摘　　要：目的评价门脉右支前间隙增宽对于早期肝硬化的诊断价值。方法回顾性分析37例经病理穿刺活检确诊的早期肝硬化患者及42例乙型肝炎患者的肝脏多排螺旋CT片，测量门脉右支前间隙及门脉右支的宽度；同时选择40例无肝脏疾患患者作为正常对照组，并测量门脉右支前间隙及门脉右支的宽度；对各组进行统计学分析。结果正常组肝脏门脉右支前间隙及门脉右支宽度分别为（5．5±2．4）mm和（11．84±1．91）mm，早期肝硬化组门脉右支前间隙及门脉右支的宽度分别为（13．6±5．8）mm和（12．36±1．97）mm，而乙型肝炎组门脉右支前间隙及门脉右支的宽度分别为（5．7±3．1）mm和（12．13±1．89）mm。经统计学分析早期肝硬化患者门脉右支前间隙宽度同乙型肝炎组及正常组门脉右支前间隙宽度的差别具有统计学意义，而门脉右支宽度的差别没有显著的统计学意义。同时，乙型肝炎组同正常对照组间门脉右支前间隙宽度的差别不具有统计学意义，2组间门脉右支宽度的差别也不具有统计学意义。结论多排螺旋CT测量门脉右支前间隙增宽，对于早期肝硬化的诊断具有较好的临床价值。Objective To evaluate the diagnostic value of enlargement of the anterior space of the right branch of portal vein in early cirrhosis. Methods 37 cases with early cirrhosis and 42 cases with type ]3 hepatitis proved by pathology as well as 40 health cases underwent MDCT examinations. The width of the anterior space of right branch of portal vein （RBPV） and the diameters of RBPV in each group were measured on CT imaging,then the results were analysed comparatively. Results The width of anterior space of RBPV and the diameters of RBPV were （5.5 ± 2.4） m m and （11.84 ± 1.91） mm in health group, （13.6±5.8） mm and （12.36 ± 61.97 ）mm in early cirrhosis group, （ 5.7 ±3.1） mm and （ 12.13 ±1.89） mm in type B hepatitis group, respectively. There were significant differences in the width of the anterior space of RBPV between three groups（P〈0. 0001）. However, there were not significant differences in the width of RBPV among these three groups（P〉0.05）. While,there were significant differences of the width of the anterior space of RBPV and the diameters of the RBPV between normal control and type B hepatitis（P〉0.05）. Conclusion CT sign of the anterior space of RBPV increased is of important value in diagnosis of early cirrhosis.
