A small amount of ascites usually has no obvious symptoms, while a large amount of ascites caused by different etiologic factors often suggests that the patient’s liver is suffering from different serious lesions, such as excessive hepatic portal pressure, loss of compensatory phase or cancerous thrombus formation in the liver. 1. Impaired liver function: viral hepatitis leads to the formation of hepatic ascites, which indicates that the liver is damaged and loses its normal metabolic function, and acute or chronic hepatic failure may occur, such as hepatic encephalopathy, which is characterized by recurrent coma. 2. Hypoproteinemia, decompensated liver function: ascites in patients with liver cirrhosis often suggests that the patient enters the decompensated stage, i.e., advanced stage of cirrhosis, at this time, the liver hardens, resulting in excessive portal vein pressure, and there is a marked decline in liver function, such as hypoproteinemia, decreased blood circulation. Clinical manifestations are malnutrition and wasting, fatigue and weakness. 3. Portal hypertension, hepatic cancerous thrombosis: ascites caused by liver tumor suggests that the patient has liver complications, and the tumor affects the surrounding vascular tissues, such as intensification of cirrhosis, portal hypertension or hepatic vein cancerous thrombosis. This is reflected by the presence of filling defects in the veins on imaging. Severe ascites is often indicative of severe liver failure and serious disease, so ascites should be treated immediately.
