Abstract：
Isolated superior petrosal sinus dural arteriovenous fistula (SPSdAVF) is a rare condition for which transvenous embolization is a safe treatment, even if accessing the isolated sinus can be challenging. A 39-year-old female patient with dizziness and right facial palsy underwent magnetic resonance imaging, revealing a venous infarction at the posterior fossa and a dural arteriovenous fistula. Digital subtraction angiography showed an isolated SPSdAVF. The shunt point was posterior to the isolated superior petrosal sinus, and the shunt flowed only through the petrosal vein. Contrast-enhanced magnetic resonance imaging showed thrombosis at the anterior segment of the superior petrosal sinus. Transvenous embolization was successfully performed via the thrombosed anterior segment of the superior petrosal sinus without associated complications. This case shows that transvenous embolization through a thrombosed superior petrosal sinus is an alternative treatment option for isolated SPSdAVF.
摘要：
孤立上岩窦硬脑膜动静脉瘘（SPSdAVF）是一种罕见的疾病，经静脉栓塞是一种安全的治疗方法，即使进入孤立的鼻窦可能是具有挑战性的。一名39岁的女性患者头晕和右面神经麻痹，接受了磁共振成像，显示后颅窝静脉梗死和硬脑膜动静脉瘘。数字减影血管造影显示孤立的SPSdAVF。分流点位于孤立的岩上窦后方,分流管只流过岩静脉.对比增强磁共振成像显示上岩窦前段血栓形成。经血栓形成的上岩窦前段成功进行了经静脉栓塞，无相关并发症。此病例表明，通过血栓形成的上岩窦经静脉栓塞是孤立的SPSdAVF的替代治疗选择。
