3524: Intrahepatic collateral and hemodynamic changes in chronic Budd Chiari syndrome: Doppler and echo-enhanced sonography findings

Abstract

The aim of this study is to review the morphologic findings and the hemodynamic changes in chronic Budd Chiari Syndrome (CBCS) by Doppler sonography and echo enhanced contrast agents. Although venography is the gold standard for BCS, sonography is an important imaging tool for diagnosis and follow-up. Echo-enhanced contrast agents are available and have different applications on liver studies. Mechanisms of hemodynamic compensation include increase in arterial flow, redistribution of portal flow from areas where outflow is impaired toward areas where outflow is preserved, and development of small or large venous collaterals bypassing the obstructed veins.
