A Case of De Novo Anterior Condylar Dural Arteriovenous Fistula Long after Curative Transvenous Embolization of Contralateral Anterior Condylar Arteriovenous Fistula

Figure 2

(a) Left external carotid angiogram demonstrates dural arteriovenous fistula around left jugular valve. Dural arteriovenous fistula is mainly fed by meningeal branches of the left ascending pharyngeal artery (arrowhead) and drained to left internal jugular vein, bilateral vertebral venous plexus through the left anterior condylar vein. Left cavernous sinus and transverse-sigmoid sinus are refluxed. Anterior condylar confluence is depicted as expanded venous pouch (arrow). (b) Right common carotid angiogram demonstrated obliteration of dural arteriovenous fistula in the right anterior condyle confluence. Coil mass inserted five years ago is depicted (arrowhead). Right ascending pharyngeal artery feeds dural arteriovenous fistula in the contralateral anterior condylar confluence.
