Visceral angiography was performed in 7 patients with normal portal pressure and in 10 with portal hypertension. Circulation times, size of vessels and portal pressure were determined. At celiac angiography a direct correlation was found between time for maximum filling of portal vein and portal pressure, provided no vascular abnormalities existed. At superior mesenteric angiography such a correlation was not found; loss of flow by shunts in portal hypertension being one explanation. Portocaval shunts are common in the celiac system, but uncommon in the superior mesenteric system.

Background: Understanding venous congestion is critical to the management of many illnesses, but assessing volume status can be challenging. The current gold standard for volume status assessment of right heart catheterization (RHC) is invasive, costly, and often unavailable. Venous Excess Ultrasound Score (VExUS) is a novel ultrasound protocol for to assessment of venous congestion using the inferior vena cava, hepatic, portal and renal veins.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) placement leads to a reduction in portal pressure and an improvement in survival in patients with recurrent and refractory ascites and variceal haemorrhage. Prediction of post-TIPS survival is primarily determined by factors identified before the TIPS procedure, as data collected during or after TIPS implantation are limited. The aim of the study was to evaluate the influence of early hemodynamic changes after TIPS placement on survival, in order to refine post TIPS management.

Metabolic dysfunction-associated steatotic liver disease (MASLD), hepatic fibrosis, and portal hypertension constitute an increasing public health problem due to the growing prevalence of obesity and diabetes. C-type natriuretic peptide (CNP) is an endogenous regulator of cardiovascular homeostasis, immune cell reactivity, and fibrotic disease. Thus, we investigated a role for CNP in the pathogenesis of MASLD.

Introduction And Objectives: The portal vein pressure higher than 10 mm Hg in patients with hepatic cirrhosis is more likely to have serious complications and poor prognosis. Nonselective receptor blockers (NSBBs) can reduce the portal vein pressure; however, the efficacy and safety of different NSBBs in reducing portal vein pressure were unconsistent. A systematic review and meta-analysis was conducted to evaluate the efficacy and safety of carvedilol versus propranolol in reducing portal vein pressure in this study.

Background: HCC is characterized by a high interstitial fluid pressure (HIFP) environment, which appears to support cancer cell survival. However, the mechanisms behind this phenomenon are not fully understood.
Methods: This study investigates the role of kinesin family member 11 (KIF11) in HCC under HIFP conditions, using both in vivo and in vitro models.
