Dural Arteriovenous Fistulas: Review of Imaging Findings and Endovascular Treatment Strategies

This article aims to review the imaging diagnosis and endovascular treatment of DAVFs. Case examples are used to present characteristic noninvasive and invasive diagnostic imaging findings. Important treatment considerations that assist in planning and implementing appropriate endovascular treatment are reviewed. Educational objectives of the article include the ability to readily identify and describe the multimodality imaging findings present in intracranial and spinal DAVFs and to discuss various endovascular treatment strategies, including transarterial approaches, transvenous approaches, and combined surgical/endovascular therapy.
