摘　　要：目的观测右半肝门静脉的分支分型规律以及对右半肝分叶分段的影响,为诊断和治疗肝脏疾病提供更为详尽的形态学资料。方法搜集100例无肝病的成人64-MSCT增强扫描肝门静脉期数据,利用CT自带的GE ADW 4.5工作站对其进行三维重建,观察右半肝门静脉的分支分型,统计归类,测量其主干及主要分支的相关数据并与解剖学数据比较。结果右支主干的长度为(21.77±10.35)mm,直径为(9.10±1.66)mm;右后叶支的长度为(30.35±14.2)mm,直径为(5.97±1.18)mm;右前叶支的长度为(24.18±6.39)mm,直径为(6.37±1.31)mm。右支主干共分为6型,右前叶支分支中P8分3型;P5分3型;右后叶支可分为5型,P6和P7均可分为5型。右半肝门静脉分支可跨过肝中静脉分布至左半肝,右前叶同时也接受左半肝的门静脉血供。结论右半肝门静脉长度、直径的变动范用较大。右半肝血供复杂,其分支分型使得右半肝分叶分段具有不规则性,直接影响到右半肝手术边界的精确判定。Objective To observe the branch classification rule of the right hepatic portal vein and the influence on the segmentation of the right hepatic lobe,providing more detailed morphological data for the diagnosis and treatment of liver diseases.Methods The 64-MSCT enhanced scan data of the hepatic portal vein in 100 adults without hepatic disease were reconstructed in three dimensions using the GE ADW 4.5 workstation that comes with the CT.The branch classification of the right hepatic portal vein was observed,statisticallyclassified,and the main and main points were measured.The relevant data of the branch was compared with the anatomical data.Results The length of the right main branch is(21.77±10.35)mm and the diameter is(9.10±1.66)mm;the length of the right posterior branch is(30.35±14.2)mm and the diameter is(5.97±1.18)mm;the length of the right anterior branch is(24.18±6.39)mm and the diameter is(6.37±1.31)mm.The right main branch can be divided into 6 types.In the right front leaf branch,P8 is divided into 3 types;P5 is divided into 3 types;the right posterior branch can be divided into 5 types,and both P6 and P7 can be divided into 5 types.The branch of the right hepatic portal vein can cross the middle hepatic vein and distribute to the left hepatic lobe.The right anterior lobe also receives the blood supply of the left hepatic portal vein.Conclusion The length and diameter of the right hepatic portal vein vary greatly.The blood supply of the right hepatic liver is complicated and its branch classification makes the right hepatic lobe segmentation irregular which directly affect the accurate determination of the right hepatic surgical boundary.
