One-step endovascular treatment of bilateral traumatic carotid-cavernous fistulae with atypical clinical course.

Traumatic carotid-cavernous fistula (TCCF) is a rare neurovascular pathologic entity. The bilateral form occurs even rarer and given the potential risk for both optic tracts presents an urgent indication for quick and effective treatment. We present a patient with a bilateral Barrow type A TCCF with a fulminant development of symptoms, who was successfully treated with bilateral detachable balloons in a single session endovascular procedure. The patient experienced complete relief of symptoms, however the complete neurological deficit in the left optic nerve was persistent.
