Major complications of liver cancer for gastrointestinal bleeding, liver nodules rupture, liver failure, infection, These concurrent Liver cancer is often resulted in the direct cause of death.
HCC upper gastrointestinal bleeding is the most common serious complication is the main reason leading to liver cancer deaths. Lead, Gastrointestinal bleeding reasons:
(1) of esophageal varices Esophagus, varices lead to liver cancer, is the most important cause of gastrointestinal bleeding. The main mechanism of their occurrence: over 80 per cent of liver cancer patients with cirrhosis of the liver can lead to increased portal pressure, esophageal, gastric varices, when the portal vein or hepatic vein occlusion, may exacerbate portal hypertension, the result has varicose esophagus, gastric bleeding, the cause upper gastrointestinal bleeding; liver cancer may increase liver damage, liver cirrhosis increased, resulting in portal vein high aggravated when hepatocellular carcinoma lesions in the porta hepatis, may oppression portal trunk may also portal hypertension.
(B) coagulation mechanism obstacles Because liver cancer patients to reduce normal liver tissue, liver synthetic clotting factor reduction in clotting mechanism obstacles. By In hypersplenism, platelet destruction increased coagulation mechanism will happen obstacles. In addition, the tumor thrombus into the blood after the person is Easy to cause acute disseminated intravascular coagulation (DIC), cause gastrointestinal bleeding.
(3) gastrointestinal mucosal erosion Because patients with hepatocellular carcinoma portal hypertension, often causing gastrointestinal tract congestion, edema dynamic membrane erosion caused bleeding.
