Effect of Wall Motion on Arterial Wall Shear Stress

Effect of Wall Stiffness on Arterial Wall Shear Stress during Pulse Wave Propagation

Effect of reverse flow on the pattern of wall shear stress near arterial branches.

Atherosclerotic lesions have a patchy distribution within arteries that suggests a controlling influence of haemodynamic stresses on their development. The distribution near aortic branches varies with age and species, perhaps reflecting differences in these stresses. Our previous work, which assumed steady flow, revealed a dependence of wall shear stress (WSS) patterns on Reynolds number and s...

A Nonparametric Method for Estimation of Arterial Wall Shear Stress

1 This paper combines two abstracts that were submitted for review to the 2004 Annual Meeting of the International Society for Magnetic Resonance In Medicine (Kyoto, Japan).

Mechanical aspects of blood-wall interaction : wall shear stress measurement

The predilection of atherosclerotic lesions for specific sites in the arterial tree is believed to be related t o the wall shear stress, exerted by the blood flow. Measurement of the magnitude of the wall shear stress is difficult and is frequently determined by an extrapolation of the velocity field t o find the wall shear rate and an estimation of the viscosity of the fluid in the neighborhoo...

Presentation of a Non-invasive Method of Estimating Arterial Stiffness by Modeling Blood Flow and Arterial Wall Based on the Determination of Elastic Module of Arterial Wall

Introduction: Arterial stiffness is an important predictor of cardiovascular risk. Several indices have been  introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. Since the  substitution  of  the  blood  pressure  changes  in  the  central  arteries  such  as  carotid  with  the  blood  pressure  changes in the brachial results in error in the blood...
