Endovascular intervention to treat spontaneous carotid-cavernous fistula in a patient with Ehlers-Danlos Syndrome with an access site anatomical variant.

Vascular Ehlers-Danlos Syndrome (vEDS) is a rare and potentially life-threatening inherited connective tissue disorder. Patients with vEDS can present with spontaneous arterial dissections and ruptured aneurysms. There are previous reports of large artery dissections and vessel rupture following conventional catheter diagnostic angiography. We present the case of a patient with vEDS who had a spontaneous carotid-cavernous fistula (CCF) and visceral aneurysms, associated with a normal variant of corona mortis. A CCF was successfully treated with a transvenous approach with detachable coils.
