AIM:To work out an individualized lipiodol dose in transcatheterarterial chemoembolization (TACE) for large hepatocellularcarcinoma (HCC) according to its blood supply evaluated by CT.METHODS:One hundred patients with large HCC (morethan 8 cm in diameter) were studied by multidetector helicalCT.Patterns of blood supply of HCC were divided intosufficient blood supply,poor blood supply,mixed bloodsupply and arteriovenous (A-V) shunt.The dose of ultra-fluid lipiodol was determined by diameter and blood supplytype of HCC.Patients were divided into two groups (50 caseseach):lipiodol perfusion group and iodized oil perfusiongroup according to tumor diameter and the blood supplytype of tumor.RESULTS:The confirmation and effective rates were 82%,84% in the first group and 36%,46% in the second group(P<0.01).CONCLUSION:A relatively individualized lipiodol dose maybe determined according to the blood supply pattern andthe tumor diameter by CT imaging.
