Multislice spiral CT in interventional therapy of hepatocellular carcinoma

Objective To investigate the value of multislice spiral CT (MSCT) in interventional therapy of the hepatocellular carcinoma(HCC) emphasising on transcatheter hepatic arterial chemoembolization (TACE). Methods MSCT were performed in 54 cases of HCC before interventional procedure, CT findings of hepatic artery phase, portal venous phase and hepatic venous phase were observed respectively, among which CTA were done in 12 cases, and the anatomy of celiac artery and its branches were observed. The schemes of interventional therapy were worked out according to the findings of MSCT. Results MSCT showed 225 lesions, 10 cases of tumor thrombosis in portal vein, 1 case of hepatic arteriovenous shunt , and 13 cases of hepatic arterioportal shunt. There was no significant difference between MSCT and DSA in positive rate of in showing number of tumor or tumor thrombosis in portal vein ( P 0.05), but the 3D construction of celiac artery branches in CTA was better than that in DSA, while angles between celiac artery and abdominal aorta in MSCT were more convenient than that in DSA. MSCT showed 5 cases of hepatic artery original abnormality, in according with that in DSA. Conclusion MSCT is of importance for guidance of interventional therapy of the hepatocellular carcinoma.
