Ultrasound is the first-line imaging examination to be performed in patients with suspected cirrhosis and/or portal hypertension. Ultrasound is safe, can be repeated easily, is not expensive and is highly sensitive in detecting thrombosis in the portal vein and hepatic veins, so allowing a correct differential diagnosis of new cases of portal ...

2023年3月12日 · Liver cirrhosis is usually characterized by changes in liver volume distribution (right lobe hypotrophy, left lobe hypertrophy, caudate lobe hypertrophy), surface nodularity, rounded margins, heterogeneity, brightness, and coarsening of the hepatic architecture.

2008年1月1日 · Nowadays, ultrasonography is widely available in medical practice for the evaluation of liver cirrhosis and portal hypertension. Real-time ultrasonography (RTUS) is very convenient and is valuable in the detection of liver cirrhosis by demonstrating liver surface nodularity, splenomegaly and right lobe atrophy.

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.

2024年11月27日 · Endoscopic ultrasound (EUS) has emerged as a promising diagnostic tool, offering high-resolution imaging of the portal venous system, hepatic vasculature, and surrounding structures. This review aims at providing an overview of the evolving role of EUS in PH evaluation in patients with liver disease.

2022年2月18日 · Induced hepatic fibrosis causes stagnation of blood flow to the liver, leading to portal hypertension (PHT). Portal hemodynamics are essential for a comprehensive understating of the pathophysiology in cirrhosis [1, 2, 3].

Portal hypertension, defined as increased pressure in the portal vein, develops as a consequence of increased intrahepatic vascular resistance due to the dysregulation of liver sinusoidal endothelial cells (LSECs) and hepatic stellate cells (HSCs), …

Chronic liver disease is still a major problem because disease progression will ultimately lead to liver cirrhosis. Portal hypertension is the hallmark in advanced liver disease management. By establishing portal vein access, endoscopic ultrasound …
