Contour plots of the WSS values averaged over a cardiac cycle for the sequential MRI scans at (A) 4, (B) 5, and (C) 7 months (mos) after fistula creation. Although the highest WSS values were found at the anastomosis (arrow) and the stenotic region (arrowhead) of the fistula vein at all 3 time points, AVF WSS decreased from 4 to 7 mos in this patient. Note that the color scale bar was adjusted for peak WSS observed at each time point to graphically illustrate differences in WSS values along the vein. Also note that the anastomosis and artery were maintained at the same angle of view in each reconstruction, but the fistula vein contorted over time so that the view of the accessory vein became more obscured at 7 months.
