Check _'s general knowledge in Ultrasonography B of the liver cirrhosis patient
B superenergic to measure the diversified, many angle to the intersection of liver and essence, the intersection of liver and artery, the intersection of liver and intravenous, portal vein, spleen and other internal organs, diagnose value higher to cirrhosis and portal vein hyperbarism. Ultrasonography B is checked, unusually changed at the time of liver cirrhosis, mainly have the following several respect:
First, all kinds of shape of liver and echo change: It is swelling that liver cirrhosis can be seen the liver in early days, the essence echo is dense, strengthens or increases thickly; Liver dwindle later period, it is full of bumps and holes for liver to behave, take the form of tubercle form, cockscomb structure, step change and abnormality wither out of shape, the filling the air echo is strengthened, is distributed irregularity. Embodied in the left, right leaf of liver to diminish directly from head to foot, the liver becomes thin, the left leaf of liver shrinks often more prominent, but there is liver left leaf compensating increase of a few patients; Liver make membrane increase thick losing smooth the intersection of fiber and on line, the echo is strengthened, the thickness is uneven, especially dirty one of surface of liver is full of bumps and holes, can take the form of sawtooth, clearer when present the ascites, or abnormality that the edge angle of liver is dull; The liver essence echo is strengthened, present intensive medium and small luminous points or thick luminous points, echo uneven, it is obvious irregular strong the intersection of echo and pieces of Suo, patch echo, can see the small low echo district in the high echo district.
Second, the blood vessel behaves in the liver: Thickness irregularity, the blood vessel is twisted, stopped up and can't seen, it is obvious with the liver vein particularly, its backbone is attenuated, the branch is narrow. The portal vein is propped up and propped up the arrow department to increase thickly on the left because of the blockage backbone of the blood flow, right, ,the intersection of portal vein and the intersection of backbone and internal diameter> 13mm, the intersection of door and the intersection of pulse and right prop up, greater than 10mm, left prop up greater than llmm, spleen intravenous internal diameter loud to 8mm, brief on the high pressure of portal vein. With and ascites that the spleen is swelling more, the thickness exceeds 4cm at the time of splenomegaly, the length is big in 120cm; It is that the banding does not have echo district that Ultrasonography B downs the ascites, and a small amount of ascites can reveal, and clinical and difficult to find to have at this moment.
Third, gallbladder can dwindle, have, shift backward with liver, a common one whether the gallbladder wall increases thick or one pair of signs of wall most, there are low echoes in the two -storey echo strips.
