Endovascular treatment of a traumatic dural arteriovenous fistula of the superior sagittal sinus using dual lumen balloon microcatheter

Endovascular treatment for a patient with posttraumatic dural arteriovenous fistula (DAVF) of the superior sagittal sinus (SSS). A) Left internal carotid artery angiogram before embolization showing the DAVF supplied by the anterior falx artery; B, C and D) Lateral (B&D) and anteroposterior (C) view of left external carotid artery (ECA) angiogram before embolization showing the DAVF of SSS with bilateral cortical venous reflux; E) Unsubtracted image showing the Scepter balloon catheter navigated close to the fistulous point for Onyx injection (arrow head indicating the balloon markers, arrow indicating the distal tip); F) Unsubtracted image showing the Onyx cast extending to the proximal draining vein after embolization; G) Post-embolization angiogram of the left common carotid artery showing complete disappearance of the fistula. H) Post-embolization angiogram of the right ECA showing complete disappearance of the fistula.
