Paracavernous dural arteriovenous fistulas (pdAVFs) are extremely rare and can mimic carotid cavernous fistulas (CCFs) in both clinical presentation and imaging characteristics. Access to the venous pouch often presents the greatest challenge in the treatment of pdAVFs. Here we present a novel access technique utilizing an endoscopic endonasal transsphenoidal approach, where we directly puncture the venous pouch under both stereotactic guidance and endoscopic visualization, thereby completely embolizing a pdAVF with no alternate access (video 1). neurintsurg;15/10/1055/V1F1V1Video 1Technical video demonstrates the complete embolization of a pdAVF using an endoscopic endonasal transsphenoidal approach.
海绵窦硬膜动静脉瘘（pdAVFs）极为罕见，其临床表现和影像学特征可类似于颈动脉海绵窦瘘（CCFs）。静脉囊的入路常常是治疗 pdAVFs 最具挑战性的地方。在此，我们提出了一种新的入路技术，即利用内镜经鼻蝶窦入路，在立体定向引导和内镜可视化下直接穿刺静脉囊，从而无需其他入路即可完全栓塞 pdAVF（视频 1）。
