Feeding artery ablation before radiofrequency ablation for hepatocellular carcinoma may reduce critical recurrence

Background and Aim Percutaneous radiofrequency ablation (RFA) is a minimally invasive and curative local treatment for hepatocellular carcinoma (HCC). However, serious concerns remain regarding critical recurrences such as metastasis, dissemination, and/or seeding due to RFA. In August 2006, we introduced selective feeding artery ablation before tumor ablation to reduce the risk of critical recurrence by blocking tumor blood flow. The aim of the...
