  • Title: Clinical study of embolization of arteriovenous malformation in the oral and maxillofacial region.
    Author: Liu D, Ma XC.
    Journal: Chin J Dent Res; 2000 Nov; 3(3):63-70. PubMed ID: 11314538.
    Abstract:
    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.
