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.
