Abstract Case Description3 dogs were examined because of Budd-Chiari syndrome (BCS), which is an obstruction of venous blood flow located between the liver and the junction of the caudal vena cava and right atrium. Macroscopically CT and MRI are able to depict cirrhotic changes as non-specific findings. Causes of the syndrome of the inferior vena cava The original cause of the syndrome has not yet been finally established. It can also occur during pregnancy.

The link you have selected will take you to a third-party website. Other causes include: [1] [9] [10] Prehepatic causes As noted above, problems of the liver can impact the hepatic veins and vice-versa. These veins vary in size between 6 and 15 millimeters (mm) in diameter, and theyre named after the corresponding part of the liver that they cover. The primary function of the hepatic veins is to serve as an important cog of the circulatory system.

It is usually <2cm in diameter. Early in the course of the disease, the main abnormality is enlargement of the right hepatic lobe. The obstruction of the IVC is mostly caused by a primary thrombotic event [1], either congenital or acquired. The most common cause is cirrhosis (chronic liver failure). 2. PMC Hepatic infarction results from hepatic artery disorders. . What does dilated IVC with respiratory collapse mean?
