FIG 3.

Representative contrast-filling case. A 73-year-old woman with an asymptomatic aneurysm. A, Digital subtraction angiography shows a large wide-neck aneurysm located at the left paraclinoid portion of internal carotid artery (left), which does not disappear at 6 months after the FD treatment (right). B, Streamline of FV in the FD model. The mean FV at the dome is 0.22 m/s. C, Contour line of wall shear stress in the FD model (mean value in the dome is 1.25 Pa). D, Contour line of the shear rate in the FD model (mean value in the dome is 12.8 × 10² 1/s). E, Intra-aneurysmal nRFV of 0.96 with an average flow velocity of >8 cm/s.
