Study on Dynamic Enhanced Multislice Spiral CT: Hepatocellular Carcinoma with Portal Vein Invasion

Objective To evaluate the formative mechanisms and the dynamic enhanced multi-slice spiral CT(MSCT) features and their clinical significance of hepatocellular carcinoma(HCC)with portal vein invasion(PCI).Methods Three hundred and sixteen patients with HCC were received dynamic enhanced MSCT scan of the liver,of which eighty-eight patients with PCI were found and the MSCT signs were analyzed with DSA findings.Results All the 88 patients with PCI had related positive CT signs in dynamic enhanced scan.The results were as follows: 72 cases of tumor thrombus of the portal vein(TTPV),36 cases of cavernous transformation of portal vein(CTPV) among the 72 cases TTPV,60 cases of arterioportal shunt(APS),16 cases of abnormal perfusion of hepatic blood flow. Conclusion MSCT provides an important examining tool for the diagnosis of HCC with PCI,and is of important significance in the study on the formative mechanisms and the treatment of HCC with PCI.
