Transorbital Approach for Endovascular Occlusion of Carotid-Cavernous Fistulas: Technical Note and Review of the Literature
نویسندگان
چکیده
Carotid-cavernous fistulas (CCFs) pose an anatomically and physiologically challenging problem for clinicians. The most common method of treatment for these lesions is transvenous endovascular embolization via the inferior petrosal sinus or the facial vein. When transvenous access is not possible, an alternate approach must be devised. We describe a case example with bilateral Barrow Type B CCFs, which were inaccessible using the traditional transvenous approach. Hence, a direct transorbital approach, performed under fluoroscopic guidance, was employed to successfully obliterate the CCF. At five months follow-up, the patient was recovering without complications. This case delineates the technical aspects of transorbital CCF embolization and demonstrates that this approach is a viable alternative to conventional transvenous methods for appropriately selected CCF cases. We supplement our case example and technical note with a literature review of this approach.

Endovascular targeted coil embolization using dual vessel approach for traumatic direct carotid- cavernous fistula following severe head trauma: technical notes
Direct carotid cavernous fistulas (dCCFs) represent different entitles from spontaneous cavernous sinus (CS) dural arteriovenous fistulas (CSAVFs). Traumatic dCCFs are direct arteriovenous communications between the internal carotid artery (ICA) and cavernous sinus, resulting from a traumatic tear of the horizontal or posterior ascending intracavernous segment of the ICA by skull fracture fragm...

We describe an unconventional endovascular approach to the treatment of traumatic carotid-cavernous fistulas. Four patients with large high-flow shunts have been successfully treated by trapping of the fistula by using a combination of proximal balloon occlusion and distal coil embolization. The latter was achieved following retrograde catheterization of the distal parent vessel via the contral...

BACKGROUND Carotid-cavernous fistulas are abnormal communications between carotid arteries or their branches and the cavernous system caused mostly by trauma. Posttraumatic fistulas represent 70% of all carotid-cavernous fistulas and they are mostly high-flow shunts (type A). This type gives characteristic eye symptoms. CASE REPORT This paper presents a 44-year old male patient with carotid-c...

Transarterial detachable coil embolization of direct carotid-cavernous fistula: immediate and long-term outcomes.
BACKGROUND Transarterial embolization is a standard method for management of direct carotid-cavernous fistula (DCCF). The purpose of this study was to report our experiences, and immediate and long-term outcomes of endovascular embolization of DCCFs by using detachable coils (DCs). METHODS Over 8 years, 24 patients with 25 DCCFs underwent endovascular DC embolization. There were 15 men and ni...
