450 - Surgical Management of Capillary Malformation-Arteriovenous Malformation (CM-AVM) Syndrome of the left mandible and RASA1 mutation in a Pediatric Patient

Abstract: This case report details the ongoing care of a now 7 year old female with a history of Capillary Malformation-Arteriovenous Malformation (CM-AVM) Syndrome of the left mandible and RASA1 mutation. The patient presented initially at age 3 to the outpatient pediatric dentistry clinic as a referral from the departments of otolaryngology and interventional radiology for evaluation and assessment of her dentition as it related to the malformation. Intraosseous arteriovenous malformation in the mandible is a rare congenital vascular abnormality associated with abnormal connection between arteries and veins. An understanding of the clinical and radiographic features of this condition, can prevent iatrogenic injuries such as traumatic tooth extractions which have sequelae of severe bleeding and possibly death. This report will detail the patient’s medical and dental history, current oral health status, and ongoing treatment needs.
