摘要

目的  观测门静脉肝内段二级分支的形态特征和分支分布规律,为诊断和治疗肝脏疾病提供更为详尽的解剖学及影像学资料。 方法  100例无肝病的成人多排螺旋CT(64-MSCT)增强扫描肝门静脉获得数据,利用CT自带的GE ADW 4.5工作站对其进行三维重建,并结合50例成人肉眼无病变尸肝对肝门静脉进行解剖剥离,观测及比较肝门静脉分支规律并采集相关数据进行统计学分析。  结果  影像重建和大体解剖的近第1肝门处肝门静脉内径分别为(11.20±1.48)mm和(10.86±2.01)mm;左、右支主干夹角分别为(93.58±24.03)°和(105.59±13.82)°;左支横部长分别为(29.50±6.51)mm和(23.90±5.29)mm,中点内径分别为(7.70±1.55)mm和(7.43±1.09)mm;右支主干长分别为(21.77±10.35)mm和(20.63±6.59)mm;中点内径分别为(9.10±1.66)mm和(9.26±1.77)mm。依据肝门静脉的分支情况可将其分为4型。  结论  肝门静脉变异情况并不少见,其分支的直径与夹角等均存在一定的变化,在肝外科手术实施时,对门静脉主干分支各型应给予高度的重视。

Abstract

Objective  To observe the morphological characteristics and branch distribution of the primary branch of portal vein in the liver, and provide more detailed anatomical and imaging data for the diagnosis and treatment of liver diseases.   Methods  One hundred adults without liver illness scaned by 64-MSCT enhanced scaner data of hepatic portal vein, were reconstructed by GE ADW 4.5 workstation with CT. Combined with 50 cases of adult human without pathological cadaveric liver, the hepatic portal vein was anatomy stripped. The branching rules of hepatic portal vein were observed and compared, and relevant data were collected for statistical analysis.   Results  Image reconstruction and gross anatomy of the internal diameter of the portal vein at the first hepatic portal were (11.20±1.48) mm and (10.86±2.01) mm, respectively. The angles of the left and right branches were (93.58±24.03)° and (105.59±13.82)°; the length of pars transverses on the left stems were (29.50±6.51) mm and (23.90±5.29) mm, and the midpoint inner diameter were (7.70±1.55) mm and (7.43±1.09) mm, respectively; the right branch trunk length were (21.77±10.35) mm and (20.63±6.59) mm; the inner diameter of the midpoint were (9.10±1.66) mm and (9.26±1.77) mm, respectively. According to the branch of the hepatic portal vein, it could be divided into 4 types.   Conclusion  The variation of hepatic portal vein is not uncommon. There are certain changes in the diameter and angle of the branches. When the liver surgery is performed, the main branches of the portal vein should be given high attention.
