Design outcomes

Primary

Measure	Time frame
We will provide a descriptive evaluation of blood flow patterns and derived parameters in our hemodynamic models, which is common practice in studies on computational fluid dynamics simulations in vascular access. The secondary study parameters are the degree of stenosis at which the graft is at risk of thrombosis according to the computational fluid dynamics model, and the associations between hemodynamic parameters and future stenosis development.	—
