Heat sink during radiofrequency ablation of a hepatocellular carcinoma abutting a large hepatic cystic lesion.

摘要

Hepatocelhilar carcinoma (HCC) is the most common primary hepatic tumor and one of the most common cancers worldwide. Surgical resection of hepatocellular carcinomas and liver transplant are considered to be the gold standard treatments. Radiofrequency ablation is a standard therapeutic option for patients who are not candidates for surgical resection (1).Technical end points vary among commercially available RF ablation systems. The LeVeen RF ablation system (Boston Scientific, Natick, Massachusetts) detects the electrical impedance (Ohm) of the hepatic tissue during the delivery of RF energy.
