New stent aims to unclog dialysis veins
NCT ID NCT04261686
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a special mesh tube called a stent graft in 100 people on dialysis whose arm veins (fistulas) had narrowed. The stent is placed to prop the vein open and improve blood flow. Researchers tracked how long the vein stayed open without needing another procedure, and checked for any safety issues within 30 days.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Covera Vascular Covered Stent (a mesh tube placed in the vein to keep it open)
What this could lead to
If it works, this stent could help people on dialysis maintain their access longer with fewer blockages and repeat procedures.
What could go wrong
This is a post-market study with no comparison group, so results may not prove the stent is better than other options. Risks include device-related complications like clotting or infection.
