Neuro-ophthalmic features of carotid cavernous fistulas and their treatment by endoarterial balloon embolisation

Abstract

The neuro-ophthalmic features of 11 traumatic carotid cavernous fistulas and their successful occlusion by endoarterial balloon embolisation is reported. Significant improvement in all neuro-ophthalmic signs and symptoms occurred following treatment, however, ocular motility deficits persisted in 7 patients. All 11 fistulas were occluded and the patency of the internal carotid artery was preserved in 9 patients. Though the internal carotid artery was sacrificed in 2 patients there were no permanent sequelae. Transient complications of the procedure occurred in 2 patients.
