COMPARATIVE STUDY OF END TO SIDE VERSUS SIDE TO SIDE ARTERIOVENOUS FISTULA: A TERTIARY CARE CENTER EXPERIENCE

Abstract

Background: Arteriovenous Fistula creation is one of the commonly performed procedure among Plastic surgeons. There is always an argument regarding various techniques of the fistula with lack of conclusive evidences in the past literature to recommend any of the anastomosis type. With this study we aimed to compare the two different common techniques of fistula - end to side (ES) and side to side (SS).

Material and Methods: Total 80 patients were included for the retrospective analysis from January 2018 to January 2020 who were divided into two groups as ES (proximal end of the transected vein to the side of the artery anastomosis) and SS (side of the artery to the side of the vein anastomosis) groups. Each group was containing 40 patients. Follow up was done at 3 and 6 months.

Results: Statistical analysis of demographic, preoperative, complications and follow-up data did not show any statistically significant difference. However, post operative complications like venous hypertension and steal syndrome were found only in SS group.

Conclusion: With our study we can conclude that after comparing for a follow up period of 6 months we found statistically no significant difference between the two techniques. However, possibility of better insight in regard of patency rate, complications and other parameters after a longer duration of follow up could not be ruled out.
