Abstract: Introduction: Indication for constructing an arteriovenous fistula (AVF) as a vascular access for hemodialysis is deteriorating renal function in patients with chronic kidney disease who will ultimately require maintenance hemodialysis as a modality of renal replacement therapy. Color Doppler ultrasound is commonly used for preoperative vascular mapping and postoperative evaluation of AVF. Methods: Dialysis-dependent patients aged 20 to 83 years undergoing primary Radiocephalic arteriovenous fistula (RC-AVF) creation from 1st September 2021 to 30th March 2023 were included in our prospective observational cross�sectional study. After obtaining consent all the patients underwent preoperative vascular mapping and postoperative follow up evaluation at 6 weeks with Color Doppler ultrasound (CDUS). Result: Successful maturation of AVF was seen in 60 (75%) patients and failure was seen in 20 (25%) patients. A greater radial artery diameter (RAD) and cephalic vein diameter (CVD) was significantly associated to higher rates of successful AVF maturation (P<0.001). There was no significant association between the mean age of a patient (P=0.344) and gender of the patient (P=0.588) with outcome of fistula maturation. Overall, most common cause of early AVF failure was outflow vein occlusion (thrombosis) seen in 12 (15 %) of patients followed by Failure to mature (FTM) seen in 8 (10%) patients. Conclusion: This study suggests a statistically significant correlation between the diameter of cephalic vein and the diameter of radial artery with the outcome of fistula.
