    Abstract:
    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)
