Stockings vs. no stockings: huge trial aims to settle clot prevention debate

NCT ID NCT06166537

First seen Mar 29, 2026 · Last updated Jun 12, 2026 · Updated 13 times

Summary

This study looks at whether wearing compression stockings in the hospital, on top of taking blood-thinning medication, can further reduce the risk of dangerous blood clots after surgery. About 8,600 adults having high-risk operations (like cancer or joint surgery) will be randomly assigned to receive either blood thinners plus stockings or blood thinners alone. All participants will get an ultrasound to check for clots, and researchers will compare the two groups to see if stockings provide any extra benefit.
