We describe the case of an 83-year-old woman with left-sided ophthalmoplegia. She had no family history of connective tissue disease. The computed tomography study found a dilated left cavernous sinus. The conventional cerebral panangiography confirmed the diagnosis - a direct carotid-cavernous fistula (CCF), with no evidence of ruptured aneurysm. The woman underwent endovascular treatment with coiling of the cavernous sinus in combination with application of the Onyx embolic agent in the fistula. During the first 48 hours after the embolization the local pain, exophthalmos and conjunctival injection of the left eye were significantly ameliorated. The pulsatile tinnitus on the left disappeared and the ptosis of the left eyelid partially recovered. Selective angiography is the best method for the diagnosis and classification of CCF. Currently, treatment is possible with low mortality and morbidity rates. The endovascular intervention is able to completely occlude the fistula and maintain adequate blood fl ow through the carotid artery.
