Interventional treatment for unresectable hepatocellular carcinoma

Figure 3 Multiple hepatocellular carcinomas with significant arterioportal shunts in a 71-year-old woman. Enhanced computed tomography (CT) imaging revealed viable hepatocellular carcinomas (HCCs) (A, black arrow) with lipiodol deposit HCCs (A, white arrows). Common hepatic arteriography in the arterial phase (B) demonstrated HCC with significant arterioportal shunts (B, arrows), consisting of P8 and P4. Common hepatic arteriography under balloon occlusion of the portal vein branches of P8 and P4 showed an opacified tumor with non-visualized arterioportal shunts (C). CT images 2 mo after transcatheter arterial chemoembolization under occlusion of the 2 portal vein branches (D) demonstrated a dense lipiodol deposit in the HCC and a complete response, according to modified Response Evaluation Criteria in Solid Tumors.
