Glue vs. heat vs. knife: which vein fix wins?

NCT ID NCT03820947

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a medical glue called VenaSeal against heat therapy or surgery for treating venous reflux, a condition where leg veins don't pump blood properly. About 500 adults with early to advanced vein disease took part. The goal was to see which method patients liked more and how well it closed the bad veins.

Active substance

VenaSeal™ System (medical adhesive)

What this could lead to

If successful, VenaSeal could offer a less painful, needle-free alternative to heat or surgery for closing faulty veins, improving recovery and satisfaction.

What could go wrong

The trial was terminated early, so results may be incomplete. Long-term effectiveness compared to standard treatments is still uncertain.
