Thinning of the hepatic veins is mostly due to compression of the hepatic lobules, which may result from fatty liver, cirrhosis and other diffuse lesions.
1. Fatty liver, when fat accumulates excessively in the liver, it leads to the development of a fatty liver, which in turn leads to compression and thinning of the hepatic veins.
2. Cirrhosis. In early cirrhosis, fibrosis of the liver leads to swelling of the liver cells and compression of the hepatic veins. In addition, the formation of pseudolobules, a hallmark of cirrhosis, can further lead to thinning of the hepatic veins.
3. Other diffuse diseases, such as parasites and hepatic stasis, can also affect the thickness of the hepatic veins, and the thinning of the hepatic veins can affect the return of blood, resulting in portal hypertension and ascites.
It is recommended to consult a doctor when the hepatic veins become thin.
