OBJECTIVE: Radiofrequency (RF) ablation is an accepted nonsurgical treatment of hepatic hemangiomas, but with an appreciable complication rate. Our study aimed to assess the safety and efficacy of RF ablation, administered with either multitined expandable electrodes or with internally cooled cluster electrodes, in the treatment of large (≥10 cm diameter) hepatic hemangiomas. METHODS: We retrospectively reviewed our sequential experience of treating 43 large hepatic hemangiomas in 42 patients with RF ablation/multitined expandable electrodes or with RF ablation/internally cooled electrodes. Twenty-two hemangiomas in 21 patients were treated with expandable electrode (multitined electrode group), and 21 hemangiomas in 21 patients were treated with internally cooled cluster electrode (internally cooled electrode group). RESULTS: Among the 43 large hepatic hemangiomas, 27 subcapsular lesions were treated by a laparoscopic approach, and 16 lesions located in liver parenchyma were treated by a computed tomography-guided percutaneous approach. In the multitined electrode group, RF ablation treatment was performed in all 21 patients in 1 session. In the internally cooled electrode group, 18 patients were treated by RF ablation in 1 session, and 3 patients, with ≥14.0-cm single hemangioma, were treated with RF ablation in 2 sessions. Complete ablation was achieved in 81.8% (18/22) and 90.5% (19/21) in the multitined electrode group and the internally cooled electrode group, respectiv...
