Extensive arteriovenous malformation in the face of a pediatric patient - Case report

Vascular anomalies can be academically divided into two groups: vascular tumors and vascular malformations. Among vascular malformations, we can highlight the arteriovenous malformations, a subtype of anomaly characterized by presenting a high blood flow. The diagnosis is beyond doubt a great challenge for the multi professional team involved in treating these anomalies. Imaging tests such as the ultrasonography, magnetic resonance, CT scan with contrast and angiography are extremely important for the orientation about the characteristics and hemodynamic properties of the blood vessels, for delivering predictable results and for risk reducing of complications. In this paper, we describe a rare case of extensive arteriovenous malformation in the face of a pediatric patient, its clinical characteristics and imaging manifestations as well as the satisfactory clinical results obtained with a combination of sclerotherapy and surgical excision.(C) 2014 Sociedade Portuguesa de Estomatologia e Medicina Dentaria.
