It is essential both due to its morbidity and mortality, and impact on quality of life. Percutaneous endovascular interventions have been widely used and tested for the management of dysfunctional dialysis access and as an effective alternative compared to similar surgical interventions.Objectives: To provide information on stenotic complications of both native and prosthetic venous artery fistula, indication of fistulography, and endovascular treatment.Methods: Multicenter observational retrospective study including 59 patients with end-stage chronic kidney disease stage V on hemodialysis who underwent fistulography due to suspected stenotic complications of arteriovenous fistula during renal replacement treatment from January 2016 through October 2022. Demographic data, comorbidities, treatments, and postoperative results were collected from each patient.Conclusions: The advent of new endovascular techniques provides safe, simple, and effective tools for the diagnosis and treatment of arteriovenous fistulas achieving greater durability in their permeability.
