Eligibility
Inclusion criteria
Inclusion criteria: 1. Aged >18 years old 2. Life expectancy >1 year 3. Clinically mature dialysis fistula (AVG or AVF) already used for hemodialysis with adequate pump speed and dialysis efficacy for at least 4 consecutive sessions with the two-needle technique 4. Signs of fistula dysfunction (absent thrill, low flow, high venous pressure, high pulsatility, needling problems, abnormal pulsatility, abnormal auscultation, extremity edema, etc) 5. Hemodynamically significant (>50%) stenosis in juxta-anastomotic or outflow vein of AVF (excluding central veins defined as veins medial to the lateral margin of the first rib) or in the venous anastomosis, juxta-anastomotic segment or outflow vein in AVG (excluding central veins).
