The aim of this study was to investigate the repartition of the flow between an artery and its graft for several values of the geometric and dynamic parameters (length and severity of the stenosis, Reynolds number and frequency pulse value). The model, fabricated in silicone, was included in an hydrodynamic test bench, allowing to reproduce physiological conditions. Our study showed that the severity of the stenosis was the most influent parameter on the repartition of the flow; in particular, a 75% severity was necessary to obtain a repartition 70-30% between the graft and the artery.
本研究的目的是针对几何和动力学参数（狭窄的长度和严重程度、雷诺数和脉搏频率值）的多个取值，研究动脉与其移植物之间血流的分配情况。该模型由硅胶制成，被置于流体动力学试验台上，以重现生理条件。我们的研究表明，狭窄的严重程度是血流分配的最主要影响参数；特别是，要在移植物和动脉之间实现70-30%的血流分配，狭窄严重程度需达到75%。
