Abstract
Chronic alcoholism, obesity and viral hepatitis (B & C virus) are main causes for chronic liver disease. In cirrhotic patients, portal hypertension and its complications lead to signicant morbidity and mortality. Ultrasound technique, such as duplex ultrasonography ,spectral and color Doppler imaging are the modalities of choice. Study was undertaken to evaluate spectrum of color Doppler sonographic ndings in portal hypertension, to study ow metric changes in portal hypertension and to look for presence of various Porto-systemic collaterals. Result of study shows alcoholic liver disease as the main cause for liver cirrhosis. Maximum number of patients with splenorenal collaterals. Color Doppler sonography is a valuable non-invasive alternative which provides precise information in localizing and characterizing portal vein in patients with portal hypertension and identify the presence of various Porto-systemic collaterals. The hepatic vein damping index (DI) correlates well with the severity of liver dysfunction in terms of Child Pugh score.
