Figures
- Fig 1.
Computer simulation before stent placement in a superior cerebellar artery aneurysm (same patient as in Fig 2). A, 3D image after automated aneurysm detection (blue) and stent simulation. B, Corresponding graph indicating vessel diameters in segment lengths. Proximal and distal diameters are indicated by D1 (4.2 mm) and D2 (2.5 mm). The aneurysm neck is indicated by the bidirectional arrow. Use of a 37-mm stent will provide a proximal and distal overlap of 10 mm.
- Fig 2.
A 58-year-old woman with a ruptured superior cerebellar artery aneurysm without a neck. A and B, 2D and 3D vertebral angiograms demonstrate the dysplastic distal basilar segment with a large superior cerebellar artery aneurysm. The superior cerebellar artery arises from base of the aneurysmal sack, and the dysplastic segment extends to the proximal posterior cerebral arteries. C, Result after stent-assisted coiling. Proximal and distal stent markers are indicated by arrows. Flow in the superior cerebellar artery is preserved.
- Fig 3.
A 46-year-old woman with a wide-neck posterior inferior cerebellar artery aneurysm, additional to another ruptured aneurysm. A, 3D angiogram demonstrates the posterior inferior cerebellar artery originating from the base of the aneurysm. B, 3D image after automated aneurysm detection and stent simulation. C, Complete occlusion after stent-assisted coiling with preserved flow in the posterior inferior cerebellar artery.
