Large Eddy Simulation unveils ischemic attack in Moyamoya patients

Researchers from Tohoku University have unveiled the causes of transient ischemic attacks (TIAs) in early-stage Moyamoya patients using Large Eddy Simulation. The study, published in Nature’s Scientific Reports showed that complex hemodynamic interactions, driven by momentum-viscous interactions with blood’s non-Newtonian viscosity, cause multiple mechanisms that lead to cerebral blood insufficiency. Loss of phase-shift, Rankine vortex and local elevated viscosity structures impedes blood flow in diseased arteries.
