Treatment of recanalization of maxillary and mandibular arteriovenous malformations in 4 pediatric patients

Abstract

Abstract: PURPOSE: This study reviewed our experience in treating recanalization of maxillary and mandibular arteriovenous malformations in 4 pediatric patients. METHODS: Four patients with maxillary or mandibular arteriovenous malformations (AVMs) were included in this study. All patients had undergone multidisciplinary treatment of AVM at least 26 months before this review, including superselective intra-arterial embolization combined with bone wax packing(BWP). Computed tomographic angiography and digital subtraction angiography (DSA) were performed to confirm the presence of recanalization. Superselective intra-arterial embolization combined with BWP and tooth extractions were performed in the patients with AVM recanalization. RESULTS: After confirmation of the recanalization of AVM by DSA, the patients were treated with superselective intra-arterial embolization combined with BWP and tooth extractions (if necessary). All patients were followed up for 5 to 14 months, with an average of 9.5 months. The outcome for all patients was good, and no patient complained of pulsatile sensation or hemorrhage after treatment. CONCLUSIONS: In the treatment for recanalization of maxillary and mandibular AVMs, reapplication of superselective intra-arterial embolization, combined with BWP, remains necessary.
