WSS and blood flow velocity measurement in the RPcomAA and URPcomAA at the aneurysm and pre-aneurysm status. A, How to choose sections of the neck, body, and dome of an aneurysm (schematic). Hemodynamic data analyses show that the aneurysm neck is subject to elevated WSS and blood-flow velocity, whereas the dome is subjected to the lowest WSS and blood-flow velocity. B, How to choose sections at the area of aneurysm formation and adjacent parent artery (schematic). Hemodynamic data analyses show that the area of aneurysm formation is subject to extremely high WSS and blood-flow velocity compared with the adjacent parent artery.
