[Direct carotid-cavernous fistula. Clinical, radiologic and therapeutic studies. Apropos of 49 cases].

Abstract

Direct carotido-cavernous fistulae due to rupture of an aneurysm or trauma are uncommon. When flow through the breach is minimal, vascular treatment may not be necessary unless clinical signs appear since this type of fistula heals spontaneously. In other cases, an endovascular balloon procedure is indicated. There are few complications. Embolization with coils or other devices should only be used in selected cases when the breach is too small for the balloon.
