To describe initial clinical experience with bipolar radiofrequency ablation (RFA) for symptomatic giant hepatic haemangiomas.
Four consecutive patients with a large-volume, symptomatic hepatic cavernous haemangioma of >10 cm were treated with bipolar RFA during laparotomy with ultrasound guidance. Complications were carefully noted. Clinical and radiological effectiveness were evaluated comparing baseline with 3 and 6 months follow-up of symptom assessments and upper abdominal magnetic resonance imaging (MRI) or computed tomography (CT).
RFA was successfully performed for all four giant haemangiomas. No major complications were observed. Peri-procedural shrinking was remarkable and intermediate-term volume reduction ranged from 58-92% after 6 months. Symptom relief after 6 months was complete in two patients and considerable in the other two.
Preliminary results suggest intra-operative bipolar RFA to be a safe, feasible, and effective technique for treatment of giant symptomatic hepatic cavernous haemangiomas.
描述使用双极射频消融（RFA）治疗有症状的巨大肝血管瘤的初步临床经验。
连续 4 例体积大、有症状的>10cm 肝海绵状血管瘤患者，在超声引导下剖腹手术中接受双极 RFA 治疗。仔细记录并发症。通过对上腹部磁共振成像（MRI）或计算机断层扫描（CT）的症状评估和 3 个月和 6 个月的随访比较，评估临床和影像学疗效。
所有 4 例巨大血管瘤均成功进行了 RFA。未观察到主要并发症。围手术期收缩明显，6 个月后体积缩小率为 58-92%。2 例患者在 6 个月后完全缓解症状，另外 2 例患者有明显改善。
初步结果表明，术中双极 RFA 是治疗有症状的巨大肝海绵状血管瘤的一种安全、可行且有效的技术。
