    Abstract:
    A patient with spontaneous carotid-cavernous sinus fistula, who developed central retinal vein occlusion (CRVO) after interventional surgery, was reported. A 78-year-old woman was admitted with symptoms of right abducens palsy and conjunctival injection. Digital subtraction angiography (DSA) revealed bilateral carotid cavernous sinus fistulas supplied by dural branches of the carotid arteries. After embolization of the feeding arteries and the right cavernous sinus using PVA and platinum coils respectively, her symptom improved gradually. Six months after the embolization, she was readmitted because of blurred vision and abducens palsy on the left side. Engorgements of the cavernous sinuses and draining veins, and the shunt flow of the fistula were much less on DSA than those seen previously, but ophthalmologic studies showed an impending central retinal vein occlusion (CRVO) in her left eye. Prognosis of CRVO is generally poor. We discussed the mechanism of CRVO occurring after interventional surgery for CCF and the tactics for preventing it, and early detection of its development.
