Abstract:
Objective To evaluate the efficacy, safety and complications of minimally invasive percutaneous radiofrequency ablation(PRFA) therapy for hepatic cavernous hemangioma(HCH). Methods Twelve patients with total 15 HCHs (2.5cm to 9.5cm) were treated by using RF-2000 generator and 10-needle LeVeen electrode percutaneously guided by B-ultrasound. Tumors larger than 3cm were treated by multiple overlapping ablations that encompassed the entire lesions as well as an approximately 0.5cm rim of normal liver tissue. Results The procedures were successful and the patients recovered well without the complications of bleeding or bile leakage after mean 48-month follow up period. Spiral CT scanning showed that the contrast enhancement was disappeared within the lesions or at their periphery in all cases. The mean diameter of the ablated HCHs reduced 68%. Conclusion The results suggested that PRFA therapy was a minimally invasive, simple, safe, and effective approach for treating HCHs in selected patients.
