Numerical simulation of blood flow in a blood vessel with an aneurysm
by Constantin Nichita, Department of Mathematics, SUNY at Buffalo.
An aneurysm is a dilation of the artery, which may rupture and cause a hemorrhagic stroke. Stenting is a minimally invasive method of treatment. By placing a stent across the aneurysmal neck, blood flow into the aneurysm is reduced and the intraaneurysmal vortex is diminished.
The immersed boundary method (developed by Charles Peskin) was employed to model the blood-stent-artery interaction.
The movie shows velocity profiles for pulsatile blood flow with a frequency of one beat per second in a stented and non-stented model artery.
