Hemodynamic analyses of the URPcomAA at the aneurysm status. A, Two-dimensional-DSA and 3D-DSA reconstruction images of the URPcomAA. B, Hemodynamic analyses in terms of WSS, pressure, velocity field, streamlines, and WSSG shows high WSS and low pressure at the distal aneurysm neck, and decreased WSS and elevated pressure at the aneurysm dome. C, Quantification along the longitudinal section of the aneurysm wall shows changes in the distribution of WSS and WSSG at the peak of the systolic period. WSS, wall shear stress; P, pressure VMP, von Mises pressure; VF, velocity field; SL, streamlines; WSSG, wall shear stress gradient.
