[Arteriovenous angioma in the maxillofacial region]

Congenital arteriovenous angiomas are seldom observed in the maxillofacial region. Because of their hemodynamic-active Shunt volumina, they tend towards progressive and difforming increase in volume. Clinical differentiation from other angiodysplasias is obtained by serial angiography. Therapy in the facial region consists of either a direct and mostly subtotal interruption of the short circuit by embolization of the AV shunts and selective ligature of the hemodynamically important vessels, or in a total removal of the involved region by extensive plastic-reconstructive measures. The latter particularly applies to hemodynamic shunt volumina with general cardiovascular feedback, grave recidivating bleeding, important defiguration and recidives after selective ligature operation.
