摘要
Background: Hepatic hemangioma is a common benign liver tumor. The majority of cases are asymptomatic and require no specific treatment. The aim of this study was to evaluate the feasibility, safety and efficacy of microwave ablation (MWA) for symptomatic or enlarging giant hepatic hemangioma (>= 10 cm). Methods: From December 2013 to June 2016, 12 patients with giant hepatic hemangioma (>= 10 cm) underwent ultrasound-guided percutaneous MWA, and ablation-related complications were observed. All patients were followed up with magnetic resonance or enhanced CT imaging at one month postoperatively to evaluate efficacy. Results: This study included a total of 13 giant hepatic hemangiomas (mean: 11.7 +/- 1.6 cm) in 12 patients who initially underwent 16 sessions of MWA; three lesions were treated with two sessions of planned ablation. The average ablation time for a single hepatic hemangioma was 39.0 +/- 14.4 minutes. Two patients had acute postoperative non-oliguric renal insufficiency without intra-abdominal hemorrhage, liver failure or other complications. Initially, complete ablation was achieved in ten lesions in nine patients (76.9%, 10/13). One patient underwent a second session of MWA at 5 months postoperatively due to fast growing residual tissue; complete necrosis was achieved after treatment. The remaining two cases did not receive any invasive treatment due to small residual volumes. The total complete ablation rate was 84.6% (11/13). Conclusion: Image-guided MWA is a safe, feasible, effective treatment for giant hepatic hemangioma; these findings may open a new avenue for treatment.
