Background: Chronic liver disease is a heterogeneous and dynamic condition. So, noninvasive estimations of the condition and changes in portal hypertension and hepatic fibrosis are important in management of this disease. Aim of the Work: to correlate between color Doppler ultrasound findings of portal vein and severity of liver disease in cirrhotic patients with portal hypertension in the prediction of the future clinical outcomes and prognosis. Patients and Methods: This study was conducted on 50 patients attending to Al-Hussein University hospital and Damanhur Fever hospital during the time of the study who were divided into groups: Control and Child (A, B and C). Results: The study showed an increase in the mean PV diam. with P value (0.02), marked decrease in PVV with P value (0.01).and increase PV congestive index with p value (0.002). From child A to child B through child C compared with control and the difference was a statistically significant. Conclusion: Doppler ultrasound has high diagnostic value of cirrhosis. Alterations of liver hemodynamic resulting from liver cirrhosis at the tissue level are detectable on Doppler sonography. Doppler findings of direction flow and velocity of the main PV and congestive index cor‌relate with clinical parameters using Child Pugh score.
