Percutaneous radiofrequency ablation for the treatment of liver neoplasms in the caudate lobe left of the vena cava: electrode placement through the left lobe of the liver under CT-fluoroscopic guidance.

Five hepatocellular carcinomas and one liver metastasis located in the caudate lobe left of the inferior vena cava were successfully treated by radiofrequency (RF) ablation by placing the RF electrode into each tumor through the left lobe of the liver under the CT-fluoroscopic guidance. All tumors were free of enhancement on dynamic contrast-enhanced CT during the mean follow-up period of 6.3 months. There were no major complications related to the procedures.
