  • Title: Pediatric intraoral high-flow arteriovenous malformation: a diagnostic challenge.
    Author: Petel R, Ashkenazi M.
    Journal: Pediatr Dent; 2014; 36(5):425-8. PubMed ID: 25303512.
    Abstract:
    Arteriovenous malformations (AVMs) are rarely reported in the dental pediatric literature. They may develop adjacent to primary molars and can be life-threatening due to their potential for massive bleeding. The most common symptom associated with documented cases of AVMs is spontaneous gingival bleeding. Other clinical signs include pain, erythematous gingiva, resorption and mobility of teeth, soft tissue discoloration, facial swelling, and asymmetry. Radiographically, AVMs are osteolytic lesions. The purpose of this report was to describe the challenge of diagnosis of a high-flow arteriovenous malformation located in the primary maxillary molar region, which was misdiagnosed as a dentoalveolar abscess adjacent to previously treated primary molars. A decision to extract a tooth with gingival swelling and associated spontaneous bleeding should be made after the differential diagnosis of a vascular malformation has been ruled out.
