title: Dental arcade arteriovenous fistulas: from diagnosis to treatment with emphasis on the role of endovascular or percutaneous treatment: single centre experience.
abstract: OBJECTIVE
  Dental arcade arteriovenous fistula (DA-AVF) are rare. The purpose of this study was to understand the angioarchitecture of these lesions, changing strategies of endovascular treatment and to analyse the best therapeutic option which will allow normal skeletal development especially in children.
  
  
  METHODS
  Retrospective study of all the patients of DA-AVF managed at our centre over the last 16 years. Detailed analysis of the clinical features, the imaging findings, endovascular treatment and angiographic outcomes was done.
  
  
  RESULTS
  Total of six patients were treated. 5 were in the mandible and one in the maxilla. Transarterial glue embolization was done in 3 patients and direct puncture of the intraosseous venous pouch in 2. Transarterial Onyx was used in 2 patients through dual lumen balloon catheter. Overall cure was achieved in 5 out of 6 patients (83%).
  
  
  CONCLUSIONS
  High index of suspicion is required to diagnose it on panoramic radiographs. CT/MR/CTA can lead to early diagnosis. Transarterial Onyx embolization using dual lumen balloon catheter is a promising technique & allows excellent penetration of Onyx into the intraosseous venous pouch.
