Abstract: PURPOSE : To evaluate the clinical effect and safety of radiofrequency ablation (RF) combined with digital subtraction angiography (DSA) -guided percutaneous ethanol sclerotherapy for refractory arteriovenous malformations(AVMs) in oral and maxillofacial region and to investigate its feasibility. METHODS : A retrospective review of patients, medical and imaging records was performed. Seven patients (4 males,3 females) with craniofacial arteriovenous malformations underwent staged RF combined with DSA-guided percutaneous ethanol sclerotherapy between March 2014 and April 2016. RESULTS : Six of 7 patients were cured,1 had no response. The therapeutic outcome was considered effective in 6 patients (85.7%). No major complications occurred. CONCLUSION S: RF with percutaneous ethanol sclerotherapy under DSA has the potential for curing refractory AVMs in oral and maxillofacial region, which may become an effective and safe tool for AVM management.
