J0203-1-5 3D visualization of numerical simulation of blood flow on intracranial stent

Abstract

The effect of stent on the flow reduction in cerebral aneurysm has been reported in CFD studies showing the stent position or the strut shape may affect the flow reduction. The 3D visualization may help easily to specify the inlet zone from parent artery to aneurysm and to find the relationship between the effective strut position and the flow pattern. Then we simulated adding a strut to a stent model on the inlet zone after specifying the zone using 3D visualization system. After moving the strut and repeating the visualization of results, we found a strut on the zone may reduce the flow into aneurysm effectively. The results may suggest the 3D visualization is useful for the assessment of strut position with effective reduction of flow into aneurysm.
