The valuation of multi-slice spiral CT in diagnosis of hepatocellular carcinoma with portal vein tumor thrombus and interventional treatment
Objective To explored the 256-slice spiral CT in the diagnosis of hepatocellular carcinoma with portal vein tumor thrombus(PVTT) and its clinical valuation of the interventional treatment. Methods 68 inpatients of hepatocellular carcinoma with portal vein tumor thrombus were examined by 256-slice spiral CT liver multi-phase enhanced scanning. Post-processing methods includes maximum intensity projection(MIP), multi-planar reconstruction(MPR) and volume rendering(VR). 29 cases accepted digital subtraction angiography and hepatic artery chemotherapy embolization. Observed the 128-slice spiral CT imaging and DSA. Results PVTT imaging fingdings of the trunk or branch expansion of the portal vein, portal vein intra luminal defect, enhanced scanning showed varying degree strengthen, including CTPV 17 cases, abnormal liver parenchyma perfusion 21 cases and APS 25 cases. The 29 cases accepted DSA examination and TACE showed that the tumor feeding artery, abnormal blood vessels and PVTT lesions consistent with DSA. Conclusion 256-slice spiral CT liver multi-phase enhanced scanning can accurately diagnose the evaluation of hepatocellular carcinoma with PVTT, hemodynamic changes, and it has important clinical value to the interventional treatment.
