Transvenous embolization of a dural arteriovenous fistula of the laterocavernous sinus through the pterygoid plexus.

We present a novel access for transvenous embolization of a dural arteriovenous fistula of the laterocavernous sinus through the external jugular vein and the pterygoid plexus. The anatomy of the laterocavernous sinus is reviewed, and its clinical implications discussed in light of the case of a patient whose management was modified after identifying this anatomical variation.
