The Wall Shear Stress Contours distributions of the aneurysm at the systolic peak (t = 0.2 s). Pre-operatively, the local WSS on the remnant neck was greater than that in other regions of the aneurysm. In the immediate post-operative period, the local WSS on the remnant neck decreased. In the first follow-up, compared to the immediate post-operative period, high local WSS at the remnant neck of recanalized case was observed. In the second follow-up, high local WSS at remnant neck of the recanalized case was also can be found. For the panel inside the image of Fig. 6, the red region on the top responds to high wall shear stress, while the blue region at the bottom responds to low wall shear stress
