N2 - Usefulness of endoscopic imaging of cerebral aneurysms is presented. 3-D luminal images were obtained using a new processing technique which extracts CT numbers in the boundary region between the vessel wall and contrast media filled in the vascular lumen. Clinical application of this technique to complicated large cerebral aneurysms showed that, with this 3-D CT endoscopic imaging, anatomical details of cerebral aneurysms such as the orifice of the aneurysm, intraluminal thrombus, and calcification of the wall could be clearly demonstrated. Using a 3-D imaging method by Helical CT, virtual views of various surgical approaches were compared preoperatively. With this technique, not only virtual surgical views of aneurysms and related vasculature, but also surgical views after virtual resection of skull base bone to a desirable extent are freely available. We operated on two large, complicated aneurysms and one broad-based aneurysm after obtaining 3-D CT endoscopic images of the aneurysms. Such information was found to be very useful for determining difficult and complicated cerebral aneurysms and broad-based aneurysms for coil embolization or direct open surgery.
