Endoscopic endonasal transsphenoidal direct access and Onyx embolization of a dural arteriovenous fistula mimicking a carotid-cavernous fistula: case report.

Endoscopic endonasal transsphenoidal direct access and Onyx embolization of a dural arteriovenous fistula mimicking a carotid-cavernous fistula: case report. J Neurosurg. 2020 Nov 13;:1-5 Authors: Karas PJ, North RY, Srinivasan VM, Lindquist NR, Gallagher KK, Burkhardt JK, Yoshor D, Kan P Abstract The classic presentation of a carotid-cavernous fistula (CCF) is unilateral painful proptosis, chemosis, and vision loss. Just as the goal of treatment for a dural arteriovenous fistula (dAVF) is obliteration of the entire fistulous connection and the proximal draining vein, the modern treatment of CCF is endovascular occlusion of the cavernous sinus via a transvenous or transarterial route. Here, the authors present the case of a woman with a paracavernous dAVF mimicking the clinical and radiographic presentation of a CCF. Without any endovascular route available to access the fistulous connection and venous drainage, the authors devised a novel direct hybrid approach by performing an endoscopic endonasal transsphenoidal direct puncture and Onyx embolization of the fistula.
