A, Lateral view, angiogram of the right internal carotid artery following initial debridement and packing of the sphenoid sinus shows fusiform dilation of the cavernous portion of the vessel. Occlusion of the carotid artery resulted from packing of the sphenoid sinus at the time of surgery.
B, Injection of the left internal carotid artery shows good filling across the anterior communicating artery. The visualized portions of the supraclinoid right internal carotid artery (arrows) and the right middle cerebral artery are of normal caliber.
C, Postembolization plain film shows microcoils within the lumen of the aneurysm and proximal detachable balloons occluding the right internal carotid artery
