Case report: A male patient with a left carotid-cavernous sinus fistula (CCSF) and two previous attempts of embolization via the femoral vein was treated with embolization through the superior ophthalmic vein (SOV).
Discussion: The main modality of treatment for CCSF is intervention radiology. This aims to occlude the fistula via an arterial route, through the cavernous sinus, or via a venous route, through the inferior petrosus sinus. However, the CCSF is also accessible through the SOV.
