EFFECT OF RADIUS CHANGES OF MIDDLE CEREBRAL ARTERY (MCA) ON HEMODYNAMIC PARAMETERS

Abstract

: The article describes the study of the influence of the change in the morphometric features of the middle cerebral artery, i.e. inlet and outlet branch diameters on the values of hemodynamic parameters occurring on the arterial wall – wall shear stress (WSS) and pressure. For numerical calculations ANSYS CFX software was used. A parametric model of the vessel was developed, based on actual anthropometric MCA measurements of patients. Three optimizations were performed by changing individual radius of the arterial branches. The aim of the study was to verify Murray's law for the lowest stress and pressure values. The optimal bifurcation angle calculated in the previous simulations was used.
