Radiological treatment for blocked portal vein in children

This study looks at blood problems in people who have a blockage in the main vein outside the liver (called extrahepatic portal vein obstruction). It aims to understand how this condition affects blood counts and clotting, which could help with future care.

This study tests a new way to stop bleeding from enlarged veins in the esophagus or stomach caused by a blocked portal vein. It uses an approach through a different vein in the belly, for people who can't have or didn't benefit from the usual shunt procedure.

This trial looks at whether placing a small metal stent in the portal vein and nearby veins can improve problems caused by major narrowing (or clotting) of these vessels in people with gastrointestinal cancers. If you have significant vessel narrowing, the study may offer a targeted way to relieve pressure and symptoms that are not caused by the tumor directly.

This study tests a combined procedure to stop bleeding from enlarged veins in the food pipe (varices) in people with a rare condition called cavernous transformation of the portal vein. The treatment involves blocking the bleeding veins and reducing blood flow to the spleen to prevent future bleeding.

This study is looking at better ways to treat bleeding from enlarged veins in the esophagus or stomach that happen because of portal hypertension (high blood pressure in the liver's blood vessels). It compares different endoscopic (camera) and interventional procedures to see which is safest and most effective.

This study looks for ways to predict if a child with portal hypertension (high blood pressure in the liver's blood vessels) has enlarged veins in the esophagus, without needing an endoscopy. It aims to use simple blood tests and spleen size to identify children who may need further monitoring.
