Summary

This study aims to validate the Caprini score, a tool that estimates blood clot risk, in 3,000 people undergoing varicose vein surgery. Participants will be followed for four weeks after procedures like laser treatment or vein stripping to see if the score accurately predicts who develops clots. The goal is to help doctors decide which patients need blood-thinning medication after surgery.

What this could mean

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

What this could lead to: If successful, this could give doctors a reliable tool to identify patients at high risk of blood clots after varicose vein surgery, allowing targeted preventive care.
What could go wrong: This is an observational study, not a treatment trial. The Caprini score may not prove accurate enough in this specific group, and results may not apply to all surgery types.
