Ultrasound clot size may predict chronic leg pain after DVT

NCT ID NCT06385353

First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times

Summary

This study looks at 400 people with a first-time deep vein thrombosis (DVT) in the leg. Researchers want to see if the amount of clot seen on an ultrasound can predict who will develop post-thrombotic syndrome (PTS), a condition causing long-term leg pain, swelling, and skin changes. By identifying high-risk patients early, doctors hope to prevent or reduce the severity of PTS.
