Type D Traumatic Carotido-cavernous Fistula due to Selective Transection of the Inferolateral Trunk(ILT). Diagnosis and Endovascular Treatment.

SUMMARY: A minority of traumatic carotido-cavernous fistulas (CCF) are of the indirect variety, and then usually supplied only by meningeal branches of the ipsilateral external carotid artery (Type C).We describe a case of a Type D CCF due to traumatic injury of the inferolateral trunk (ILT), and describe its angiographic features and endovascular management through both the external and internal carotid arteries following a failed transvenous approach.
