Objective: This is a review of Arteriovenous Fistulas (AVF) created for hemodialysis in South Eastern Railway Hospital, Garden Reach, Kolkata from August 2017 to September 2020 in an attempt to decide success factors for improving success in AV fistulas for future endeavours. Design: A total of 181 AVFs were created in 183 patients. Mean follow-up duration was for 2 years. Retrospective observational study of 183 cases of AVFs was done. Materials and Methods: Categorical variables were compared using Pearson’s chi square test for independence of attributes or fisher's exact test as and when appropriate. Continuous variables have been expressed as mean, median and standard deviation and have been compared across the groups using unpaired t test. Multivariate analysis done using multivariate logistic regression. If any p value is less than 0.05 it has been considered as significant. Results: There were 158 (87.3%) successful cases and 23 (12.7%) failures. Attempt was abandoned in 2 patients. Basilic vein was used in 15 (8.3%) cases, cephalic vein in 163 (90.1%), and antecubital vein in 3 (1.7%) cases. End of the vein was anastomosed to side of the artery in all the cases. We got bruit in 160 (88.4%) and thrill in 149 (82.3%) cases. During dialysis, flow rate >300 ml/min was obtained in 158 (87.3%) cases. Conclusion: The presence of bruit and thrill after surgery increase chances of successful AVF.
