Hepatic vascular disorder

This trial tests whether giving praziquantel three times a year, instead of the standard once a year, can improve liver fibrosis (scarring) caused by schistosomiasis in people aged 15-40 in Uganda. Participants with liver fibrosis will be randomly assigned to one of two treatment…

This study tests whether a procedure called proximal splenic artery embolization (PSAE) can reduce the need for repeated fluid drainage in adults with cirrhosis and ascites that no longer responds to water pills and diet. Participants will undergo a one-time procedure where small…

This trial tests whether an absorbable gelatin sponge works as well as cyanoacrylate glue for closing off enlarged stomach veins that can bleed. Both treatments are delivered via endoscopy with small coils. Participants are adults with a history of bleeding from these veins, and …

This study tests a new procedure for people with a completely blocked main portal vein who have had at least two episodes of dangerous variceal bleeding. Doctors will use ultrasound to guide a needle into a vein in the gut, then try to reopen the blocked vein or create a new bypa…

This study tests whether the blood thinner rivaroxaban can safely improve outcomes in people with liver cirrhosis who have both a blood clot in the portal vein and a high risk of variceal bleeding. About 175 participants will receive rivaroxaban or standard care starting 48 hours…

This study compares a new procedure using a special stent (underdilated VCX-TIPS) with standard treatment (endoscopic banding plus beta-blockers) to prevent variceal rebleeding in people with cirrhosis. The new approach uses a smaller balloon to expand the stent, aiming to lower …

This study looks at two treatments—endoscopy and a procedure called TIPS—to prevent repeat bleeding from enlarged veins in the stomach or esophagus caused by liver disease. Over 1,000 adults with this condition will be followed for a year to see which approach works better. The g…

This study tests a fiber-optic navigation system that gives doctors a 3D view during a procedure called TIPS, which treats complications of liver cirrhosis like fluid buildup or bleeding. About 30 patients will be enrolled to see if the device reduces the number of needle sticks,…

This study tracks 152 adults with cirrhosis who receive a special stent to treat complications like fluid buildup in the belly or bleeding from enlarged veins. The stent creates a new blood-flow path in the liver. Researchers will monitor how well it works and its safety over 2 y…

This study tests a new combination of four treatments for people with liver cancer that cannot be removed by surgery and who also have high blood pressure in the liver (portal hypertension). The goal is to see if adding a blood-pressure drug (carvedilol) to standard cancer therap…

This study tests a new procedure using an endoscopic ultrasound to guide the injection of tiny particles into the spleen, reducing blood flow and lowering the risk of dangerous bleeding in people with liver cirrhosis. The goal is to see if this method is safer and more effective …

This study tests whether a special 4D-flow MRI can accurately measure blood flow and pressure in the liver without needing an invasive catheter. Researchers will enroll 60 adults with cirrhosis and compare MRI results to the standard pressure test. If it works, this could make di…

This study explores whether a special ultrasound technique, called dynamic contrast-enhanced ultrasound (DCE-US), can diagnose porto-sinusoidal vascular disorder (PSVD) without needing a liver biopsy. Researchers will compare ultrasound images from 100 people with PSVD or cirrhos…

This study looks at whether non-invasive tests like blood counts and spleen size can accurately predict the presence and severity of enlarged veins in the esophagus (varices) in children with portal hypertension. Researchers will compare these simple markers to the standard metho…

This study looks at whether a special MRI scan can safely rule out high-risk varices (enlarged veins that can bleed) in people with hepatitis B-related cirrhosis. Instead of using a camera tube down the throat (endoscopy), researchers will test an MRI-based model. If it works, ma…

This study tests whether a combination of contrast-enhanced ultrasound and spleen stiffness measurement can accurately detect high blood pressure in the liver (portal hypertension) in people with cirrhosis. Currently, doctors must insert a catheter into a neck vein to measure thi…

This phase 3 trial tests whether vonoprazan, a newer acid-blocking drug, is better than rabeprazole at preventing ulcers and bleeding after endoscopic variceal band ligation (EVL) in people with cirrhosis. About 300 adults with esophageal varices will take one of the two drugs da…

This study tests whether taking S-adenosylmethionine (SAMe), a natural supplement, can prevent liver injury caused by the chemotherapy drug oxaliplatin. About 30 adults with colorectal cancer that has spread to the liver will take SAMe pills daily for 3-6 months alongside their c…

This study tests whether adding a technique called vascular deformation mapping (VDM) to standard CT scans can better predict liver failure after major liver surgery. Researchers will analyze routine preoperative CT images from over 1,000 adults undergoing removal of at least thr…

This study looks at a rare liver condition called porto-sinusoidal vascular disease (PSVD), which is diagnosed with a liver biopsy. The researchers are collecting detailed medical information from 150 patients to track their health over time, including survival and liver-related …

This study tests new MRI techniques to measure blood flow and tissue details in the liver. Researchers will scan 110 people, including healthy volunteers and those with chronic liver disease or fibrosis, to see if these scans can reliably detect liver damage. The goal is to devel…

This study follows 30 adults with liver cirrhosis who are having their spleen removed (laparoscopic splenectomy) to treat an enlarged spleen and low blood counts. Researchers will measure kidney function before surgery and for two years after to see if the surgery helps or harms …

This study follows 30 people with liver cirrhosis and a history of bleeding from high blood pressure in the liver. They will have surgery to remove the spleen and disconnect certain blood vessels. Researchers will track kidney function for two years to see if the surgery helps or…

This study follows 30 adults with liver cirrhosis, an enlarged spleen, and hypersplenism who are having their spleen removed by keyhole surgery. Researchers will measure changes in cholesterol and other blood fats before surgery and for two years afterward. The goal is to learn w…

This study follows 30 people with liver cirrhosis who need spleen surgery to treat bleeding from high blood pressure in the liver. Researchers will check their cholesterol and fat levels before and for two years after surgery. The goal is to see if the surgery improves abnormal f…

This study looks at whether a simple, non-invasive ultrasound can predict the risk of dangerous bleeding from enlarged veins in the esophagus (varices) in people with liver cirrhosis. Researchers will measure spleen size and a key blood vessel diameter on ultrasound and compare t…

This study will follow 300 adults who have both a portosystemic shunt (an abnormal blood vessel connection between the liver and the rest of the body) and pulmonary hypertension (high blood pressure in the lungs). Researchers want to learn more about how common this combination i…

This study will follow about 2,500 adults with liver cirrhosis to learn who gets dangerous blood clots in the liver's main vein, how these clots affect survival, and whether blood-thinner medications are safe and helpful. Participants receive no experimental treatment—just routin…

This study will follow 2,500 patients with liver cirrhosis or portal hypertension who are scheduled for elective medical procedures. Researchers want to find out how often bleeding happens and what factors predict it, beyond standard blood tests. The goal is to improve safety by …
