چکیده
Introduction: The measurement of Arterio-Venous (A-V) Fistula Recirculation has important diagnostic implications because the efficiency of haemodialysis (HD) may be limited, resulting in dialysis delivery being less than that prescribed. The purpose of the study is to determine its prevalence and causes in our HD patients. Results: Blood flow rate and dialysate flow rate were 300 mL/min and 500 mL/min respectively. The prevalence of A-V fistula recirculation was 17% (17patients).Average degree of recirculation between these patients was 9.562.32 %. The most common cause was misplacement and or misdirection of needles (17 patients). The second cause was heart failure with Ejection Fraction > 40% (8 patients). No difference was seen between diabetic versus non diabetic (P =0.28) and hypertensive versus normotensive (P =0.21%) HD patients. Conclusions: A-V fistula recirculation is common occurrence in HD patients and the most common cause of recirculation is misplacement and or misdirection of needles so we should have more emphasis on education and training of HD staffs.
