Three cases of mixed internal and external carotid-cavernous fistula (CCF) were successfully treated with embolization of feeders from the external carotid artery (ECA) and focal irradiation to the cavernous sinus (CS). Cases 1 and 2 were females, 63 and 69 years old respectively, both with spontaneous left CCF. Case 3 was a 55 year old male with posttraumatic left CCF. Symptoms of case 1 were double vision, left chemosis and exophthalmos; those of case 2 were double vision, left retroobital pain, left forehead dysesthesia and
blurred vision
; and case 3 complained of double vision, left chemosis, left exophthalmos and pulsatile tinnitus. In all three cases, angiography disclosed left CCF fed by ipsilateral dural branches from the internal maxillary artery (IMA) and the internal carotid artery (ICA). In case 1, small branches from the ascending pharyngeal artery also fed the CS. In cases 2 and 3, feeders from the ECA were arising only from branches of the IMA. In case 3, hypertrophy of the meningohypophyseal trunk was visible. In cases 1 and 2, although the CS was opacified, feeders from the ICA were not clearly visible. Embolizations of branches of the IMA were performed in all cases using
Ivalon
under selective catheterization. In case 1, symptoms partially improved, but in cases 2 and 3, visual symptoms were transiently aggravated. Focal irradiation to the CS was done with total doses of 30, 30 and 40 Gy each for cases 1, 2, and 3 respectively. In case 1, clinical symptoms gradually improved about one third way through irradiation.(ABSTRACT TRUNCATED AT 250 WORDS)

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.
