Dural Arteriovenous Fistulas (DAVFs)

Dural arteriovenous fistulas (DAVFs) are anormal bridges between an artery and a vein in the dural covering of  the brain or spinal cord. DAVFs usually take origin because of a blockage of one of the brain’s venous sinuses. Most DAVFs have no identifiable cause, although some may result from traumatic head injury, previous brain surgery, infections, tumors, or venous thrombosis.

Dural Arteriovenous Fistulas Treatment

The most direct and effective treatment for DAVF usually is micro-neurosurgical disconnection of the artery to the vein by obliterating the feeding arteri(es).  Endovascular procedure or gamma knife radiosurgery are other alternative treatment options.
