Low wall shear stress is known to cause atherosclerosis in the arterial wall. Hemodynamic patterns of the iliac arteries were assessed in two groups (i.e. dilated and undilated abdominal aorta) in terms of the patterns of streamlines and mean values of wall shear stress (WSS). As a result, abnormal flow dynamics such as vortex and/or turbulent flow occur in the abdominal aortic aneurysm (AAA) also affected the hemodynamics in the downstream iliac arteries, which reduced their WSSs.
