The simultaneous occurrence of an intrahepatic hepatoportal fistula and portal hypertension generates questions about the priority and methods of treatment. Catheter embolization of the small-to-moderate fistula is not required, and surgical decompression of portal hypertension is recommended.

Background And Aim: There is paucity of data about the prevalence of cirrhosis and portal hypertension in the US general population.
Methods: We used National Health and Nutrition Examination Surveys (NHANES 2017-2020) to estimate the prevalence of cirrhosis and clinically significant (CS)-portal hypertension in alcoholic liver disease (ALD), MetALD, viral hepatitis (VH) to include chronic hepatitis B (CHB) and chronic hepatitis C (CHC), and metabolic dysfunction-associated steatotic liver disease (MASLD). Cirrhosis was evaluated using liver stiffness measurement (LSM) by transient elastography or FIB-4 score; CS-portal hypertension was defined via LSM and platelet count or the use of non-selective beta-blockers in the presence of cirrhosis.

Goals: To explore dynamic contrast-enhanced ultrasound (CEUS) parameters in predicting hepatic vein pressure gradient (HVPG) for patients with liver cirrhosis (LC).
Background: Noninvasive diagnosis of HVPG remains a challenge.
Study: This prospective study included patients with LC undergoing hepatic vein catheterization and pressure measurement at the hospital from May 2021 to January 2023.
Machine learning prediction of hepatic encephalopathy for long-term survival after transjugular intrahepatic portosystemic shunt in acute variceal bleeding.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for managing complications of portal hypertension, particularly acute variceal bleeding (AVB). While effective in reducing portal pressure and preventing rebleeding, TIPS is associated with a considerable risk of overt hepatic encephalopathy (OHE), a complication that significantly elevates mortality rates.
Aim: To develop a machine learning (ML) model to predict OHE occurrence post-TIPS in patients with AVB using a 5-year dataset.

Hemodynamic processes from the portal vein(PV) to the inferior vena cava(IVC) were mimicked for three patients with portal hypertension(PH) and the effects of stent parameters on the outcomes of transjugular intrahepatic portosystemic shunt(TIPS) were investigated through computational fluid dynamics(CFD). The liver region was simulated with porous media model and the spatial distributions of superior mesenteric vein(SMV) and splenic vein(SV) blood were solved through the Eulerian multiphase model. The present method is able to simulate the PH flow and predict the PV pressure, the stent shunt rate and the SMV blood proportion after TIPS treatment.

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two distinct pulmonary vascular complications seen in patients with liver disease and/or portal hypertension. HPS is characterized by disturbed gas exchange and hypoxemia because of intrapulmonary vascular dilatations. POPH is defined by pulmonary arterial hypertension, which might lead to right heart failure.
