[Radiofrequency for the treatment of liver tumors].

Radiofrequency is performed with thin electrodes that are placed in the center of a tumor under ultrasonographic guidance. Radiofrequency waves induce ionic agitation which destroys neighboring tissues by heat. The most recent equipment can produce necrosis of 4-cm diameter areas. Efficacy is enhanced by blocking intrahepatic blood flow which naturally refreshes the liver parenchyma. The techni...

Ultrasound-Guided Intraoperative Radiofrequency Ablation and Surgical Resection for Liver Metastasis from Malignant Gastrointestinal Stromal Tumors

Objective To evaluate the effectiveness, safety, and feasibility of intraoperative radiofrequency ablation (IORFA) under ultrasound guidance for the treatment of liver metastases from gastrointestinal stromal tumors (GISTs). Materials and Methods From August 2009 to February 2017, 24 patients with liver metastases of GISTs underwent IORFA, 14 underwent concurrent IORFA and primary GIST resect...

Comparative analysis of Laparoscopic versus open surgical radiofrequency ablation for malignant liver tumors

BACKGROUNDS/AIMS This study aims to evaluate the comparative effectiveness of two surgical approaches on the treatment outcomes of radiofrequency ablation (RFA) for malignant liver tumors. METHODS Fifty-seven patients with malignant liver tumors, hepatocellular carcinoma, cholangiocarcinoma and liver metastases, who were candidates for RFA, underwent laparoscopic or open surgical treatments. ...

Virtual Radiofrequency Ablation of Liver Tumors

In the last few years, radiofrequency ablation has become one of the most promising techniques to treat liver tumors. But radiologists have to face the difficulty of planning their treatment while only relying on 2D slices. We present here a realistic radiofrequency ablation simulation tool, coupled with a 3D reconstruction and visualization project. They help radiologists to have a better visu...

Radiofrequency Ablation of Miscellaneous Solid Tumors Excluding Liver Tumors - 121616

In radiofrequency ablation (RFA), a probe is inserted into the center of a tumor and the noninsulated electrodes, which are shaped like prongs, are projected into the tumor; a heat is then generated locally by a high-frequency, alternating current that flows from the electrodes. The local heat treats the tissue adjacent to the probe, resulting in a 3 cm to 5.5 cm sphere of dead tissue. The cell...
