Presentation transcript:

A 55-year-old patient with a history of intraparenchymal hemorrhage on CT of the head (A) related to a right transverse–sigmoid dural arteriovenous fistula (DAVF). A 55-year-old patient with a history of intraparenchymal hemorrhage on CT of the head (A) related to a right transverse–sigmoid dural arteriovenous fistula (DAVF). Anteroposterior view (B) of right external carotid artery injection demonstrated an aggressive DAVF, with a parallel venous channel, a venous pouch (*) and cortical venous reflux (CVR) (arrowhead). A transvenous Onyx infusion (C) is performed under a blank roadmap condition. The Onyx cast (double arrows) correlated to the parallel venous channel (single arrow) in (B). Final lateral angiographic view (D) after transarterial and transvenous Onyx infusion demonstrated a very small feeder from the posterior auricular feeder that continued to supply the CVR (arrow). Microsurgical disconnection was performed. (Used with permission from Barrow Neurological Institute). Yin C Hu et al.
