title: [A Case of Traumatic Carotid Cavernous Fistula Treated with a Single Procedure Selective Transarterial Embolization Using Hydrogel Coils].
abstract: A 30-year-old man was admitted to our hospital after a bicycle accident. Proptosis, conjunctival congestion, and orbital vascular bruit appeared one month after the accident. Neuroradiological findings showed a traumatic carotid cavernous fistula(CCF). CCF is a pathologic arteriovenous shunt between the carotid artery and cavernous sinus. A detachable balloon was the standard device used for treatment of high flow direct CCF, although it is currently unavailable in Japan. Therefore, many other constructive strategies are being developed. We successfully treated this patient with single transarterial embolization using hydrogel coils. Hydrogel coils are platinum coils coated with polymeric water gels, and can be used at a prospect of delayed volume expansion. In our case, the patency of the internal carotid artery was maintained using the coils, and the symptoms improved shortly after the procedure. The use of hydrogel coils for the treatment of CCF appears to be safe and effective.
