Giant Aneurysm of the Cervical Internal Carotid Artery Treated by Proximal Coil Embolization under Temporary Balloon Occlusion.

We report a patient with a giant aneurysm on the left cervical internal carotid artery (ICA) treated successfully by proximal coil occlusion. Fibered platinum coils were delivered via a 5-F catheter under temporary balloon occlusion of the proximal ICA and without complications. MR imaging ten months after the procedure showed the aneurysm to be reduced in size and sub totally thrombosed. Retrograde partial filling of the aneurysmal lumen was present, however. We describe the case in detail and discuss the ideal treatment of the cervical ICA aneurysm.
