New hope for leg pain: catheter treatment targets Post-Clot syndrome

NCT ID NCT03250247

First seen Nov 03, 2025 · Last updated Jun 16, 2026 · Updated 25 times

Summary

This study tests whether a catheter-based procedure can reduce symptoms and improve daily life for people with long-term leg pain, swelling, or ulcers caused by old deep vein clots. About 225 adults with disabling post-thrombotic syndrome and a blocked iliac vein will receive either the procedure plus standard care or standard care alone. The goal is to see if the procedure safely eases symptoms and helps people get back to normal activities.
