The caroticocavernous fistula is a specific type of dural arteriovenous fistula characterized by abnormal arteriovenous shunting within the cavernous sinus. A caroticocavernous fistula results in high-pressure arterial blood entering the low-pressure venous cavernous sinus.
This interferes with normal venous drainage patterns and compromises blood flow within the cavernous sinus and the orbit. This is post RTA case with caroticocavernous fistula on the right side diagnosed on MR angiography.
