Clinical Study of Embolization of Arteriovenous Malformation in the Oral and Maxillofacial Region

Den-gao Liu, DDS, PhD/Xu-chen MA, DDS, PhD

Objective: To evaluate the value of embolization on arteriovenous malformations (AVM) in the oral and maxillofacial region and to investigate the efficacy of several different embolic materials. Clinical Materials and Methods: 10 cases with AVMs, including 5 AVMs mainly in the soft tissue and 5 intraosseous lesions, were embolized. Clinical and angiographic effects were analyzed during the 3 to 16 months follow-up. Results: In the 5 cases embolized without other treatment, 1 case was embolized 3 times, 3 cases twice, and 1 case once. In these cases, postembolization angiograms revealed complete or nearly complete disappearance of the lesions. In the other 5 cases, embolized before surgery intraoperative bleeding was significantly decreased. All these patients were free of recurrence during follow-up. Among the materials employed, NBCA seemed to offer a better result. Conclusions: Embolization may serve as the primary therapy for some AVMs in the oral and maxillofacial region, or as a routine preoperative adjunct for patients with severe intraosseous or disfiguring AVMs.
