Comparative Study of Efficacy of End-to-Side with Side-to-Side Arteriovenous Fistula in patients on Hemodialysis

Aim: To compare efficacy of end-to-side with side-to-side arteriovenous fistula in patients on hemodialysis. Methods: Randomized controlled trial conducted in the Department of Urology, Nishtar Hospital Multan for a period of 6 months. The exact dates are from 08-7-2012 to 08-1-2013,. Sample size was 168 patients in each group. Sampling technique was non-probability purpose sampling Results: Among 336 patients divided in two equal groups of 168 patients each. Mean age (+/- S.E.M.)of patients was 39.79 +/- 0.41 vs. 39.45 +/- 0.51 in group A and group B respectively. There were 15(8.9%) vs. 18(10.7%) patients having hemorrhage at 24 hours in group A and group B respectively. There were 3(1.8%) vs. 7(4.2%) patients having hemorrhage assessed after 1 month in group A and group B respectively. Efficacy of group A (end to side technique) was 89.3% while in group B (side to side technique) efficacy was 85.1%. There was no significant difference regarding efficacy between the groups i.e. group A (end to side) or Group B (side to side) p=0.253. Conclusion: Efficacy of end-to-side AV fistula is superior to side-to-side AV fistula in terms of postoperative hemorrhage at 24 hour and one month post operatively. There was no significant difference regarding efficacy between the groups i.e. group A (end to side) or Group B (side to side) p=0.253.
