The main cause of portal hypertension?

summary

Portal hypertension is a group of symptoms caused by persistent increase of portal pressure. Most of them are caused by cirrhosis, and a few are secondary to main portal vein or hepatic vein obstruction and other unknown factors. The main cause of portal hypertension? Let's talk about it

The main cause of portal hypertension?

The incidence rate of pre hepatic type is <5%. ① Thrombosis, portal vein thrombosis; Splenic vein thrombosis; Cavernous transformation of portal vein. ② Portal vein or splenic vein was compressed or infiltrated by foreign tumor or pseudopancreatic cyst, or portal vein tumor thrombus.

The incidence rate of intrahepatic type was 90%. ① Presinural early schistosomiasis, congenital liver fibrosis, idiopathic portal hypertension, early primary biliary cirrhosis, cholangitis, hepatolenticular degeneration, arsenism, azathioprine hepatotoxicity, myelofibrosis (early), sarcoidosis, myeloproliferative diseases, etc. ② Sinusoidal / mixed hepatitis cirrhosis, alcoholic cirrhosis, fatty liver, incomplete septal fibrosis, regenerative hyperplasia of hepatic nodules, vitamin A poisoning, methotrexate poisoning, advanced schistosomiasis and cholangitis, etc. ③ Retrosinusoidal hepatic vein thrombosis or embolism, Budd Chiari syndrome, etc.

Posthepatic type was 1%. Inferior vena cava occlusive disease, constrictive pericarditis, chronic right heart failure, tricuspid insufficiency (congenital, rheumatic), etc. Pre sinus type: early schistosomiasis, congenital liver fibrosis, idiopathic portal hypertension, early primary biliary cirrhosis, cholangitis, hepatolenticular degeneration, arsenism, azathioprine hepatotoxicity, myelofibrosis (early), sarcoidosis, myeloproliferative diseases, etc.

matters needing attention

Reasonable application of protein. The liver is the site of protein synthesis, and 11-14g albumin is synthesized by the liver every day. When liver cirrhosis occurs, the liver can't synthesize proteins very well. At this time, we need to reasonably arrange the protein intake to prevent the occurrence of hepatic encephalopathy. You can choose from a variety of sources of protein food.
