Radiofrequency ablation with monopolar cluster versus bipolar multipolar electrodes for the ablation of ⩾2.5 cm hepatocellular carcinoma
ABSTRACT PURPOSE To compare the effectiveness of radiofrequency ablation using a monopolar cluster and a bipolar multipolar electrode for the ablation of (⩾2.5 cm) hepatocellular carcinoma. METHODS 34 patients with a single HCC (mean size, 4.46 ± 2.3 cm; range, 2.5–7.4 cm) underwent percutaneous RFA with monopolar cluster (n = 18) or bipolar multipolar electrodes (n = 16). Technical success, ... إقراء المزيد
