title: Direct-puncture embolization of intraosseous arteriovenous malformation of jaws.
abstract: OBJECTIVE
  Our goal was to report our experience with direct-puncture embolization of intraosseous arteriovenous malformations (AVMs).
  
  
  METHODS
  Three cases of AVM in the mandible and 2 cases of AVM in the maxilla comprised this study group. The patients were embolized with fiber coils through direct puncture, and the coils were placed directly into the center of the intraosseous lesion, in some cases in conjunction with polyvinyl alcohol foam and N-butyl-2-cyanoacrylate through vascular access.
  
  
  RESULTS
  The acute arterial bleeding was controllable in 3 patients. The other 2 patients had pericoronal oozing bleeding and a warm soft pulsative mass on the left face, respectively; their symptoms and signs improved greatly. The pericoronal oozing of blood in all patients disappeared during a 3- to 13-month follow-up, and new bone formation was found on the follow-up radiography.
  
  
  CONCLUSIONS
  The embolization of the AVM of jaws by direct percutaneous puncture in conjunction with endovascular therapy is effective and safe, but longer follow-up is required to determine the true efficacy of this method of treatment.
