Evaluation Of 64MSCT Hepatic And Portal Vein Angiography In Diagnosis The Portal Hypertension Due To Hepatic Cirrhosis

Evaluation of 64MSCT hepatic and portal vein angiography in diagnosis the portal hypertension due to hepatic cirrhosisObjective To investigate the value of 64MSCT Scan in the early hepatic cirrhosis together with portal hypertension.Methods Comparison the 64MSCT portography and hetophlebography between the early and the advanced stage hepatic cirrhosis together with portal hypertension by retrospective studies, which are proved by pathologic diagnosis and/or clinical diagnosis. Then summarize the data and evaluate the 64MSCT Scan in the early hepatic cirrhosis together with portal hypertension.Results The PV (Portal Vein) is wider in cirrhotic groups than control group(P<0.01), except the diameter of PV (Portal Vein)in decompensate cirrhosis and compensated cirrhosis group, the parameters are not statistic significance in different cirrhotic grade(P>0.05). The diameter of PV (Portal Vein) in control group is less than 12mm. The inner diameter of RHV (Right Hepatic Veins) is significant higher in compensated cirrhosis group, which is wider than 10mm, but is opposite in the decompensate cirrhosis group companied with lower enhanced index vessel density. The PV/RHV of decompensate cirrhosis group is 1.77±0.06, which is statistic significance higher (P<0.05)than that of the control group(PV/ RHV<1.47±0.08) and the compensated cirrhosis group (PV/RHV< 1.32±0.08). By using the Post-processing maximum intensity projection (MIP) observation software to display the PV and RHV:The PV and RHV of control group were shown to be clear, smooth and glossy, nature course branches of PV can be observed above 5 grades. In the compensated cirrhosis group we can find branches of PV between 3 to 4 grades. The RHV of the decompensate cirrhosis group can hardly be observed more than 1 grade. Meanwhile the intrahepatic branches of PV in decompensate cirrhosis group were looking thickening, stiff and twist courses and the intrahepatic branch of PV could be displayed no more than 3 grades.Conclusion The 64MSCT portography and hetophlebography can clearly demonstrate the diameter changes of PV and RHV. It has great diagnostic value in the early hepatic cirrhosis together with portal hypertension.
