Occlusive portal vein thrombosis may be a negative prognostic marker of variceal bleeding in liver cirrhosis. Compared with conventional endoscopic and pharmacological therapy, transjugular intrahepatic portosystemic shunt may further improve the outcomes of occlusive portal vein thrombosis in liver cirrhosis with variceal bleeding.
To determine if 3D ultrasound measurements can accurately measure the pressure of blood flow across a stent that has been placed in a portal vein to reduce portal vein pressure known as Transjugular Intrahepatic Porto-Systemic shunts or TIPS.
Islet transplantation is one of the effective and promising options for type 1 diabetes mellitus treatment1-4. The liver is the primary target location for infusion and portal vein catheterization is generally used. Percutaneous transjugular, percutaneous transhepatic, laparoscopically transmesenteric and laparoscopically transumbilical approaches were often utilized to access the portal. Current islet infusion approach via portal vein of liver has various defects. Percutaneous...
The PROGRESS is an investigator-initiated, multicentre, randomized, trial comparing anticoagulation, which is the currently most frequently used treatment, alone, versus transjugular intrahepatic portosystemic shunt (TIPS) combined with anticoagulation, in patients presenting with ROPVT. The rationale of this study is to significantly increase the proportion of patients that achieve a complete or partial recanalization of the portal vein. The intervention of this study consists...
Through a multicenter randomized controlled trial of TIPS to prevent post-hepatitis B cirrhosis of esophagogastric varices, the incidence of hepatic encephalopathy, the rate of stent patency, the incidence of rebleeding and survival in the left and right branches of the portal vein were compared.
During a TIPS procedure, a shunt or stent (mesh tube) is passed down the jugular vein (the vein above the collarbone in the neck) using fluoroscopy (real time x-rays) guidance. Then, a stent is inserted between the portal vein (vein that carries blood from the intestines into the liver) to a hepatic vein (vein that carries blood away from the liver back to the heart). This means that blood that would usually gets filtered through the liver is now bypassing the liver and going d...
Patients with advanced chronic liver disease may develop hypertension of the portal vein, which is the main cause for most complications and deaths of patients with liver cirrhosis. Implantation of a transjugular intrahepatic portosystemic shunt (TIPS) leads to instantaneous alleviation of portal hypertension, but may cause confusion or even lead to hepatic coma. Stents, as well as patient stratification and medical surveillance, have drastically improved over the past decades....
Portal pressure gradient (PPG) above 12 mmHg after transjugular intrahepatic portosystemic shunt (TIPS) increases the risk of portal hypertension complications. Currently, a PPG reduction
Since not every portal vein thrombus (PVT) in a patient with hepatocellular carcinoma (HCC) is a tumor thrombus, since the nature of the thrombus will ultimately determine the course of treatment, and since PVT may be even the initial sign of an undetected HCC, every effort should be made to distinguish between a tumor and a non-tumor PVT. In addition, malignant PVT does not always demonstrate neovascularity and/or enhancement, which makes fine needle aspiration (FNA) necessary...
The effect of portal hypertension on gastrointestinal motility, and how reversal or improvement in portal hypertension may alter gastrointestinal motility, remains unclear and further research is needed. Additionally, patients with cirrhosis have altered gut microflora, particularly rich in lactobacilli, including enterococci and bifidobacteria. Transjugular Intraheptic Portosystemic Shunting (TIPS) is a procedure performed by interventional radiologists, in which a connection ...
Clinically significant portal hypertension (CSPH) is associated with an incremental risk of esophageal varices and overt clinical decompensations in cirrhosis. However, hepatic venous pressure gradient (HVPG) measurement, the gold standard for defining CSPH (HVPG≥ 10mmHg) is invasive and therefore not suitable for routine clinical practice. This is a multi-center diagnostic trial conducted at 10 high-volume liver centres in China designed to determine the accuracy of deep le...
The main purpose of this exploratory study is to investigate the effect of serelaxin (RLX030) infusion on the hepatic and renal circulation in patients with compensated cirrhosis and portal hypertension. Measurements will be acquired non-invasively using magnetic resonance angiography (MRA) (study part A) and more directly via cannulation of the hepatic portal vein during a routine transjugular intrahepatic portosystemic shunt (TIPSS) check procedure (study part B), to determin...
To evaluate the values of portosystemic shunt and other interventional radiology approaches for treatment of symptomatic portal hypertension in patients with cavernous transformation of portal vein.
The aim of this study is to prospectively evaluate the tolerance and efficiency of a new technique of preoperative selective portal vein embolization (PVE) in patients requiring major hepatic resection.
The purpose of this study is to determine the effect and safety of anticoagulation after endoscopic therapy in cirrhotic patients with portal vein thrombosis and to explore its effect on long-term rebleeding rate and mortality.
To prevent portal vein thrombosis (PVT) in patients with cirrhosis at risk for PVT by pharmacologic prophylaxis with intravenous antithrombin (AT-III).
Intrahepatic non-cirrhotic portal hypertension (INCPH) is a rare disease mostly affecting adults in their forties, characterized by portal hypertension related to alterations of intrahepatic microcirculation in the absence of cirrhosis.The only therapeutic options currently available for patients with INCPH include prophylaxis for variceal bleeding using betablockers and/or endoscopic band ligation and TIPSS (transjugular intrahepatic portosystemic shunt) or liver transplantati...
This study evaluates correlation in changes of HVPG-pressure values and stiffness values (ARFI) for spleen and liver and flow-volume values in Portal vein in patients with liver cirrhosis/Portal Hypertension, respectively, after new-admission of beta-blocker therapy.
Portal hypertension is not a disease in itself. Rather, it is an indication of an illness, caused mostly by chronic lesions of the liver because of distinct causes, such as viral infection, chronic alcoholism, or metabolic disorders. Other reasons include splanchnic vascular diseases (for example, obstruction of the portal or the hepatic veins). Portal hypertension is defined as a pressure in the portal vein exceeding the vena cava pressure by more than 5 mm Hg.
Bleeding from gastroesophageal varices is one of the major complications of cirrhosis. After successful treatment of the acute bleeding episode, patients who do not receive follow-up treatment to prevent rebleeding were reported to have a rebleeding rate of 60% within 1- 2 years. The presence of liver cancer and/or portal vein thrombosis has been associated with recurrent variceal bleeding. In a study of liver cancer patients in Hong Kong, 7.9% of patients developed at least 1 ...
In this study, investigators aim to screen out the patients with portal hypertension by monitoring intraoperative PVP, and to decide the effect of Terlipressinum on the portal pressure after liver resection.
Several aspects on the use of portal vein embolization (PVE) are poorly studied and todays recommendations are based on low-grade evidence. In this Scandinavian multicenter cohort study we will study some of the controversial aspects on the use of PVE to try to provide clearer answers on its optimal use. Six tertiary university hospital hepatobiliary units in Sweden, Norway and Denmark participate and contribute with all PVE procedures performed at their units during the study ...
Open randomized therapeutic study to assess the efficacy of Xarelto 15mg/day in the recurrence of thromboembolic event compared to an untreated group in patients with chronic portal vein thrombosis without high risk thrombophilia.
The hypothesis is that liver venous deprivation (LVD) could strongly improve hypertrophy of the future remnant liver (FRL) at 3 weeks, as compared to portal vein embolization (PVE) in patient with liver metastases from colo-rectal origin considered as resectable.
This study is working to evaluate the surgical comprehensive treatment for different types of tumor thrombi in the portal vein for hepatocellular carcinoma patients, to establish a standardized, unified, effective therapeutic program.
