摘 要:目的探讨肝硬化门静脉高压患者食管及胃底静脉曲张程度与侧枝循环多个指标CT征象的依存性关系。方法门静脉高压组(A组)30例,正常对照组(B组)30例。CT测量2组的门静脉(PV)、胃冠状静脉(GCV)直径,胃底-脾门区静脉血管截面总面积,与胃镜结果进行多元线性回归分析。结果PV直径为(16.17±2.44)mm(A组)及(12.42±1.53)mm(B组),Beta=0.39。GCV直径为(6.22±2.41)mm(A组)及(3.39±1.03)mm(B组),Beta=0.85。胃底-脾门区静脉血管截面总面积:A组和B组分别为(5.14±5.96)mm2和(1.32±0.98)mm2,Beta=1.90。多元线性回归方程:y=0.39X1+0.85X2+1.90X3。结论胃底-脾门区静脉血管截面总面积作为一种新的CT检测指针对评价门静脉高压具有较高价值。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 varieosis in gastro - spleuic region were(5.14 ± 5.96 ) cmz in group A and (1.32 ± 0.98 ) cmz in group B, Beta = 1.90. Multiple linear regression equation : y = 0.39X1 + 0.85Xz + 1.90X3 Conclusion The total CSA of varicosis in gastro - splenic region is a useful CT feature in evaluating portal hypertension.
