The type of venous drainage of a direct carotid-cavernous fistula is an important issue to consider for the endovascular therapeutic decision. In case of an inadequate posterior drainage associated with a good anterior drainage, the facial vein is a useful alternative. The exclusive embolization with ethylene vinyl alcohol (EVOH Onyx), arterial and/or venous via the internal carotid artery (ICA) occlusion has been used successfully, in a few cases until now. Nevertheless, the use of this method through anterior transvenous approach has not been previously described. Presented here is the case of a 13-year-old female patient with left posttraumatic carotid-cavernous fistula, with predominant anterior drainage, as well as carrier of traumatic occlusion of the contralateral ICA. The treatment was by means of a transvenous approach with transient occlusion of the left ICA.
