Surgical management of petrosal dural arteriovenous fistulas

Dural arteriovenous fistulas (DAVFs) are rare with a low incidence. Tentorial DAVFs account for 10%-15% of all intracranial DAVFs and are associated with an aggressive clinical course. Petrosal DAVFs are a subtype of tentorial DAVFs and account for approximately 26% of tentorial DAVFs. They are supplied by the marginal tentorial artery or external carotid artery branches and drain into the petrosal vein and/or the superior petrosal sinus. Petrosal DAVFs may be challenging to treat endovascularly, while surgical management is often relatively safe and effective. Here the authors present two cases of surgically managed petrosal DAVFs.
