The gold standard to assess the presence and severity of portal hypertension remains the hepatic vein pressure gradient, however the recent development of non-invasive assessment using elastography techniques offers valuable alternatives. In this review, we discuss the diagnostic accuracy and utility of such techniques in patients with portal hypertension due to cirrhosis. Areas covered: A literature search focused on liver and spleen stiffness measurement with different elastographic techniques for the assessment of the presence and severity of portal hypertension and oesophageal varices in people with chronic liver disease...

BACKGROUND: Variceal bleeding is a common and life-threatening complication in patients with liver cirrhosis. Screening with upper endoscopy is recommended but is uncomfortable to patients. Non-invasive assessment with transient elastography for liver/spleen stiffness measurement (LSM and SSM) is accurate in detecting varices. AIMS: To test the hypothesis that a new screening strategy for varices guided by LSM/SSM results (LSSM-guided) is non-inferior to universal endoscopic screening in detecting clinically significant varices in patients with cirrhosis...

Liver stiffness measurement (LSM) by ultrasound-based elastography may be used to non-invasively discriminate between the stages of liver fibrosis, rule out cirrhosis and follow its evolution, including the prediction of the presence of oesophageal varices. The same is possible in order to diagnose clinically significant portal hypertension, referring primarilyto transient elastography and LSM values ≥20-25 kPa. The same approach may be used to reliably rule out the presence ofoesophageal varices (LSM <20 kPa + platelets >150x109/L)...

Postoperative liver failure (PLF) is the primary cause of morbidity and mortality after hepatic resection for hepatocellular carcinoma (HCC). In this study, we evaluated the efficacy of liver stiffness (LS) and spleen stiffness (SS), as measured by transient elastography (TE), for predicting the risk of PLF and overall survival (OS) in these patients.This prospective cohort study included 54 patients diagnosed with HCC who underwent hepatic resection between March 2013 and March 2014. Preoperative measurement of LS and SS using TE was performed on all patients underwent...

OBJECTIVES: Liver fibrosis (LF) is crucial for the individualized management of patients with hepatitis C virus (HCV). We evaluated the concordance between two noninvasive methods for staging LF, transient elastography (TE) and acoustic radiation force impulse (ARFI), in patients coinfected with human immunodeficiency virus and HCV. We propose an algorithm for optimal use of both techniques in routine clinical practice. METHODS: A total of 89 human immunodeficiency virus/HCV-coinfected patients underwent TE and ARFI on the same day...

Food intake increases liver stiffness, but it is believed that liver stiffness returns to baseline two hours after a meal. The aim of this study was to investigate the impact of different sized meals on liver stiffness. Liver and spleen stiffness was measured with transient elastography (TE) and real-time 2-dimensional shear wave elastography (2D-SWE). Patients ingested a 625 kcal and a 1250 kcal liquid meal on two consecutive days. We measured liver and spleen elasticity, Controlled attenuation parameter (CAP) and portal flow at baseline and after 20, 40, 60, 120 and 180 minutes...

This study evaluated whether the stiffness of the liver and spleen, measured using the point shear wave elastography (pSWE) technique, correlates with portal venous pressure (PVP) and whether the result extends to estimate the diminishing change in PVP (ΔPVP) in patients with decompensated cirrhosis. We evaluated the data of 67 prospectively enrolled patients who underwent both transjugular intrahepatic portosystemic shunt (TIPS) and pSWE. The stiffness of liver and spleen were evaluated by measuring shear wave velocity (SWV) to determine the statistical correlation with PVP...

Portal hypertension is a major pathophysiology in patients with cirrhosis. Portal pressure is the gold standard to evaluate the severity of portal hypertension, and radiological intervention is the only procedure for pressure measurement. Ultrasound (US) is a simple and noninvasive imaging modality available worldwide. B-mode imaging allows broad applications for patients to detect and characterize chronic liver diseases and focal hepatic lesions. The Doppler technique offers real-time observation of blood flow with qualitative and quantitative assessments, and the application of microbubble-based contrast agents has improved the detectability of peripheral blood flow...

Portal hypertension (PH) leads to serious complications, such as bleeding from gastroesophageal varices, ascites and portosystemic encephalopathy in patients with chronic liver disease (CLD). Gold standard methods for assessing PH and its complications include the measurement of hepatic venous pressure gradient and endoscopy; however, these are invasive, expensive and not available at all centres. Therefore, non-invasive alternatives have been the subject of extensive investigation over the last 20years. The present review focuses on the role of ultrasound elastography - a novel group of non-invasive techniques used to measure stiffness in target organs...

A 69-year-old male patient was incidentally diagnosed with a 5-mm lesion in the pancreatic tail by endoscopic ultrasound (EUS). After contrast-enhanced EUS and EUS-elastography, all imaging features were highly suggestive of a benign pancreatic solid lesion such as an intrapancreatic accessory spleen (IPAS) or a benign neuroendocrine tumor. Interposition of the splenic artery precluded EUS-guided fine-needle aspiration (FNA). When an asymptomatic pancreatic mass is detected, IPAS diagnosis should be considered, and, if EUS-FNA is infeasible, contrast-enhanced EUS and EUS-elastography are useful tools to differentiate a pancreatic benign lesion as IPAS from a malignancy, with avoidance of unnecessary surgery...

Up to now, there are no reliable biochemical markers or imaging that could reveal early tissue damage in Gaucher disease. Therefore, we addressed whether elastography technique can serve as a tool for evaluating patients with Gaucher disease. The study included 42 patients with Gaucher disease type I and 33 patients with liver cirrhosis as well as 22 healthy volunteers. Ultrasound and Doppler examination was performed on each participant prior to apply transient and 2D shear wave elastography. In Gaucher disease the median stiffness of the spleen as assessed by transient elastography (TE) and shear wave elastography (SWE) was 35KPa and 22KPa respectively in contrast to the median stiffness of healthy controls (16...
