Although dural arteriovenous fistulas (DAVFs) occur in any structure that is covered by the dura mater, DAVFs at the posterior condylar canal have not been reported. We present a DAVF that involves the posterior condylar canal and drains into the posterior condylar vein and the occipital sinus, which was treated by selective transvenous embolization. Knowledge of venous anatomy of the craniocervical junction and careful assessment of the location of the arteriovenous fistula can contribute to successful treatment.
尽管硬脑膜动静脉瘘（DAVF）可发生于硬脑膜覆盖的任何结构，但髁后管处的DAVF尚未见报道。我们报告一例累及髁后管并引流至髁后静脉和枕窦的DAVF，该病例通过选择性经静脉栓塞治疗。了解颅颈交界区的静脉解剖结构并仔细评估动静脉瘘的位置有助于治疗成功。
