Introduction: Failing AVF can be salvaged by open surgical technique, percutaneous encdovascular or hybrid methods. In this study our institutional experience on balloon fistuloplasty is described. The objective is To investigate the effectiveness of endovascular balloon angioplasty to preserve the patency of failing hemodialysis arteriovenous fistulas (AVF). Materials And Method: 1. Period Of Study - 3 YEARS AUG 2019 TO AUG 2022 2. Total No Of Patients – 20 3. Study method – retrospective observational study Results: In a total of 20 patients 16 cases (80%) were successful with immediate restoration of optimal flow rate during dialysis.At the end of 6 months – 8 were successful. 5 had failed fistuloplasty, 3 – expired. Conclusion:Fistuloplasty is a minimally invasive percutaneous procedure with established safety and efficacy to restore the normal function of AVF.Most common site is Cephalic V puncture sites. It is advised to follow Rope Ladder technique to avoid AVF failure.
