dc.description.abstractOBJECTIVE: To evaluate the altered findings of hepatic arteriography after radiofrequency (RF) ablation of hepatocellular carcinoma which can potentially influence subsequent transcatheter arterial chemoembolization. MATERIALS AND METHODS: Hepatic arteriograms of 26 index hepatocellular carcinomas in 24 patients treated only by RF ablation (M:F = 22:2, mean age 55 years), in which hepatic arteriography was performed before and after RF ablation, were retrospectively compared for the altered findings. RESULTS: The altered findings of hepatic arteriography after RF ablation of the hepatocellular carcinoma were arterio-portal shunt (n = 3), periablational enhancement (n = 5), varied caliber of the feeding artery to the index tumor (n = 12) among which eight decreased, and occlusion of an adjacent arterial branch (n = 8). Residual unablated or locally progressed tumor was not detected in post-RF ablation arteriography (n = 5) due to the arterio-portal shunt (n = 2) or the periablational enhancement (n = 3). The possibility of not detecting the residual unablated or locally progressed tumor was higher within 24 weeks after RF ablation (Mann-Whitney test, P = 0.041). CONCLUSION: The findings of hepatic arteriography are altered after RF ablation, and the altered findings may increase the difficulty in performing super-selective transcatheter arterial chemoembolization due to undetected tumor staining, decreased caliber, or occlusion of the feeding artery.-
