Summary

This study is testing a device called Laser Speckle Contrast Imaging (LSCI) that uses a laser to measure blood flow in the leg. The goal is to see if it can help doctors monitor blood flow before, during, and after surgery to restore circulation. The study will enroll 30 people scheduled for leg revascularization surgery. Researchers will compare the LSCI readings with standard temperature measurements and another imaging method.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Laser Speckle Contrast Imaging device
What this could lead to: If successful, this could give surgeons a new, non-invasive way to monitor blood flow in real time during leg surgery, potentially improving outcomes.
What could go wrong: This is a small, early feasibility study with only 30 participants. The device may not prove reliable or useful enough to change current practice.
