Streamlines of the aneurysm at the systolic peak (t = 0.2 s). Pre-operatively, the blood flow entered the aneurysm sac and formed a large and complex vortex inside aneurysm. In the immediate post-operative period, some minor blood flow entered into the aneurysm). In the two follow-ups, some slight blood flow still entered into in the aneurysm, while high velocity and dense streamlines could be observed at the remnant neck of the recanalized case. For the panel inside the image of Fig. 5 ,the red region on the top responds to high velocity, while the blue region at the bottom responds to low velocity
