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. It is caused most often by cirrhosis (in North America), schistosomiasis (in endemic areas), or hepatic vascular abnormalities. Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. The condition may be discovered when tests are done for other reasons. We provide pathologic evidence for hepatic arterial buffer response in non-cirrhotic patients with extrahepatic portal vein thrombosis and elucidate the histopathologic spectrum of non-cirrhotic portal vein thrombosis. Manifestations read more ) or in the intrahepatic terminal hepatic venules and hepatic sinusoids (sinusoidal obstruction syndrome Sinusoidal Obstruction Syndrome Hepatic sinusoidal obstruction syndrome is caused by endothelial injury, leading to nonthrombotic occlusion of the terminal hepatic venules and hepatic sinusoids, rather than of the hepatic read more , previously called veno-occlusive disease) but often occurs in both. Patients may be asymptomatic, or they may present only after complications occur. Plethora of inferior vena cava (IVC) - Dr. Johnson Francis, DM The liver is a dynamic vascular organ and stores 10-15% of the total human blood at any time.
