Résumé
This study was designed to evaluate the role of color Doppler sonography in the assessment of portal hypertension in patients with chronic liver diseases by estimating the various hemodynamic parameters in portal and splenic veins including portal vein [PV] and splenic vein [SV] diameter, cross sectional area, flow velocity, congestion index [CI], volume flow and flow direction. These parameters were performed on 20 patients with chronic liver diseases [group I], 10 of them with esophageal varices [group IA] and 10 cases without esophageal varices [group IB]; also, 10 normal age and sex matched persons were included as a control group [group II]. The study concluded that color Doppler sonography is a good tool in evaluating the hemodynamic changes in patients with chronic liver disease as dilated portal vein and splenic vein diameter, reduced PV velocity and increased PV [CI] can be used for the detection and assessment of portal hypertension
