Wall shear stress (WSS), the circumferential wall tension (T) and the tensile stress (
The study was carried out in 16 patients with unilateral cerebral infarctions (UCI), 58 patients with risk factors (RF) for CVD and 25 healthy control subjects. The blood flow velocities (BFV), the diameters (D) and the vessel wall intima-media thickness (IMT) in the common carotid arteries (CCA) were recorded with color duplex sonography. Systolic (SBP) and diastolic (DBP) blood pressure were measured and mean blood pressure (MBP) was calculated by the formula of Wiggers. Whole blood viscosity (WBV) at the shear rate of 94.5 s-1 was measured on the day of the Doppler ultrasound examination with a rotational viscometer Contraves Low shear 30. Wall shear stress (WSS), the circumferential wall tension (T) and the tensile stress (

The axial velocity distribution and wall shear stress (WSS) distribution and contours are presented.
The structures of the flow around the bifurcation from CCA to the internal (ICA) and external carotid artery (ECA) are obtained considering characteristic time points for one pulse wave period. The axial velocity distribution and wall shear stress (WSS) distribution and contours are presented. The results manifest unsteady blood flow in the carotid bifurcation and dependence of the flow disturbances on the time and type of the stenoses. The recirculation zone behind the stenosis is the area of low WSS. Comparison of the peak WSS for the four different cases shows that it reaches the maximum value of about 6.7Pa at the characteristic point of T=0,2s for the cases with two and three stenoses.

The axial velocity distribution and wall shear stress distribution and contours are presented.
The numerical results of the blood flow in the CCA bifurcation give a detailed picture of the axial and radial velocity distribution and presented as velocity and vorticity magnitudes. The structures of the flow around the bifurcation from the CCA to the internal and external carotid arteries are obtained considering characteristic time points for one pulse wave period. The axial velocity distribution and wall shear stress distribution and contours are presented.

Also the brachial arterial blood pressure (BP) was measured and the hemodynamic variables in the common carotid artery (CCA): tensile stress (TS) and wall shear stress (WSS) were assessed.
Changes of the examined neurosonographic parameters: blood flow velocity (BFV), vessel diameters (Ds), vessel wall intima-media thickness (IMT) and stiffness, vasomotor reactivity (VMR) were found and they were correlated to the altered hemorheological variables: hematocrit (HT), fibrinogen (FIB), plasma (PV) and whole blood viscosity (WBV). Also the brachial arterial blood pressure (BP) was measured and the hemodynamic variables in the common carotid artery (CCA): tensile stress (TS) and wall shear stress (WSS) were assessed.
