The aim of our study was to determine the preoperative factors predicting the outcome of arteriovenous fistulas (AVF) in chronic kidney disease (CKD) patients.

Methods: A single-center prospective observational research was conducted on CKD patients necessitating vascular access surgery. Informed consent was taken from the patients. Factors such as patient’s demographics, flow across vein, and anastomosis were

Recorded during the data collection. The patient’s vessel status recorded preoperatively by a Doppler ultrasound. The data was evaluated to determine the risk variables that influence AVF outcomes.

Results: Evaluation of 35 patients of BC AVF was included in the study. The study results demonstrated that the Mean age of the patients was 51± 10.2.

Male predominance (60%) was observed during the study.  Influence of artery and vein diameter and flow rate across anastomosis and flow rate across vein on success rate were determined and evaluated for the factors predicting their outcome.

Conclusion: The output vein diameter, artery diameter, and flow rate in the vein and across the anastomosis were shown to be the most important factors in the success of the proximal and distal arm fistulas in this investigation. These findings might aid in the identification of a vulnerable group that would benefit from closer monitoring and perhaps early intervention in order to ensure AVF maturity or the establishment of an AVG as main access.
