Endovascular treatment of indirect carotid-cavernous fistula via thrombosed superior ophthalmic vein in patient with trapped sinus [Tuzaklanmi{dotless}ş sinüslü bir olguda i̇ndirekt karotiko-kavernöz fistülün tromboze süperior oftalmik ven yoluyla endovasküler tedavisi]

In the endovascular treatment of indirect carotid-cavernous sinus fistulas (ccf's) when access to the cavernous sinus via transfemoral approach could not be obtained due to various reasons (vascular variation,thrombosis,trapped sinus),superior ophthalmic vein (sov) is the main way that can be used. sov provides direct access to the cavernous sinus. however,sov may be thrombosed in some cases. in these cases the recognization and catheterization of sov is quite diffucult although successful catheterization is possible with the angiojet passing through thrombosis in case of which thrombosis is segmental. herein we aimed to report a 58- year- old woman who underwent embolization of indirect ccf (barrow type d) through thrombosed sov with liquid agent onyx 18 because of trapped sinus. clinical features,endovascular embolization technique and results are discussed.
