aroticocavernous fistulas (CCF) are abnormal arteriovenous anasto- moses between the internal carotid artery (ICA) and the cavernous sinus. 1 CCF can be classified according to the aetiology (spontaneous or traumatic), flow rates (high or low speed), or anatomical characteristics (direct or indirect arterial supply). 1 The most widely used classification is the one made according to the arterial supply to CCF. A traumatic arteriovenous fistula is most frequently seen in the craniofacial area injuries. It is easy to identify arteriovenous fistulas occurring between the ICA, their branches, and the cavernous sinus with the characteristic symptoms of visual loss, ex- ophthalmos, orbicular pulse, extraocular muscle paralysis, and an orbital blowout fracture. 2 In this article, a patient suffering from a traumatic carotid- cavernous sinus fistula treated with the Brooks method was presented. Turkiye Klinikleri J Neur 2018;13(3):73-8 73 Brooks Method for the Treatment of a Traumatic Caroticocavernous Fistula and a Historical Perspective to Endovascular Interventions: A Case Presentation and a Literature Review ABSTRACT A caroticocavernous fistula is an abnormal communication between the internal or external carotid arteries and the cavernous sinus. This case report presents a patient with a carotid- cavernous sinus (CCSF) fistula, diagnosed and treated at a time when the endovascular interventions were not commonly performed. The diagnosis was made by evaluating the clinical symptoms and with a conventional percutaneous angiography of the right internal carotid artery (ICA). The pa- tient was treated with the embolization of CCSF with a “free” piece of muscle (Brooks Method). The clinical symptoms of the patient were evaluated and noted before, during, and after the operation. The benefits of new technological products and devices on patient recoveries were reviewed with respect to the literature.

Bu makalede; endovasküler girişimlerin etkili olarak uygulanmadığı bir dönemde, klinik bulguları ve konvansiyonel perkütan sağ karotis anjio- grafi tekniği ile tanısı konan bir olguya, cerrahi olarak, internal karotis arter yolu ile serbest adale embolizasyonu (Brooks tekniği) uygulandı. Olgunun ameliyat öncesi, esnası ve sonrası klinik bul- gularında olan düzelme ile yeni teknoloji ürünlerinin ve cihazlarının hasta iyileşmesine olan katk- ıları gözden geçirildi.
