Hemodynamic analysis of virtual stent design for atherosclerotic carotid artery

摘要

We propose a technique to reverse engineer a normal carotid bifurcation from an abnormal artery model based on B-Spline interpolation. This enables us to assess the blood flow pattern in a patient-specific artery for the stenosed and virtually stented conditions. This technique may be applied to understand the cardiovascular condition and to develop a stent to eliminate stenosis and flow resistance. Furthermore, we hypothesise that velocity, wall shear stress and pressure gradient are the key hemodynamics parameters for determining stent performance in terms of improved cardiovascular flow. We show that stenting are able to improve the diseased artery condition from the hemodynamics perspective.
