Dialysis fistula fix? study pulled before it began
NCT ID NCT03365089
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if tying off extra veins (collaterals) could help dialysis fistulas mature so they can be used for treatment. It planned to enroll patients whose fistulas were not developing properly. However, the trial was withdrawn before any participants were enrolled, so no conclusions can be drawn.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- collateral vein ligation (a procedure to tie off extra veins near the fistula)
- What this could lead to
- If it had worked, this could have pointed to a simple way to help more dialysis fistulas become usable, reducing the need for additional procedures.
- What could go wrong
- The trial was withdrawn before any patients were enrolled, so we have no data on whether the procedure is effective or safe. It remains an unproven idea.
