====== Indirect carotid cavernous fistula ======


Indirect [[carotid cavernous fistula]] occur when small dural branches of the external and internal carotid arteries (ICA) drain into the [[cavernous sinus]].

Indirect fistulae are low-flow fistulae and the equivalent of a dural arteriovenous fistula of the cavernous sinus and comprise the majority of CCFs encountered in clinical practice.
