“…From a previous model study, 19 it appeared that the angle of confluence has a strong effect on the flow in the junction and far downstream. Near the apex, a region with low velocities is present.…”

“…Consequently, the hemodynamic phenomena near the blood vessel wall vary between vessels, and this variation will affect the localization of atherosclerotic lesions. Striking examples of the large variations observed in human vertebrobasilar junctions are the variation of the confluence angle between 10°and 160°, 18,19 the local geometry of the apex of the vertebrobasilar junction, which varies from smooth and blunted to very sharp (Fig 1), and the difference between the diameter of the two vertebral arteries. 20,21 The influence of several geometric and hemodynamic parameters on the flow in vertebrobasilar junction models has been investigated by us in detail in earlier work.…”

“…For example, the angle at which capillaries join impacts microcirculation in the organs (Fujisawa et al 2006), and the convergent flow design was used to study the vertebro-basilar junction in the cerebrovascular circulation system. Ravensbergen et al (1996) found that the angle of confluence between the arteries significantly affected the formation of arterosclerotic plaques in the junction. Converging flows within tributary streams and river channels have serious impact on the local environment (Rhoads and Kenworthy 1995), albeit the Re are on the higher end of laminar flow regime (*1000).…”

“…The model has one inlet (aortic ostium) and six outlets (cross-sections of main arteries in the considered region). Owing to a significant differentiation in individual human anatomy (Daseler and Anson, 1959;Ravensbergen et al, 1996), which consists in a varied arrangement, length, kind of junctions, inner diameters and other geometrical parameters of the blood vessels under consideration, averaged data included in anatomical atlases, scientific publications, results of tomographic, magnetic resonance and ultrasonography imaging (Daseler and Anson, 1959;Bochenek and Reicher, 1974;Daniel, 1988;Michajlik and Ramotowski, 1996;Sinelnikov, 1989;Vajda, 1989) have been employed in the model. Models of vertebral arteries do not account for a part of secondary vessels branching off from the arteries under analysis before they join to form the basilar artery.…”
