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.
