Abstract

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).
