Active clinical trials for "Hypertension, Portal"

This is a multicenter, randomized, double-blind, placebo-controlled study on the effectiveness of treatment with beta-blockers to prevent decompensation of cirrhosis with portal hypertension.

This is a diagnostic accuracy study. Eligible individuals will be enrolled and asked to undergo ds-MCE and EGD examinations. EGD is the reference standard against which ds-MCE is compared, and it will be performed within 48 hours after ds-MCE examination. The primary outcome is the sensitivity and specificity of ds-MCE in identifying the presence of esophagogastric (EGV) in patients with cirrhosis, using detection by EGD as the reference. The diagnostic accuracy of ds-MCE in detection of high-risk EV, high-risk EGV, EV, large EV, red signs of EV, GV, cardiofundal GV and PHG compared with the EGD will also be assessed. The incidence of PHE in small bowel under ds-MCE, the examination time of ds-MCE and EGD procedures, patient satisfaction assessment and safety evaluation will also be evaluated.

The purpose of this study is to determine whether Apixaban, Warfarin and Aspirin Anticoagulation are effective and safe in Prevention of Portal Vein Thrombosis in Liver Cirrhotic Patients after Laparoscopic Splenectomy

The primary purpose of this study is to evaluate the safety and efficacy of partial splenic artery embolization in the treatment of symptomatic portal vein hypertension. A secondary aim is to evaluate the relative efficacy of two separate splenic artery embolization techniques, coiling versus particle embolization of the spleen. These two methods will be compared to standard medical management which consist of pain management and fluid draining.

The aim of this study is to investigate the effects of spironolactone on liver fibrosis progression and portal pressure gradient in patients with advanced chronic liver disease. Eligible cirrhosis patients were 2:1 randomized to either combination (carvedilol and spironolactone) or single (carvedilol) therapy group. Changes in virtual portal pressure gradient (vPPG) of portal trunk (calculated based on reconstructed 3D model and measured blood flow velocity), liver stiffness measurement (Fibroscan) and serum markers of liver fibrogenesis were documented at baseline and six months later.

The aim of this diagnostic study is to evaluate the efficacy of ARFI imaging (a specific type of ultrasound) in assessing the pressure of the portal vein (the major vein passing through the liver) and the amount of liver fibrosis in patients with chronic liver disease.

Background: Variceal bleeding is a major cause of morbidity and mortality in patients with Non Cirrhotic Portal Hypertension (NCPH). Beta blockers (BB) and endoscopic variceal ligation (EVL) have been used to prevent rebleeding in these patients, largely based on data from cirrhotic patients. Endotherapy in the form of EST has been well studied in preventing rebleed in patients with NCPH. Initial studies showed that EST significantly reduced the rebleeding rate in patients of NCPH. Data from these studies suggests a rebleed rate of approximately 25% at 2yr and 35% at 5 years. Beta blockers have been found to be quite effective in both primary as well as secondary prophylaxis of variceal bleeding in cirrhotic and are accepted mode of treatment. In contrast to liver cirrhosis, published data on the effect of beta blocker therapy on NCPH are scanty. Animal data and human data suggests that beta blockers reduce portal pressure in patients with NCPH. In two placebo controlled trials of propranolol on secondary prophylaxis of variceal bleeding in non cirrhotic patients. both studies demonstrated the efficacy of propranolol in decreasing rebleed rate. However, no comparisons hae been made with EVL till date. Hypothesis: The investigators hypothesis that In patients with NCPH, treatment with beta blockers will lead to reduction in portal pressure and decrease in portosystemic shunting leading to reduction in variceal rebleeding Aim of the study: Aim: To compare the efficacy and safety of Propranolol and EVL in the prevention of variceal rebleeding in patients with NCPH.

The purpose of this study is to learn whether timolol is useful in preventing or delaying the appearance of gastroesophageal varices, a complication that may develop in the future as a consequence of liver disease. Cirrhosis causes an increased resistance of blood flowing through the liver. This leads to an increased pressure in the portal vein (the vein that takes blood to your liver). High portal pressure is responsible for the appearance of complications of chronic liver disease such as varices and variceal bleeding (bleeding from veins in your esophagus). Timolol belongs to a group of medications called beta-blockers. Beta-blockers decrease high portal pressure and previous studies have shown that beta-blocker pills are useful in preventing bleeding from varices in patients who already have varices. A more desirable effect would be if these pills could prevent not only bleeding from varices but the appearance of varices (and therefore of bleeding).

Endoscopic variceal ligation (EVL) is used to control and prevent variceal bleeding in patients with liver cirrhosis, but it can be complicated by bleeding from post-EVL ulcers. the current study aims at evaluating the potential benefit of different acid-suppressive therapies in prevention of post band ligation ulcer/bleeding. We will include 234 patients with cirrhotic portal hypertension undergoing endoscopic band ligation. Patients will be randomly allocated into one group of acid suppressive therapy (Vonoprazan or pantoprazole) versus placebo for 14 days. Re-endoscopy will be done after 2 weeks of treatment to assess the healing of post ligation ulcers. Any form of upper gastrointestinal bleeding will be documented.

Patients with large esophageal varices who have not yet experienced bleeding, are normally treated with propranolol, a beta blocking agent that reduces the portal pressure and thereby diminish the risk of bleeding. 20-40% of the patients do not respond to this treatment or have to discontinue the treatment because of side effects. The aim of this study is to evaluate if carvedilol (a combined alfa -beta blocker) has better efficacy and safety than propranolol in lowering the portal pressure in patients with cirrhosis.
