Comments on the mathematical modelling of a vertebrobasilar stenosis
Journal Title: INCAS BULLETIN - Year 2016, Vol 8, Issue 3
Abstract
In the present paper the case of a stenosis on the basilar artery is investigated. To analyze the problem CT angiography and MRI angiography were performed. To model this real case a non-Newtonian mathematical model was taken into account for the blood flow, while the vessel walls of the arteries and the arterioles were considered to have viscoelastic and elastic behavior, respectively – as we presented already in previous papers [1], [2]. Using COMSOL Multiphysics 3.3 we performed some numerical simulations to obtain some results with regard to blood velocity, blood pressure and streamlines.
