Figure 4.
Ultrasound measurements in the aorta proximal to the fistula. Ultrasound derived measurements in the suprarenal (left column) and infrarenal (right column) aorta; diameter (A,B), velocity (C,D), and calculated SS (E,F). In all graphs, n = 7 for shams and 5 for the fistulae groups. ANOVA results: A, P = 0.09; B, P = 0.03; C, P = 0.035 (PSV) and P = 0.25 (EDV); D, P < 0.0001 (PSV) and P < 0.0001 (EDV); E, P = 0.0235; F, P < 0.0001. For all figures, *denotes P < 0.05 compared to sham group, post hoc test. PSV, peak systolic velocity; EDV, end-diastolic velocity.
