Geometry & hemodynamics of arterial stenosis: A clinical and computational study

Abstract

Stenoss is abnormal narrowing of blood vessels. The presence of stenosis in arteries may cause critical flow conditions depending upon their severity, and occurence which may lead to stroke and heart-attack. A clinical study is done on more than 130 patients along with 2D axisymmetric model of the carotid artery for computational study with same shapes for the same degrees of constrictions. The incompressible Navier-Stokes equation has been considered as the governing equation of the fluid flow and it has been solved with varying flow parameters using standard software package COMSOL. The radial velocity profiles at various points of the flow field, the centerline velocity plot and the centerline pressure plots have been obtained for clinical validation.
