FACTS ABOUT BUDD CHIARI SYNDROME

• Obstruction of the hepatic veins secondary to an obstruction of the IVC by a membrane or thrombus, or occlusion of the major hepatic vein branches (usually by thrombus) is termed BUDD CHIARI SYNDROME .
•  In most patients there is relative preservation of the caudate lobe, which usually drains via separate veins directly into the IVC inferior to the normal hepatic venous confluence.
• US, particularly with the aid of colour and spectral Doppler techniques, can lead to an unequivocal diagnosis in acute BCS by identifying the presence of thrombus in major veins.
•   US demonstrate abnormal collateral veins passing between the major hepatic veins, or continuous reversal of flow in a main hepatic vein. 
• The inability to demonstrate any hepatic veins or related flow is highly suspicious but this should be interpreted with caution in the presence of cirrhosis.
• On angiography the venographic appearances are characteristic and are said to resemble a spider's web
