Fig 4. A, Graph showing the values of wall shear stress (WSS) at 20 points along the aneurysm wall indicated in Fig 3A. Points 3–15 are located in the enlarging area. B, Graph showing the values of wall shear stress at 16 points along the aneurysm wall indicated in Fig 3B. Points 5–14 are located in the enlarging area. C, Graph showing the values of wall shear stress at 20 points along the aneurysm wall indicated in Fig 3C. Points 3–15 are located in the enlarging area. D, Graph showing the values of wall shear stress at 13 points along the aneurysm wall indicated in Fig 3C. Points 4–11 are located in the enlarging area. Min indicates minimal flow phase; acc, acceleration phase; max, maximal flow phase; dec, deceleration phase.
