Abstract
BACKGROUND: In case of cavernous sinus dural arteriovenous fistula, transvenous embolization of the cavernous sinus via the inferior petrosal sinus is generally sufficient. However, when inferior petrosal sinus access is challenging, various alternative approaches have been reported, with corresponding difficulties and risks. CASE REPORTS: We report the management of two cases of life-threatening cavernous sinus dural arteriovenous fistula revealed by a typical cavernous sinus syndrome. Conventional approaches were unsuccessful, and a direct microsurgical approach was performed, with catheterization of the superior ophthalmic vein. This combined approach safely accessed the cavernous sinus, and obtained complete occlusion of the fistulae by Onyx® embolization. CONCLUSIONS: This procedure could be an interesting alternative option in the treatment of cavernous sinus dural arteriovenous fistula when conventional approaches are not possible.
