Dural arteriovenous fistulas (DAVFs) are fistulas connecting the branches of dural arteries to dural veins or a venous sinus. Osteodural fistulas are a rare subset of this group of diseases. We wish to report a rare case of an osteodural arteriovenous fistula at the foot of the superior ophthalmic vein (SOV), treatment of which required an unusual surgical approach via the orbit and SOV. Though access for endovascular treatment via the SOV for treatment of caroticocavernous fistulas is reported, the external approach is relatively infrequently performed, outside Europe and the Americas, with this being the first reported procedure from the Indian subcontinent. We wish to explain the steps of this unusual surgical access and highlight the salient precautions and pitfalls in the technique.
硬脑膜动静脉瘘（DAVFs）是连接硬脑膜动脉分支与硬脑膜静脉或静脉窦的瘘管。骨硬脑膜瘘是这类疾病中罕见的一种。我们希望报告一例罕见的位于眼上静脉（SOV）根部的骨硬脑膜动静脉瘘病例，其治疗需要通过眼眶和SOV采用一种不同寻常的手术入路。尽管有报道称可通过SOV进行血管内治疗来处理海绵窦瘘，但在欧洲和美洲以外地区，这种外部入路相对较少实施，而这是印度次大陆首次报道的此类手术。我们希望解释这种不同寻常的手术入路步骤，并强调该技术中突出的注意事项和陷阱。
