Cirrhotic Portal Hypertension Detection System
Background Information Of Portal Hypertension
Portal hypertension is hypertension (high blood pressure) in the hepatic portal system – made up of the portal vein and its branches, that drain from most of the intestine to the liver. Portal hypertension is defined as a hepatic venous pressure gradient. Cirrhosis (a form of chronic liver failure) is the most common cause of portal hypertension; other, less frequent causes are therefore grouped as non-cirrhotic portal hypertension. When it becomes severe enough to cause symptoms or complications, treatment may be given to decrease portal hypertension itself or to manage its complications. —— Wikipedia
Cirrhosis is an end liver disease with very high incidence in China.
Portal hypertension is the most common complication of cirrhosis. Depending on the patient's different portal pressures, patients can be risk stratified to accurately guide subsequent treatment decision and clinical management.
Portal Hypertension Measurement
Conventional portal hypertension measurement
The hepatic vein wedge pressure and free pressure were measured by jugular vein cannulation, and the difference between the two was obtained as hepatic venous pressure gradient, which reflected the portal vein pressure.
Based on CT imaging and radiomics technology, the massive features of liver and spleen were extracted and analyzed, and patients were classified according to different portal hypertension risks.
Cost about1/10 of the conventional method.
