More robust prospective studies are needed to validate our findings and to identify prognostic factors associated with long-term AVF patency after endovascular salvage. Additionally, it is critical to develop surveillance protocols focused on fistula research and care, as well as the development of institutional guidelines.enMedicineHemodialysisSurgeryArteriovenous fistulaComorbidityFistulaThrombosisDialysisReferralMedical recordarticle
