Dural arteriovenous fistula

Abstract

Dural arteriovenous fistulas (DAVF) are abnormal connections between dural arteries and venous sinuses or cortical veins. They can have a wide range of clinical presentations and are prone to hemorrhage. Management strategies are dependent on clinical presentation and location. Stereotactic radiosurgery has been demonstrated to be a valid treatment option, especially for patients with fistulas that are considered at low risk of hemorrhage or cavernous sinus location. Obliteration rates in most studies range from 40% to 85%, with radiation-induced side effects reported in 0-23%. This chapter provides an overview of SRS for DAVF and compares it to other treatment modalities.
