Abstract
We report a case of hepatocellular carcinoma (HCC) with chronic hepatitis C virus (HCV) infection, which was successfully treated with percutaneous radiofrequency ablation (RFA) under live three-dimensional (3D) echocardiography guidance. Recently, it was reported that live 3D echocardiography was able to enhance the efficacy of catheter-based endomyocardial injection since the 3D images made it possible to observe the target from multiple directions so that it guided more accurately. A 63-year-old Japanese man had an HCC nodule of 3.0 cm in diameter at the S8 region of the liver. Here we applied live 3D echocardiography during RFA therapy with a LeVeen needle electrode. The echocardiography guidance allowed for easier and accurate approach for needle puncture. The guidance was also effective to confirm whether an enough safety margin for the nodule was obtained. Thus, live 3D echocardiography appears to safely guide RFA needles by accurate targeting for HCC nodule, providing real-time visualization when combined with echocardiography contrast.
