Why the intersection of door and the intersection of pulse and high pressure, prevention and health care, _ of splenomegaly, it will be liver cirrhosis
It is supplied that the blood supplt of the liver is dual by liver artery and portal vein. The liver artery contains abundant oxygen, it is necessary to supply one's own supersession of liver, it is a nutrition blood vessel of the liver; The portal vein refers to a bigger vein of the of liver population, intravenous from the mesenterium and the spleen vein was converged, divided into No. 2 Branch and entered people's liver on the liver door. 75% of blood of the liver come from the portal vein, 25% come from the liver artery. The portal vein is mainly responsible for collecting the intravenous reflux blood of the gullet, stomach, intestines, pancreas, gallbladder and spleen, and deliver to the liver essence, get up to the liver " processing of investor's raw materials " externally Function served as bridge. It reaches about 1 liter every minute to enter the blood of the liver from portal vein, enter the small leaf sinus crack of liver through countless liver portal vein capillary networks, then converge into three big liver veins step by step, pour into the lower vena cava and get back to the right heart directly.
At the time of liver cirrhosis, because the small leaf fiber of liver, the liver essence becomes hard, resistance increases in the liver sinus, pulse is in charge of the system in the liver ' Liver artery, liver are intravenous, portal vein and lymphatic vessel) Branches and tip branch main attenuate, twist, stiff,blood, in in charge of resistance strengthening after flowing at ^ing. Among them behind the portal vein collects the intravenous blood that the intestines and stomach flow into, the blockage of and then flowing back, silt up in the door venous system, cause the high pressure of portal vein.
Portal vein pressure rises and becomes certain, will another look for the opportunity to make the blood get back to the right heart. These tributaries seldom opened at ordinary times, open in order to relieve the pressure gradually under the circumstances that high pressure of portal vein and a large amount of blood are assaulted, thus lead to the fact the collateral circulation between portal vein and vena cava is open and have gullets, vein of fundus of stomach commonly. Vein detailed gullet and table shallow, portal vein blood stasis pour in, make its intravenous to twist the anger one in a large amount, the form is like earthworms, it is variceal to form the gullet underpart. It is variceal that in addition there are belly walls and the pile vein is expanded etc.. As the esophagus and fundus of stomach are variceal becomes certain, under external factor function, can break, cause upper digestive tract massive haemorrhage. Shown as a kind of stool of spittinging blood in a large amount or pitch; Cause the rectum vein to break and have blood in one's stool in a large amount while bleeding.
Another reason that pulse hyperbarism forms on the door is splenomegaly, but the reason of splenomegaly is liver cirrhosis. At the time of liver cirrhosis, resistance increases in the liver essence, the blood flow of the liver artery pours into the blockage, as time passes, liver artery and branch become tiny, sparse. Because of the hydromechanical function principle, when the liver artery pours into resistance to increase, abdominal cavity do artery enter blood flow of spleen, increase obviously, soft the intersection of spleen and organization nutriment that add increase in a large amount until strong blood flow bludgon into, the spleen increases to several fold even more than ten times gradually. It is high-pressure in shape that the pressure of portal vein the multiple increases because of the reflux of intravenous blood flow volume of the spleen, because splenomegaly accompanies spleen hyperfunction of hair at the same time, cause the reduction of the blood composition such as leucocyte, blood platelet, erythrocyte, cause anaemia alikely with the whole blood to reduce, the immunological function is low, organism resistance drops.
