Summary
Radiofrequency (RF) ablation is effective for smaller hepatic hemangiomas (5-10 cm) with a low complication rate. However, RF ablation is not recommended for large hepatic hemangiomas (≥10 cm) due to a high incidence of complications.
Area of Science:
- Hepatology
- Interventional Radiology
- Surgical Oncology
Background:
- Hepatic hemangiomas are benign vascular tumors.
- Large hemangiomas (≥5 cm) can cause symptoms or enlargement.
- Radiofrequency (RF) ablation is a minimally invasive treatment option.
Purpose of the Study:
- To evaluate the feasibility, safety, and efficacy of RF ablation for large hepatic hemangiomas (≥5 cm).
Main Methods:
- Retrospective analysis of 36 patients with 41 hepatic hemangiomas (≥5 cm).
- Patients were treated with RF ablation via laparoscopic or percutaneous approaches.
- Outcomes assessed included technical success, complications, ablation completeness, symptom relief, and recurrence.
Main Results:
- RF ablation was technically successful in all patients.
- Complications occurred in 22 patients (54%), with 2 major complications (Grade III/IV) in the ≥10 cm group.
- Complete ablation was achieved in 93% of hemangiomas (<10 cm: 100%; ≥10 cm: 82%).
- Symptom relief was observed in all treated patients.
- No recurrence or enlargement of residual tumors was noted during follow-up.
Conclusions:
- RF ablation is a safe and effective treatment for hepatic hemangiomas <10 cm.
- RF ablation is not recommended for hepatic hemangiomas ≥10 cm due to a high complication rate.
