Value of multislice spiral CT simulation model of hepatic carcinoma in interventional therapy

Objective To explore the value of multislice spiral CT (MSCT) simulation model of hepatic carcinoma in interventional therapy.Methods Enhanced MSCT was performed in 42 cases of primary hepatic carcinoma before interventional procedure.The simulation model was established with postprocessing software to demonstrate the supply blood arteries of tumor, hepatic arteriovenous shunt, tumor thrombosis of portal vein.The schemes of interventional therapy were worked out ac-cording to the findings of MSCT simulation model of hepatic carcinoma and the time of transcatheter procedure recorded.Results With respect to display quality in the supply arteries of tumors and its trend of 42 patients, there was good or fair correlation between MSCT simulation model of hepatic car-cinoma and DSA.MSCT simulation model of hepatic carcinoma could clearly demonstrate the suppl-ying blood vessels of tumors including hepatic arterial anomalies(5 cases), diphragmic arteries (3 ca-ses), left gastric arteries (2 cases), intercostal arteries (2 cases) and inferior suprarenal arteries (2 cases).There was no significance in demonstrating hepatic arteioportal shunt and tumor thrombosis of portal vein between MSCT simulation model of hepatic carcinoma and DSA (P>0.05).The duration of transeatheter procedure was lower than that of the routine procedure.Conclusion MSCT simula-tion model of hepatic carcinoma has high clinical value and it can clearly display the supplying arteries of tumors and its trend, markedly reduce the duraiton of transcatherter and operative procedure and obtain complete embolization.
