Wall shear stress in stenotic artery

The effects induced by a mild arterial stenosis on the wall shear stress is theoretically investigated. Distribution of shear stress along canine femoral artery and during the cardiac cycle is calculated simulating both the physiological state of the artery and the stenotic condition. The presence of a stenosis in the vessel significantly influences the shape of shear stress distribution. Shear stress in the stenotic case approximately increases of 30% both for the mean and the peak values.
