Dural AVM

It is known as a dural arteriovenous fistula. They are vascular anomalies consisting of arteriovenous shunts located between the layers of the outer membrane of the brain called the dura, and are often fed from the branches of the main vessels of the brain before entering the dura. Generally speaking, they are not true AVMs and are classified as direct fistulas.

In general, the main balls in the dura are located around the vessels. They constitute 10-15% of all intracranial AVMs. It is seen in women with a rate of 61-66% and patients are 40-50 years old. It is rarely seen in children.

It may present as tinnitus, a murmur at the back of the head, impaired vision, and headache. Bleeding risk is less than AVMs.


Embolization, which is the task of filling the inside of the lesion with angiographical method, may be the first option in the treatment. Or it contributes to surgery and reduces the risk of serious bleeding. Radiosurgery (Gamma knife, Cyber kinife, etc.) can be used after embolization.
