What does liver cirrhosis B-ultrasound show?
Cirrhosis is a common chronic liver disease, and B-ultrasound examination is one of the important means for its diagnosis and monitoring. This article will combine the hot topics and hot content on the Internet in the past 10 days, introduce the performance of liver cirrhosis in B-ultrasound examination in detail, and use structured data to help readers better understand.
1. B-ultrasound manifestations of liver cirrhosis
B-ultrasound examination can show the shape, structure and blood flow of the liver through sonograms. The following are common manifestations of liver cirrhosis in B-ultrasound:
| B-ultrasound performance | Detailed description |
|---|---|
| Changes in liver morphology | The surface of the liver is not smooth and appears nodular or wavy; the liver may shrink or increase in size. |
| Increased echogenicity of liver parenchyma | The intrahepatic echoes are uneven and granular or patchy, suggesting fibrosis. |
| signs of portal hypertension | The diameter of the portal vein is widened (>13 mm), the spleen is enlarged, and may be accompanied by ascites. |
| Hemodynamic changes | Hepatic artery blood flow increases, portal vein blood flow slows down, and collateral circulation may occur. |
2. Clinical significance of B-ultrasound examination
B-ultrasound examination plays an important role in the diagnosis and monitoring of liver cirrhosis:
1.early screening: B-ultrasound can detect early changes in liver morphology and structure and help identify patients with potential cirrhosis.
2.condition assessment: Evaluate the severity of liver cirrhosis by observing indicators such as liver echo and portal vein width.
3.Complication monitoring: B-ultrasound can promptly detect complications such as ascites, splenomegaly, and portal vein thrombosis.
4.Treatment follow-up: Regular B-ultrasound examinations can monitor treatment effects and disease progression.
3. B-ultrasound grading standards for liver cirrhosis
According to B-ultrasound performance, liver cirrhosis is usually divided into the following three grades:
| Grading | B-ultrasound performance | clinical significance |
|---|---|---|
| Mild | The echo of the liver is slightly thickened and the surface is slightly uneven. | Early cirrhosis, well compensated liver function |
| Moderate | The liver is significantly shrunken, the surface is nodular, and the portal vein is widened | Liver function begins to decompensate |
| Severe | The liver was significantly shrunk, ascites was evident, and collateral circulation was extensive | Severe decompensation of liver function |
4. Precautions for B-ultrasound examination
1.Preparation before inspection: It is usually necessary to fast for more than 8 hours to reduce intestinal gas interference.
2.Check posture: Generally, the supine position is used. If necessary, it is necessary to lie on the side to cooperate with breathing.
3.Check timing: For patients with liver cirrhosis, it is recommended to review the B-ultrasound every 3-6 months.
4.Interpretation of results: B-ultrasound results should be comprehensively judged in conjunction with clinical symptoms and other tests (such as liver function, FibroScan, etc.).
5. Comparison of B-ultrasound and other examinations for liver cirrhosis
| Check method | Advantages | limitations |
|---|---|---|
| B-ultrasound | Non-invasive, convenient, economical and repeatable | The detection rate of early liver cirrhosis is low |
| CT/MRI | High resolution allows assessment of liver volume | High cost and radiation (CT) |
| FibroScan | Quantifiable liver stiffness | Affected by ascites and obesity |
| liver biopsy | diagnostic gold standard | Invasive, sampling error |
6. Prevention and management of liver cirrhosis
1.Cause treatment: Treat primary diseases such as viral hepatitis and alcoholic liver disease.
2.Regular monitoring: Patients with liver cirrhosis should undergo B-ultrasound and other related examinations regularly.
3.lifestyle intervention: Stop drinking, eat a low-salt diet, exercise moderately, and avoid hepatotoxic drugs.
4.Complication prevention: If necessary, use drugs to prevent complications such as esophageal and gastric variceal bleeding.
Summary: B-ultrasound is an important tool for the diagnosis and management of liver cirrhosis, which can visually display the morphological and structural changes of the liver. Combined with clinical manifestations and other examinations, B-ultrasound can provide important basis for early detection, condition assessment and treatment follow-up of cirrhosis. Patients should follow the doctor's instructions for regular check-ups to detect changes in their condition in a timely manner.
