Is it hyperfunction why the liver cirrhosis patient the spleen function take place? 's general knowledge
The spleen is that one stores blood organ, made up of white marrow and red marrow, white marrow is formed by intensive lymphoid tissue, it is the main distribution area of T cells, play a immune role, red marrow is asked for by spleen sinus and spleen and made up, have a large number of macrophages, B lymphocytes and plasma cells, the blood arises to filter and remove foreign matter function. The blood cell in the blood is mainly asked for through the spleen --The base membrane aperture among the blood sinuses, just enter the blood sinus, reach the spleen vein. The diameter only 2-3um of membrane aperture of these bases, and the diameters of erythrocyte and leucocyte are 7-12um, so the blood cell could be passed under extremely deforming the situation, and the liver cirrhosis patient's performance out of shape of blood cell is very bad, often it is unable through,ask for detentions long-term at spleen but not destroy macrophage. In liver cirrhosis and door pulse and high pressure, are destroyed by macrophages because a large number of blood cells stay in the swelling spleen, the reduced spleen function of blood cell of presenting leucocyte, erythrocyte, blood platelet etc. is hyperfunction to behave. The overbearing treatment of spleen mainly has surgeries that is excised with two kinds spleen artery thromboembolism treatments. Surgery it excises to be traditional therapeutic method, curative effect better, lose to store the intersection of blood and function and immunological function spleen while being postoperative, once the organism is infected, restive. Spleen artery thromboembolism has already kept storing the blood function and immunological function of the spleen, have solved the hyperfunction problem of the spleen function. It makes and is achieved the goal of treating because of ischemic necrosis by some spleen tissues of thromboembolism through to some spleen artery thromboembolism.
