Common systems of radiofrequency ablation (RFA) are monopolar devices which require grounding pads on the thighs in order to close the electrical circuit. Bipolar RFA does not require grounding pads, because both electrodes are located on one probe and alternating current circuit is confined within the target tissue. In this paper we report on the first clinical application of a new ablation device which enables both, bipolar (1 probe) and multipolar (up to 3 internally cooled probes simultaneously) radiofrequency ablation. We report on bi- and multipolar applications in liver tumors (9 patients), osteoid osteoma (2 patients) and renal cell cancer (1 patient).
常见的射频消融（RFA）系统是单极设备，需要在大腿上放置接地垫以闭合电路。双极RFA不需要接地垫，因为两个电极位于一个探头内，交变电流电路局限于目标组织内。在本文中，我们报告了一种新型消融设备的首次临床应用，该设备能够进行双极（1个探头）和多极（最多同时使用3个内部冷却探头）射频消融。我们报告了该设备在肝肿瘤（9例患者）、骨样骨瘤（2例患者）和肾细胞癌（1例患者）中的双极和多极应用情况。
