Clinical Trial Summary

Exploring and establishing new non-invasive risk stratification techniques for portal hypertension based on E imaging technology for measuring liver and spleen stiffness is an urgent need in this field of research.

Description:

Portal hypertension is an important risk factor affecting the clinical prognosis of patients with liver cirrhosis. According to clinical practice guidelines, risk stratification based on portal vein pressure levels is crucial for predicting the prognosis of patients with cirrhotic portal hypertension, and it is one of the most important aspects in the diagnosis and treatment chain of end-stage liver diseases such as cirrhosis. The most reliable method for assessing portal vein pressure in patients with cirrhosis is the measurement of hepatic venous pressure gradient (HVPG). This is achieved by inserting a catheter into the hepatic vein via jugular vein puncture, measuring the free and wedged pressures, and calculating the difference to obtain HVPG. HVPG provides important information regarding treatment response, complication risks, and long-term prognosis for patients with cirrhotic portal hypertension: HVPG ≥ 10mmHg indicates an increased risk of varices, decompensation events, and hepatocellular carcinoma in compensated cirrhosis patients, HVPG ≥ 12mmHg is a high-risk factor for variceal bleeding, HVPG ≥ 16mmHg suggests an increased risk of death in patients with cirrhotic portal hypertension, and HVPG ≥ 20mmHg indicates higher failure rates of hemostatic treatment and increased mortality risk in patients with acute variceal bleeding. However, there are some issues with measuring HVPG, including invasiveness, technical requirements, and high costs, which limit its clinical application. The development of non-invasive assessment techniques for portal hypertension in cirrhosis has always been a hotspot and difficulty in this field.

In recent years, with the rapid development of ultrasound elastography technology, it has also been widely used in the field of liver diseases. Transient elastography, point shear wave elastography, and two-dimensional shear wave elastography (referred to as E imaging) all have important value in the non-invasive assessment of portal hypertension in cirrhosis. Ultrasound elastography, due to its advantages of non-invasiveness, rapidity, ease of operation, repeatability, safety, and ease of follow-up monitoring, is of great significance in risk stratification, precise management, and efficacy evaluation of portal hypertension in cirrhosis. Although liver stiffness has been applied in the diagnosis, treatment, and prognosis assessment of cirrhotic portal hypertension, transient elastography is still the main ultrasound elastography technique used clinically, and there are relatively few original studies related to spleen stiffness. Therefore, there is currently a lack of high-level clinical evidence based on E imaging technology for evaluating portal hypertension in cirrhosis in China, as well as a lack of original research on spleen stiffness assessment in cirrhotic portal hypertension.

In summary, exploring and establishing new non-invasive risk stratification techniques for portal hypertension based on E imaging technology for measuring liver and spleen stiffness is an urgent need in this field of research.

Intervention

Diagnostic Test:
• Hepatic venous pressure gradient
HVPG is a measurement used to assess portal hypertension, a condition characterized by increased blood pressure in the portal vein, which carries blood from the digestive organs to the liver. HVPG measurement involves inserting a catheter into the hepatic vein via jugular vein puncture to directly measure the pressure within the liver. By comparing the pressure in the hepatic vein with that in the portal vein, HVPG provides valuable information about the severity of portal hypertension and helps in predicting clinical outcomes in patients with liver cirrhosis and related conditions. HVPG measurements are crucial in guiding treatment decisions, assessing treatment response, and predicting the risk of complications such as variceal bleeding and liver failure.
• Two-Dimensional Shear Wave Elastography
2D-SWE is a non-invasive imaging technique used to assess tissue stiffness, particularly in the liver. This technology utilizes ultrasound to generate shear waves within the tissue being examined. By measuring the speed of these shear waves as they propagate through the tissue, 2D-SWE can provide quantitative information about tissue elasticity or stiffness. In the context of liver disease, including cirrhosis and fibrosis, 2D-SWE is valuable for evaluating the degree of liver stiffness, which correlates with the severity of liver fibrosis. This information aids in diagnosis, staging, and monitoring of liver diseases, allowing for early detection of complications and assessment of treatment response. Compared to traditional biopsy-based methods, 2D-SWE offers the advantage of being non-invasive, rapid, and repeatable, making it a preferred modality for assessing liver stiffness in clinical practice.
