Abstract :
Patients with ESRD ";End-stage renal disease"; require hemodialysis. The most desirable form of vascular access is the arterio-venous fistula (AVF). It is placed surgically joining an artery and a vein together. We propose an investigation protocol to understand the correlation between hemodynamics in this vessel and the associated clinical complications. Realistic 3D reconstruction of the fistula is the result of segmenting CT angiography images for two cases. Then the geometrical model is preprocessed by hybrid meshing and CFD results are confronted with medical image data such as calcifications.
