Stent procedure eases severe symptoms in cancer patients with blocked veins
NCT ID NCT07252570
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at placing a small metal tube (stent) into the portal vein of 63 cancer patients whose vein was blocked by a tumor. The goal was to relieve serious symptoms like fluid buildup in the belly or bleeding in the gut. The procedure was done through a needle in the liver, and the team checked how long the stent stayed open and how well it worked.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- self-expanding metallic stent
- What this could lead to
- If successful, this procedure could offer a minimally invasive way to relieve severe symptoms like fluid buildup and bleeding in cancer patients with blocked portal veins.
- What could go wrong
- This was a small, retrospective study with only 63 patients, so results may not apply to everyone. The procedure carries risks like bleeding or infection, and the stent may block again over time.

Who is studied
The study population consisted of consecutive adult patients referred to the Interventional Radiology Department of Nice University Hospital (CHU l'Archet, France) between April 2004 and March 2024. All patients presented with symptomatic portal hypertension related to malignant portal venous stenosis or occlusion and were treated with percutaneous transhepatic portal vein stenting. Patients were identified retrospectively from institutional medical records.
