Figures
- Fig 1.
A, Computer model of the reconstructed aneurysm with in vivo aneurysm dimensions. B, Three-fold enlarged transparent silicone model of the reconstructed aneurysm.
- Fig 2.
A, Photo of the model with a 10% coil-packing attenuation. B, Photo of the model with a 15% coil-packing attenuation. The coil winding that seems to protrude into the parent vessel is located completely in the aneurysm lumen.
- Fig 3.
Steady-flow field in the aneurysm visualized by path lines separated into 3 colors representing the 3 visualized streams. A and B, Two images show the formation of the aneurysmal flow structure. B and C, Two views are shown for a better 3D representation of the complex flow field.
- Fig 4.
A, Flow visualization of the WSS surface vector field with stream lines (white) and critical points (yellow, saddle; blue, repelling or attracting node; red, source or sink stagnation point). B, Experimental flow visualization of surface path lines in the respective model by using the Wall-PIV technique. Arrows show flow directions.
- Fig 5.
Max-min images of path lines assessed over the 25-second period in the ACA aneurysm model without coils (A) and with coils of different volume-packing attenuations of 10% (B), 15% (C), and 20% (D). Arrows show local flow directions.
- Fig 6.
Six different flow fields (2 left columns) show near-wall flow variability in the near-wall fluid layer (<150 μm) generated by different coil structures with a 15% coil-packing attenuation. Arrows show flow directions. In the right column, the overlays of the 2 max-min images from the same row are shown.
- Fig 7.
Two overlapped max-min images for comparing results of the Wall-PIV visualization under steady and pulsatile flow conditions in the aneurysm without coils. Red-colored path lines represent results for steady flow conditions.
