The case refers to a middle-aged man who presented with a complete cavernous sinus
syndrome and was found to have a ruptured cavernous carotid artery aneurysm. This
could not be addressed with endovascular means after two attempts. He was treated
with an EC-IC bypass with a radial interposition graft, trapping of the aneurysm with
preservation of the ophthalmic artery and suction decompression of the aneurysm.
