Figure 6: (Case 1) Lt IC-PC aneurysm in a 63-year-old woman with subarachnoid hemorrhage. (a) Cranial CT shows diffuse subarachnoid hemorrhage. 3D-CTA (b) shows the aneurysm (arrow). (c) Enlarged stereo surgical view is shown (upper: a set of stereo images for the cross-eye method, lower: a stereo color anaglyph). The stereo image shows vital structures (anterior choroidal artery, arrow head; posterior communicating artery, white arrow head) around the aneurysm (arrow). (d, e) Stereoscopic simulation images for every step of the left pterional approach
