Cavernous Carotid Fistula
This is a specific kind of dural fistula that involves the carotid artery and a large vein behind the eye. It can result from trauma, a ruptured aneurysm in the carotid artery or an unidentifiable cause. Symptoms can include eye pain, swelling and redness, double vision or loss of vision if untreated.
Neuro-interventional treatment involves placing a catheter in the artery or vein and using material to block up the connection between the artery and vein. This material can include balloons, coils and glue.
