  • Title: Bilateral carotid-cavernous fistula following head trauma: Possible worsening of brain injury following balloon catheter occlusion?
    Author: Hantson P, Espeel B, Guérit JM, Goffette P.
    Journal: Clin Neurol Neurosurg; 2006 Sep; 108(6):576-9. PubMed ID: 15890443.
    Abstract:
    A 68-year-old woman developed right pulsatile exophtalmos in the early course of facial and head trauma. Investigations by visual evoked potentials suggested the presence of a bilateral prechiasmatic lesion. Intraocular pressure rapidly increased and a high-flow carotid-cavernous fistula was evident at carotid angiography. Immediately after the treatment of the right fistula by balloon embolisation, a systolic bruit was noted over the left eyeball and angiography disclosed the presence of a left carotid-cavernous fistula that was treated by the same approach. The patient developed brain oedema leading to death and we postulated that reestablishment of normal cerebral perfusion after abrupt closure of the fistulas may have played a deleterious role.
