Desperate measure: rerouting veins to save legs from amputation
NCT ID NCT06277362
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a procedure that connects an artery to a vein in the foot to bring blood to tissues when standard treatments have failed. It includes 50 patients with severe leg artery disease and active wounds. The goal is to see if the procedure is safe and can prevent major amputation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- percutaneous deep foot venous arterialization procedure
- What this could lead to
- If it works, this could provide a way to save limbs and avoid amputation in patients with severe leg artery disease who cannot have standard treatments.
- What could go wrong
- This is an early study with only 50 participants, so results may not apply to everyone. The procedure carries risks like bleeding, infection, or failure to restore blood flow.
