Abstract：
BACKGROUND: The sphenoid wing dural arteriovenous fistula (AVF) is rare, and can manifest with severe symptoms, particularly in cases classified as greater sphenoid wing type. Endovascular therapy is generally employed, however, open surgical intervention could be warranted in cases with complex fistula.
METHODS: We present a case with ruptured greater sphenoid wing dural AVF (Cognard type IV), in which endovascular embolization using liquid material was performed, followed by open surgery to concurrently disconnect the fistula and evacuate the hematoma.
CONCLUSIONS: The sphenoid wing dural AVFs may be effectively cured by open surgery for fistula disconnection in conjunction with endovascular embolization.

摘要：
背景：蝶骨翼硬脑膜动静脉瘘（AVF）很少见，并可能表现出严重的症状，特别是在分类为大蝶骨翼型的情况下。通常采用血管内治疗，然而,对于复杂瘘管患者,可能需要进行开放式手术干预.
方法：我们介绍一例蝶骨大翼硬脑膜AVF破裂（IV型Cognard），其中使用液体材料进行血管内栓塞，然后进行开放手术，同时断开瘘管并清除血肿。
结论：蝶骨翼硬脑膜AVF可通过开放手术切除瘘管并血管内栓塞治疗。
