NAVEENJAYAKUMAR et al. Intra-osseous vascular malformation in the maxilla. Rev Esp Cirug Oral y Maxilofac [online]. 2009, vol.31, n.6, pp.392-396. ISSN 2173-9161.

Intraosseous arterio-venous malformations (AVM) in the maxillofacial region are rare clinical entities. They have a wide range of clinical presentation and are not always diagnosed without a surprise. Treatment of these lesions has always been a challenge to the surgeon due to extreme vascularity and the high recurrence rate. The case presented is that of an intraosseous arterio-venous malformation in the maxilla that started as gingival bleeding and routine radiographic examinations were inconclusive. Surgical excision and bone wax packing was performed there were no recurrences during 1-year of follow-up. Vascular malformations may be considered in differential diagnosis of gingival bleeding with inconclusive dental radiographs.
