Abstract: Arteriovenous malformations are high-flow vascular malformations， which might occur in both the soft tissue and jaw bone of oral and maxillofacial region. Clinical manifestations include skin discolorization with hyperthermia， pulsation and bruits of the involved area. Sometimes， AVMS might be associated with severe disfiguration， ulceration and bleeding. At present， embolotherapy， sclerotherapy， and surgical procedures are commonly used to deal with this intractable lesion. In this section， the technical aspects of embolo/sclerotherapy are introduced， and the main points of treatment and outcomes are discussed according to the angioarchitecture of the AVMs， both in soft tissue and in jaw. Generally， embolo or sclerotherapy should be the primary treatment for soft tissue AVMs， except when the lesion is associated with severe cosmetic problems. For a majority of central AVMs， superselective embolization and surgical curettage under hypotensive anesthesia is considered as the optimal treatment， particularly for those with episodes of severe bleeding.
