Dural AV Fistula, Carotico Cavernous Fistula

Dural AV Fistula (DAVF) and Carotico-Cavernous Fistula (CCF) are two types of abnormal connections between arteries and veins in the brain, involving the dura (outer brain covering) and the cavernous sinus, respectively. Both can lead to serious complications like increased pressure in the veins, brain hemorrhage, or neurological deficits.
