摘要

•First CFD-based flow analysis of proximal vasculature to arteriovenous fistula (AVF)•First use of ferumoxytol-enhanced magnetic resonance angiography (FeMRA) with CFD•FeMRA-CFD workflow generates accurate patient-specific haemodynamic profiles•2-3-fold wall shear stress (WSS) increase in proximal arteries following AVF creation•WSS in feeding artery juxta-anastomosis increased by a factor of 10 post-AVF
