Lateral-projection angiogram of the left common carotid artery shows a direct carotid cavernous fistula, with the ostium in the inferior C4 portion of the ICA just anterior to the posterior genu. Fistulous flow to the cavernous sinus, with effluence to an attenuated superior ophthalmic vein, a single channel connecting to the pterygoid plexus, is present. No inferior petrosal sinus opacified.

Venous-phase angiogram shows the pterygoid plexus, maxillary veins, facial vein, and retromandibular-external jugular vein channels.

Rapid Transit microcatheter has been passed into the cavernous sinus via the pterygoid plexus. Injection of contrast medium shows the venous compartment.

Injection of the left common carotid artery after placement of standard and fibered GDC shows complete occlusion of the fistulous flow.
