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.
岩下窦（IPS）是最常用于闭塞颈动脉海绵窦瘘（CCF）的经静脉入路。我们报告了一例直接 CCF 通过对侧颈内静脉经寰枕膜处的椎前静脉成功栓塞的病例。由于 IPS 的尾端和椎前静脉在舌下神经管的内侧汇合，因此经同侧颈内静脉的经静脉入路失败。当静脉入路可行时，经寰枕膜处椎前静脉的经颅循环入路似乎是一种选择。
