Traumatic Carotid Cavernous Fistula Caused by Intradural Aneurysm Rupture: A Case Report.
1970-01-01
Traumatic carotid carvenous fistula (CCF) associated with cerebral aneurysm is a rare condition. Early detection of the traumatic cerebral aneurysm (TCA) before traumatic CCF occlusion is difficult, largely because of steal phenomenon of the fistula, masking by complex venous drains and a nearby parent artery, and a latent period of the TCA. In addition, traumatic CCF caused by a combined aneurysm rupture is an extremely rare condition. It is a dangerous condition in which treatment should be performed immediately or even on an emergency basis. A 31-year-old man developed traumatic CCF after traffic accident. Cerebral angiography revealed a direct CCF communicated with an intradural aneurysm on the origin of right posterior communicating artery (PcomA). Successful transarterial coil embolization was achieved after consecutive two trials.
