Abstract

Background: Arterio-venous fistula is the preferred type of vascular access in patients requiring hemodialysis. (1-3) They have longer patency with low complication rates as compared to grafts. Still arteriovenous fistulas surgery can give rise to various complications
Objectives: this study was done to evaluate the various complications, early as well as late, arising from the arteriovenous fistula surgery.
Materials and Methods: This study was conducted over a span of 3 years from October 2019 to October 2022 comprising of 284 patients of chronic kidney disease who were on regular hemodialysis underwent surgery to create end to side radio-cephalic arteriovenous fistula formation for vascular access.
Results: out of 284 patients 22(7.74%) patients required reoperation. Thrombosis with failure of AV fistula requiring reoperation was seen in 19(6.69%) patients. Reoperation for bleeding, Aneurysm and ischemic steal syndrome was seen in 1 patient each.
Conclusion: Thrombosis with loss of AV fistula is the most common complication requiring reoperation after Radio-cephalic arteriovenous fistula surgery for vascular access in patients on hemodialysis.
