Brief Summary
Arteriovenous fistulas (AVFs) for hemodialysis often fail to become usable due to failure to mature (FTM). The most common cause is narrowing of the artery or vein (stenosis). Another potential cause is the presence of collateral or side branch veins that steal blood flow from the main fistula channel. Some believe that occluding these veins might help maturation of those failing AVFs. To evaluate if this actually works, patients with FTM will be randomly assigned to side branch vein ligation (or not), and rates of AVF maturation of the two groups will be compared.

Outcome Measures
Primary Outcomes (1)
Fistula maturation rate
Proportion of patients with usable arteriovenous fistula at the end of the study (being able to deliver the prescribed dialysis dose 75% of the sessions in the first 4 weeks of use via 2 needles)
8 weeks after randomization
Study Arms (2)
Collateral vein ligation
EXPERIMENTALLigation of collateral veins under sonographic guidance
Control
NO INTERVENTIONNo collateral vein ligation.
Interventions
Collateral venous flow will be interrupted by ultrasound-guided ligation of venous side branches.
Eligibility Criteria
You may qualify if:
- \- Patients with upper extremity autogenous AVF presenting with FTM with evidence of collaterals on ultrasound and/or clinical exam.
You may not qualify if:
- Age under 18 years
- Pregnant women
- Prior endovascular or surgical procedure in the fistula after its creation (with the exception of surgical superficialization or mobilization)
- Clinical evidence of infection associated with the AVF
- Uncorrectable coagulopathy (International Normalized Radio \>2.5, platelet count \<50.000/μL)
- Absence of significant venous side branches on angiogram (defined as those that arise in the initial 10 cm, including the future cannulation zone, and have maximal diameter greater than or equal to one third of the widest diameter of the fistula's main venous channel in this segment).
