Theoretical impact of the considered variables on the iliac arteries

Variables	Theoretical impact on the vessel
Static pressure	Associated with the proliferation of vascular smooth muscle cells
Dynamic pressure	Associated with a variation of the blood flow velocity, which has been linked to a higher risk of re-stenosis
Reynolds number (Re)	High Re number indicates a disturbed blood flow and is associated with a hemodynamic turbulence, which causes endothelial dysfunction and thrombogenicity.
Vorticity magnitude	High in the presence of a severe stenosis. A high vorticity magnitude, especially in a bifurcation lesion, affects both the blood flow velocity and vorticity, promoting endothelial dysfunction and/or thrombogenicity.
Stream function	Related to a change of the characteristic non-Newtonian fluid motion
Strain rate	Low levels have been related to an in-stent restenosis
Wall-shea>	High Wall-shear stress plays a major role in both generation, progression and destabilisation of atherosclerotic plaques
