Abstract Background Radio frequency ablation RFA has been accepted clinically as a useful local treatment for hepatocellular carcinoma HCC . However intrahepatic recurrence after RFA has been reported which might be attributable to increase in intra-tumor pressure during RFA. To reduce the pressure and ablation time we developed a novel method of RFA a multi-step method in which a LeVeen needle an expansion-type electrode is incrementally and stepwise expanded. We compared the maximal pressure
