[Traumatic carotid-cavernous sinus fistula: a case study].

The diagnosis of carotid-cavernous sinus fistula is based on clinical findings and must be confirmed and detailed by CT scan and arteriography. If the treatment, based on embolization, is not undertaken in the emergency room, visual complications or even death may result. We give an example of a direct post-traumatic carotid-cavernous sinus fistula, stressing its clinical characteristics (ophthalmoplegia) and treatment: the advantages of arteriography and of embolization methods (most often by detachable balloon or coils, through arteries or veins).
