Abstract
The inferior petrosal sinus (IPS) is the most commonly used transvenous approach to obliterate the carotid-cavernous fistula (CCF). We presented a case of direct CCF was successfully embolized through contralateral jugular vein via the prevertebral vein at the level of the atlanto-occipital membrane. Because of the confluence of the caudal end of the IPS and the prevertebral vein at the medial side of the hypoglossal canal, the transvenous route through the ipsilateral jugular vein was failed. Transcirculation approach via the prevertebral vein at the level of the atlanto-occipital membrane seems to be the choice when venous access is available.
