Key result
Arterial geometry and flow parameters drive wall shear distribution variability in human aortic bifurcations.
Why the study?
Variability in shear rate distribution along human aortic bifurcations and its relation to arterial geometry and flow parameters was not well characterized.
Observational (n=10)
Wall shear varies widely with aortic geometry and flow; leaves open its standardization for atherosclerosis risk assessment.
Shear rates measured at sites along the walls of ten casts of human aortic bifurcations are presented to provide an indication of the variability in the shear rate distribution that can occur among individuals. The geometric characteristics and flow parameters for each of the casts are also given. Much of the variability in wall shear distribution seen here results from variations in arterial geometry; variations in flow parameters can widen further the normal range of shear distributions.

Mark et al. (1989) reported an observational. Variations in arterial geometry and flow parameters was evaluated on Shear rate distribution and variability. Variations in arterial geometry and flow parameters were found to drive much of the variability in wall shear distribution across ten casts of human aortic bifurcations.
