Intracranial Dural Arteriovenous Fistula: Microneurosurgery Basics and Tricks

Intracranial dural arteriovenous fistulas (DAVFs) are acquired lesions characterized by a region of abnormal arteriovenous fistulous connection within the dura. DAVFs contribute to 10–15% of all AVM intracranially as reported by Newton et al. from 1969 [1]. In common population the probable rates were 0.15–0.29 per 100,000 people per year [2, 3]. Median age of DAVF patients is between 50 and 60 years, but it may present at any age [4, 5].
