Hemodynamic analyses of the RPcomAA and URPcomAA at the pre-aneurysm status. A, Hemodynamic analyses in the RPcomAA and URPcomAA at the pre-aneurysm status in terms of WSS, pressure, velocity field, streamlines, and WSSG. A, C, elevated WSS, low pressure, high blood-flow velocity, and obvious changes in WSSG are observed at the site of aneurysm formation of the parent artery in the RPcomAA and URPcomAA models; B, D, Quantification along the longitudinal section of the area of aneurysm formation shows changes in the distribution of WSS and WSSG at the peak of the systolic period in both models. WSS, wall shear stress; P, pressure VMP, von Mises pressure; VF, velocity field; SL, streamlines; WSSG, wall shear stress gradient.
