肝段的界定,肝脏外科术前必须对其进行详细而准确的评估。
Objective To investigate the morphology and branch distribution of the right hepatic vein. Methods 50 cases of diseased adult corpses were observed with naked eye for dissection and dissection. The morphology and structure of the right hepatic vein were observed. The data of main trunk and major branches were measured and statistically analyzed. Results 82.0% of the hepatic portal vein was divided into left and right branches, which were angled (105.59 ± 13.82) °. They were divided into 5 types according to the right branch and the right branch was divided into right branch and right anterior branch support. The trunk of the right posterior branch of the branch can also be divided into 6 types, the main supply Couinaud 6, paragraph 7, while 6.0% of the 6 sections of blood supply can be from the right anterior branch, 2.0% from the branch of the right anterior branch. Right anterior lobe branch, the main supply of 5,8, but 36.0% of the 5 blood supply from the right posterior lobe branch, and 6.0% of the right anterior branch of the branch of blood vessels travel to 4 segments. Conclusions The type of the main branch and the main branch of the right hepatic vein varies greatly. The distribution of its branches directly affects the definition of each hepatic segment of the right hepatic hemangioma. The hepatic surgery must be evaluated in detail and accurately before operation.
