Multipolar percutaneous us-guided radiofrequency ablation of hepatocellular carcinoma(HCC)

Objectives: Multipolar radiofrequency ablation (RF) allows to extend the volume of coagulation without loss of energy from the lesion; up to three bipolar RF probes can be placed simultaneously within the tumor. The aim of this study was to prospectively evaluate the effectiveness of the multipolar RF device, and whether the extended volume of necrosis achieved might worsen the functional hepatic reserve in cirrhotic patients with (HCC). Methods: Twenty one nodules of HCC in 21 patients (16 males; 48–78yrs) were treated using a multipolar RF ablation system under ultrasonographic guidance. Fourteen patients had…
