The treatment of indirect carotid cavernous fistulas (CCFs) is challenging and primarily accomplished by endovascular means utilizing a variety of embolic agents. Transvenous access to the cavernous sinus is the preferred method of embolizaiton of indirect CCFs as they are frequently associated with numerous small-caliber meningeal branches. Although the inferior petrosal sinus is the simplest, shortest, and most commonly used venous route to the cavernous sinus, the superior ophthalmic vein, superior petrosal sinus, basilar plexus, and pterygoid plexus present other endovenous options. Occasionally, however, use of these venous routes may not be possible due to vessel tortuosity or sinus thrombosis and occlusion. The authors report a case of an indirect CCF that could not be treated endovascularly due to inability to access the cavernous sinus via a transfemoral transvenous approach. Angiography revealed a small, deeply located superior ophthalmic vein that was thought to be suboptimal for a direct cutdown. The cavernous sinus was cannulated directly via a transorbital approach using fluoroscopic guidance with a 3D skull reconstruction overlay. The fistula was subsequently obliterated using ethylene vinyl alcohol copolymer (Onyx). The technique and advantages of both 3D osseous reconstruction as well as Onyx embolization are discussed.

The formation of a traumatic arteriovenous fistula (AVF) between the extracranial middle meningeal artery (MMA) and the pterygoid plexus (PP) is very rare, and understanding of this condition is limited. This paper reports the case of an 8-year-old who suffered minor injuries after a high fall four months prior to admission and showed good recovery after one month. However, the child gradually developed exophthalmos of the left eye and conjunctival redness one month prior to admission. Auscultation revealed an intracranial murmur near the left side of the face, in the temporal region. A digital subtraction angiography (DSA) showed rupture of the left extracranial MMA and an AVF between the MMA and the PP. The blood drained toward the cavernous sinus, resulting in retrograde blood flow into the ophthalmic vein and the cortical vein. The diagnosis was an AVF between the MMA and the PP, and a combination of coils and Onyx liquid embolic agent was employed to perform AVF embolization. Follow-up six months later indicated no recurrence of the AVF, and the patient showed good recovery with a normal-appearing left eye. The AVF in this case drained toward the cavernous sinus, and symptoms of increased intracranial venous system pressure were apparent, similar to those produced by fistulas between the internal carotid artery and the cavernous sinus. This condition is very rare, and the use of coils in combination with Onyx for AVF embolization is novel, warranting the reporting of the current case.
