摘要: 目的    应用256排螺旋CT行上腹部血管造影,描述右半肝门静脉与肝静脉的CT表现、两者解剖关系和肝分段的再定义,探讨其临床意义。  方法    随机收集100例受检者CT平扫及三期增强扫描图像,观察三维重建后右半肝门静脉分支、肝静脉属支的分布情况,并对相关数据进行统计学分析。  结果    门静脉分布情况:S5段分为4型,A型66%,B型10%,C型8%,D型16%;S6段分为6型,A型56%,B型15%,C型4%,D型17%,E型4%,F型4%;S7段分为3型,A型73%,B型23%,C型4%;S8段分为5型,A型67%,B型3%,C型2%,D型8%,E型20%。肝静脉分布情况:肝左静脉、肝中静脉、肝右静脉分别汇入下腔静脉有45%,肝左静脉与肝中静脉形成共干汇入下腔静脉有55%;36%出现肝右下后静脉,11%肝右静脉细小,由发达的肝中静脉代偿性引流右半肝;15%肝中静脉主干位于门静脉主干分叉处上方,41%肝中静脉位于Rex-Cantlie线右侧。肝静脉与门静脉解剖关系分为4型,以A型最多,占64%,D型最少,占3%。  结论    右半肝肝静脉和门静脉解剖形态复杂多样,门静脉主干变异时肝静脉与门静脉空间分布也随之发生改变,对肝个体化手术的顺利实施具有影像学指导意义。

Abstract: Objective    To describe the CT features of the right hepatic portal vein and hepatic vein by upper abdominal angiography with 256-slice spiral CT, and to explore the anatomical relationship and the redefinition of liver segmentation, so as to explore its clinical significance.    Methods    One hundred cases who were randomly collected were examined with plain CT scanning and three-phase enhanced CT scanning. The distribution of right hepatic portal vein and the branches, hepatic vein and the branches after 3D reconstruction were observed, and the relevant data were statistically analyzed.    Results    The distribution of portal vein: S5 segment could be divided into 4 types. There were 66 cases of A type, 10 cases of B type, 8 cases of C type, and 16 cases of D type. S6 segment could be divided into 6 types, A type 56 cases, B type 15 cases, C type 4 cases, D type 17 cases, E type 4 cases, F type 4 cases . S7 segment could be divided into 3 types, A type 73 cases, B type 23 cases, C type 4 cases. S8 segment could be divided into 5 types, A type 67 cases, B type 3 cases, C type 2 cases, D type 8 cases, E type 20 cases. The distribution of hepatic vein: 45 cases of LHV, MHV and RHV were imported into IVC respectively. Fifty-five cases of LHV and MHV formed common trunk and were imported into IVC. IRHV was found in 36 cases, 11 cases of RHV were small with compensatory blood supply to the right liver by developed MHV. The main MHV trunk was located above the main bifurcation of the portal vein in 15 cases, and the MHV was located right of the Rex-Cantlie line in 41 cases. In this paper, the spatial position relationship between hepatic vein and portal vein was divided into four types. Type A has the most (accounting for 64%) and type D has the least (accounting for 3%).    Conclusions    The anatomical features of the hepatic vein and portal vein in the right part of the liver is complex and diverse. The spatial distribution of hepatic vein and portal vein also change when the main portal vein is mutated. It has imaging guiding significance for the smooth implementation of individualized liver surgery.
