Carotid Cavernous Fistula Embolization
A carotid cavernous fistula can develop after trauma or spontaneously. Symptoms can include swelling and injury to nerves that control eye function. Imaging tests such as CT or MRI can provide clues to the diagnosis, but often a diagnostic catheter cerebral angiogram is necessary to confirm the diagnosis. Treatment options include endovascular therapy in which a small catheter is advanced into the blood vessels where the abnormal communication exists. Glue or a similar liquid embolic material is injected through the catheter and forms a plug at the abnormality to close the fistula.
