| Carotid
cavernous fistula is a shunting of blood from the carotid artery to
the cavernous sinus (a large vein, whose walls are composed of leavess
of dura, through which it runs). This may occur due to trauma,
or may occur spontaneously if an aneurysm of the carotid artery within
the cavernous sinus ruptures. This may present with pain in
the eye, pulsatile protrusion of the orbit, and double vision. |
