Analysis of the Factors of Esophageal-Gastric Varices in Portal Hypertension / 实用放射学杂志

ABSTRACT

Objective To evaluate the correlation of the CT features of the collateral circulation and the degree of esophageal-gastric varices in patients with portal hypertension caused by hepatic cirrhosis.Methods 30 cases with portal hypertension were in group A and 30 healthy people were in group B.The diameter of portal vein(PV),gastriccoronary vein(GCV),the total cross-sectional surface area(CSA) of varices in gastro-splenic region were measured in both group A and B,the results and endoscopic signs were analysed with multiple linear regression.Results The diameters of PV were(16.17?2.44) mm in group A and(12.42?1.53) mm in group B,Beta =0.39. The diameters of GCV were(6.22?2.41)mm in group A and (3.39?1.03) mm in group B,Beta =0.85. The total CSA of varicosis in gastro-splenic region were(5.14?5.96) cm2 in group A and (1.32?0.98) cm2 in group B, Beta =1.90. Multiple linear regression equation y=0.39X1+0.85X2+1.90X3 Conclusion The total CSA of varicosis in gastro-splenic region is a useful CT feature in evaluating portal hypertension.
