General knowledge of four department Qu _ that liver cirrhosis develops
Liver cirrhosis (liver cirrhosis) It is a kind of common chronic hepatopathy, can be caused the liver to damage by one or more reasons, the liver presents going on, filling the air, fiber pathological change.
(1) Ascites earlier stage
The liver cirrhosis patient has no ascites at this moment, have not presented the expansion and plentiful and insufficient of the systemic circulation artery either, but excessive to take a photograph of the intersection of people and the intersection of sodium and salt, can cause the intersection of ink and sodium store and stay, namely already the obstacle takes place in the renal treatment to sodium at this moment. , but the the intersection of water and sodium it held up ins to be limit since.
(2) Reactive ascites one
This renal sodium water is held up in obviously increasing and making the total blood capacity expand, then peripheral arteriectasis, in order to reduce the resistance of blood vessel. The expansion of the peripheral artery is because the viscera tissue releases a large number of various easy blood vessel materials, thus cause viscera circulating and expansion sequentially of systemic circulation. Continue it, in accordance with peripheral artery hypothesis but forming ascites.
(3) Obstinate ascites one
This patient's hepatopathy is serious, obvious sodium water retention is insensitive to diuretic treatment, the blood flow is unstable in dynamics. Renin of blood plasma - angiotensin - aldosterone system and sympathetic nervous system activity are hyperfunction, the peripheral blood vessel reduces to the active substance reactivity of blood vessel. But the renal blood vessel is highly sensitive to vasoconstrictor, and the kidney reabsorpts and further increases and arranges and secretes reducing sodium, resist the function of diuretic and favourable sodium factor.
(4) Liver kidney syndrome one
This mistake that is having obstinate ascites more compensates a liver cirrhosis patient. Hypotension appears because of further peripheral arteriectasis, the machine, as keeping circulating the capacity effectively, cause the blood vessel to shrink the material to formate and increase, especially the cover in the blood plasma is plain to increase horizontally. Because renal blood vessel, to high sensitiveness to shrink material, thus lead to the fact alternative kidney low pour into, serious sodium water held up in and renal function depleted at this moment.
