Background: Suitable vascular access is an important prerequisite for uncomplicated hemodialysis. The purpose of this study was to comparison the efficacy and complications of end-side anastomosis of brachial artery to cubital perforating vein versus side-side brachiocephalic arteriovenous fistula formation in hemodialysis candidates.Methods: In a clinical trial study, 85 patients undergoing arterial venous fistula placement were randomly divided in two groups of 42 and 43 patients. The first group was fed into the cephalic vein fistula to the adjacent brachial artery by side to side method, and in the second group, the cephalic vein fistula was transferred to the brachial artery by end to side method. The efficiency and duration of catheter operation were compared between the two groups.Findings: The mean duration of function of the fistula was 36.66 ± 2.34 weeks. The mean duration of fistula function in the two groups of side to side and end to side was 21.68 ± 2.03 and 38.4 ± 3.8 weeks, respectively, and there was no significant difference between the two groups according to the log-rank test (P = 0.41).Conclusion: The type of anastomosis in patients undergoing arteriovenous fistula does not have an effect on the efficacy and survival of fistula. However, since the lateral anastomosis has a greater flux of blood flow and less pressure in the vascular wall, this method seems to be preferred to anastomosis to the side shaft. At the same time, more studies are recommended.
