摘要：

Shunt murmurs are believed to be generated when turbulent flow, which is generated as a large amount of blood passes quickly through the anastomosis site of the VA, causes the vascular wall to vibrate. In this report, the pseudo shunt murmurs generated in the AVF models with different diameter stenosis rates was measured, and the flow in these models were visualized using particle image velocimetry (PIV). As a result, in the several model with a low diameter stenosis rate, the flows were laminar, and the frequency component of the pseudo shunt murmurs were mainly composed of low frequency components. As a result, it was considered that the change in the flow in the blood vessels by stenosis may have an effect on the acoustic characteristics of the shunt murmurs. © 2020, Japan Soc. of Med.
