Abstract
All patients were examined post-operative AVF either for maturity or presence of complications. Assessment with arterial diameter, fistula diameter, velocity at the fistula, 2cm proximal, Volume flow rate were measured at anastomosis site and during hemodialysis for shunt complication. Doppler indices (PSV, EDV and RI) were measured at the site of anastomosis, draining veins and afferent arteries. Volume of blood flow was also measured at the site of anastomosis. CDUS is a noninvasive technique that allows the assessment of both anatomy and hemodynamics of an AVF. This technique is free of any known risk, cheap and can be used at the bedside. CDUS outlines the AVF lumen and allows definition of lumen dimensions and detection of luminal encroachment
