BACKGROUND & AIMS: To investigate prognostic value of varices on CT and redefine surrogate criteria for clinically significant portal hypertension (CSPH). METHOD: We retrospectively enrolled 241 patients with compensated cirrhosis who underwent hepatic venous pressure gradient (HVPG) measurement from 2008 to 2013. Using CT and upper endoscopy findings obtained within 3 months from HVPG measurement, patients were classified into three groups: presence of standard surrogate for CSPH, defined as presence of varices on upper endoscopy and/or splenomegaly associated with thrombocytopenia (Group 1, n=139); varices on CT without standard surrogate for CSPH (Group 2, n=41); and free from both (Group 3, n=61)...

INTRODUCTION: Cirrhosis as a pathological term has some criteria known to be common in all cases of liver cirrhosis. Esophageal varices are portosystemic collaterals arising in the submucosa of the lower esophagus because of portal hypertension. Portal hypertension is defined as hepatic venous pressure gradient greater than 5 mmHg that arises often as a sequelae of mesenchymal dysfunction in a cirrhotic liver. This study was carried out on 120 personnel divided into three groups: group A included 50 cases of liver cirrhosis with esophageal varices, group B consisted of 50 cases of cirrhosis without esophageal varices, and group C had 20 healthy volunteers a control group...

PURPOSE OF REVIEW: The current review aims to explain the different systems available to clinicians for predicting clinical outcomes in patients with cirrhosis. RECENT FINDINGS: Cirrhosis is the final stage of chronic liver disease and is associated with high morbidity and mortality. The most commonly utilized tools to predict outcomes in patients with cirrhosis include the following: assessing severity of portal hypertension using hepatic venous pressure gradient (HVPG) measurements, using scoring systems such as the Model for End-stage Liver Disease (MELD) and Child-Pugh-Turcotte (CPT) scores, and recently, clinical staging systems based on cirrhosis-related clinical complications...

BACKGROUND: The impact of portal hemodynamic variations after portal vein embolization on liver regeneration remains unknown. We studied the correlation between the parameters of hepatic venous pressure measured before and after portal vein embolization and future hypertrophy of the liver remnant after portal vein embolization. METHODS: Between 2014 and 2017, we reviewed patients who were eligible for major hepatectomy and who had portal vein embolization. Patients had undergone simultaneous measurement of portal venous pressure and hepatic venous pressure gradient before and after portal vein embolization by direct puncture of portal vein and inferior vena cava...

Liver stiffness (LS) as measured by transient elastography is increasingly used to non-invasively assess liver fibrosis. However, LS is efficiently modulated by confounders like arterial and portal pressure (PP). We here study the effect of acute hemodynamic changes on LS (measured by µFibroscan) in a rodent model of cirrhosis in response to pharmacological modulation of PP by losartan, NO-donors and propranolol. Additionally, changes of LS and the hepatic venous pressure gradient (HVPG) under propranolol therapy were assessed with regard to clinical outcomes in a human cohort of n=38 cirrhotic patients...

OBJECTIVES: Spleen stiffness (SS) correlates with liver stiffness (LS) and hepatic venous pressure gradient. The latter is currently the most accurate predictor of hepatic decompensation. Our study aims to check whether SS has a similar predictive capability, while being an easy-to-perform noninvasive test in a real-life patient cohort. METHODS: Concomitantly, 210 successive patients were examined and received liver and SS measurements and a standard laboratory...

Hepatic venous pressure gradient (HVPG) is a widely employed surrogate of portal pressure gradient (PPG) in the diagnosis of portal hypertension (PHT). However, little is known about how HVPG measurement is affected by the complex vascular changes associated with PHT. In this study, we employed a computational method to quantitatively evaluate the sensitivity of HVPG measurement to various vascular factors involved in the development of sinusoidal PHT, aiming to provide a theoretical reference to guide the clinical application of HVPG measurement...

The present study was designed to investigate the functional status of β2 adrenoceptors (β2AR) in two models of chronic inflammatory disease: liver cirrhosis (LC) and osteoarthritis (OA). The β2AR gene contains three single nucleotide polymorphisms at amino acid positions 16, 27 and 164. The aim of the present study was to investigate the potential influence of lymphocyte β2AR receptor functionality and genotype in LC and OA patients. Blood samples from cirrhotic patients (n=52, hepatic venous pressure gradient 13±4 mmHg, CHILD 7±2 and MELD 11±4 scores), OA patients (n=30, 84% Kellgren‑Lawrence severity 4 grade, 14% knee replacement joint) and healthy volunteers as control group (n=26) were analyzed...

Microvesicles (MVs) are extracellular vesicles released by cells following activation or apoptosis. Some MV subpopulations augment with cirrhosis severity and contribute to portal hypertension. This study aimed at determining if plasma MV levels can estimate the presence of hepatic venous pressure gradient (HVPG) ≥10 mm Hg and predict mortality in patients with advanced chronic liver disease. All patients with severe fibrosis or cirrhosis undergoing liver catheterization between 2013 and 2015 at two centers were prospectively included...

BACKGROUND: Various methods are used to reduce venous blood pressure in the hepato-splanchnic circulation, and hence minimise blood loss during liver surgery. Previous studies show that combination of vasopressin and nitroglycerin reduces portal pressure and flow in patients with portal hypertension, and in this study we investigated this combination in patients with normal portal pressure. METHOD: In all, 13 patients were studied. Measurements were made twice to confirm baseline (C1 and BL), during vasopressin infusion 4...

Portal hypertension secondary to liver cirrhosis may cause a number of life-threatening complications. The rupture of gastroesophageal varices is associated with a high mortality rate of 15-30%. Hepatic venous pressure gradient (HVPG) is an accurate reflection of disease severity, however this can only be assessed via an invasive interventional procedure. The aim of the present study was to explore a non-invasive method based on 3D computed tomography (CT) volume rendering technology to accurately predict HVPG...

Does transjugular intrahepatic portosystemic shunt stent (TIPS) improve survival in a subgroup of patients? Yes. TIPS nearly halves portal pressure and increases the effective blood volume. In cases of acute variceal hemorrhage and with a high risk of treatment failure, defined as either hepatic venous pressure gradient higher than 20 mm Hg, Child B with active bleeding at the endoscopy, or Child C with less than 14 points, early or preemptive placement of TIPS (within 72 hours) improves survival. Also, in suitable patients with intractable or refractory ascites, TIPS improves survival if placed early in the course of treatment...
