Steady Vortices in Arterial Flows.

Many authors describe the movement in veins and arteries applying the Poisseuille flow pattern according to which all streamlines are parallel to the walls of vessels, and the blood flow rate is proportional to the pressure drop. The presence of vortices may imply two-dimensional stress state in the wall of the vessel. It may be suggest that the additional stress may increase the probability to injure the cells of endothelium. The progressive development of atheroma sedimentation in the vicinity of bifurcations of arteries confirms the hypothesis mentioned above.
