    Abstract:
    BACKGROUND: To evaluate the efficacy and safety of transarterial bleomycin sclerotherapy of early-stage facial arteriovenous malformation (AVM). METHODS: A retrospective review was performed of patients who underwent bleomycin sclerotherapy for early-stage AVM (Schobinger stage I or II) in a single-referral vascular anomalies center. Bleomycin was slowly infused transarterially with flow control techniques to prolong the effects of bleomycin. Procedure details, AVM characteristics, and previous treatments were reviewed. Initial therapeutic outcomes were determined by 5 categories using both radiological and clinical findings in a 6-month follow-up. Further follow-up outcomes were reviewed to evaluate the long-term efficacy and safety of the treatment. Procedure-related complications were also analyzed. RESULTS: Nineteen patients (mean age 22.4 ± 14.0 years, 14 females) with 31 sessions of sclerotherapies were enrolled. All AVMs were Cho-Do classification type III (type IIIa [n = 13], type IIIb [n = 2], and type IIIa+b [n = 4]). Patients received a mean of 1.6 (range, 1-4) sessions of treatment. The mean cumulative bleomycin dose was 23,600 IU ± 14,500 (range, 8000 - 60,000 IU). The results showed that 14 patients (74%) were responsive to transarterial bleomycin sclerotherapy, including complete response (n = 3), marked improvement (n = 1), and partial improvement (n = 10). The remaining 5 (26%) showed no response. During a mean follow-up of 32.6 months, 5 (26%) showed slight progression compared with 6-month outcomes and 14 (74%) were stable. There were only 2 minor complications [hyperpigmentation (n = 1) and cellulitis (n = 1)]. CONCLUSIONS: Transarterial bleomycin sclerotherapy using flow control techniques can be a safe and feasible alternative treatment option for facial early-stage AVM.
