title: Arteriovenous malformation of the mandible presented as massive upper gastrointestinal bleeding: report of one case.
abstract: Arteriovenous malformation is an uncommon cause of upper gastrointestinal bleeding in children. It should be taken into consideration when a child has upper gastrointestinal bleeding because without proper management, it might be fatal. We report a 10-year-old boy whose initial presentation was massive hematemesis and impending shock. After angiography, arteriovenous malformation (AVM) of the mandible was found and treated with embolization. This 10-year-old boy also had chicken pox during admission. Case reports regarding AVM of dental arches in literature are reviewed and the proposed managements are summarized. Embolization combined with surgical excision might be the optimal way to manage AVM of dental arches.
