[A case report of the carotid cavernous fistula treated by endovascular embolization using interlocking detachable...

To treat a carotid cavernous fistula, endovascular embolization using a detachable balloon technique is generally performed to close the fistula. However, the balloon sometimes becomes detached accidentally before reaching the orifice, so it is not an ideal device for closing a fistula from point of view of safety. This time, we performed transarterial endovascular embolization using Interlocking Detachable Coils (IDC) for a symptomatic CCF, and obtained a good result. A 32-year-old male, who was injured in a traffic accident developed symptoms of CCF after four months: edema and pain in the right conjunctiva, bruit at the right orbit. Angiography showed CCF, the orifice of which was located at the transitional portion of C4 and C5. IDC embolization was performed; three IDCs were placed at the cavity of the fistula through the orifice, and complete occlusion of the fistula was confirmed on angiography. Postoperative clinical course was good and symptoms were improved.
