RESUMEN
Conventional endovascular treatment for carotid cavernous fistula (CCF) involves a direct delivery of either coils, detachable balloon or both to the fistula with end point of CCF resolution and carotid artery preservation. But in few cases with severe laceration of carotid artery, the feasible endovascular technique applicable is by blocking the filling of fistula from cerebral circulation. This method known as trapping technique which implicates carotid artery occlusion, was performed in our present case with good result.
RESUMEN
Dural carotid-cavernous fistula (CCF) is characterized by arteriovenous communications between the meningeal branches of the internal or external carotid arteries and the cavernous sinus. Although the triad of chemosis, proptosis, and ocular bruit has been regarded as a classic sign of CCF, dural CCF often lacks these features. Dural CCF is a rare cause of ophthalmoplegia, and so it may be overlooked when the classic symptoms are absent. We report herein a case of bilateral dural CCF that presented as unilateral isolated abducens nerve palsy.
