As per the guidelines issued by the Kidney disease outcome quality initiative, autologous arteriovenous fistula (AVF) is the most appropriate and best prescribed therapeutic strategy for hemodialysis procedure. Early detection of stenosed AVF increases the chances of a successful angioplasty by enhancing the patency rate for a longer period. This prospective observational study was conducted, with 87 evaluable hemodialysis patients, from September 2016 to January 2019. All patients were consented to perform endovascular intervention. The follow up was conducted at 1, 3, 6, 12 months. The mean patient age was 50.24 + 13.38.Hypertension (70.1%) and diabetes (28.7%) were noted comorbidities. About 78.1% of patients had brachiocephalic AVF, and 97.7% of lesions were stenotic juxta anastomotic. Also, 95.4% of patients had undergone hemodialysis through trans radial access. The primary and secondary patency rates at 12 months were 91.4% and 100%, respectively. Complications, including hematoma and surgical thrombectomy were noticed in 4.6% of patients. Balloon angioplasty procedure, either transradial or transbrachial, proved to be effective in all dysfunctioning AVF patients with > 30% stenosis. This can salvage the impending failure of AVF in hemodialysis patients with high primary and secondary patency rates over a year's time.
