Diagnostic Value of Enlargement of Anterior Space of the Right Branch of Portal Vein in the Early Cirrhosis at Multi-detector Row CT / 实用放射学杂志

ABSTRACT

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 B 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)mm 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.
