title: Transarterial Onyx embolization of sagittal sinus dural arteriovenous fistulae.
abstract: We report four patients (1 woman and 3 men) with sagittal sinus dural arteriovenous fistulae (DAVF) treated by Onyx embolizations via the middle meningeal artery. Anatomic cure and clinical cure were achieved in all the patients. The fistulae were located in the middle and posterior parts of the sagittal sinus. By Cognard classification the fistulae were: type I - one, type IIb - one, and type IV -two. All these four patients underwent a clinical and angiography follow-up, which confirmed complete cure. Based on this experience, we hypothesize that sagittal sinus DAVFs can be cured using a transarterial endovascular approach.
