Abstract

We performed percutaneous radio frequency ablation (RFA) therapy by two-step insertion method using VirtuTRAXTM (GE Healthcare, USA) instrument navigator. Subjects were 16 patients (23 nodules) with hepatocellular carcinoma. VirtuTRAXTM position sensor was attached to the hilt of 14-gauge outer needle. In all cases, we could perform 17- gauge Cool-tip RFA without the positional gap between the virtual tract and the actual needle which was caused by the deflection of the needle. The reasons without causing the positional gap were that the outer needle was more rigid than Cool-tip needle, and that it was inserted using initial insertion of a 21-gauge guided needle. RFA by two-step insertion method using VirtuTRAXTM is suggested to be more safe and effective than conventional RFA.
