Dural Arteriovenous Fistula (dAVF) Treatment Options
Treatments for dAVF — including surgery — vary based on the type of dAVF (low- or high-risk).
Treatment options may include:
Embolization treatment for dAVF
Embolization is a minimally invasive treatment.
It involves passing a small catheter via a blood vessel in the groin through connecting blood vessels of the dAVF. Your neurosurgeon will then deposit glue, coils or, most commonly, Onyx (an occlusive substance) to close off the fistula.
Gamma Knife® radiosurgery for dAVF
Gamma Knife radiosurgery uses highly focused radiation in a single session to target the dAVF.
The effect isn't immediate, but it's a safe treatment option especially for people with low-risk dAVFs that can’t have complete embolization.
Neurosurgical disconnection dAVF treatment
In cases of high-risk dAVFs where embolization isn’t an option, surgical disconnection can effectively cure the fistula.
Your neurosurgeon will perform a craniotomy over the dAVF and remove the affected lining of the brain (dura) and draining vein.
