Esophageal Varices develops by the changes in portal hemodynamics. So, characterizing both the qualitative and quantitative changes in hemodynamics in the portal system is important in patients with Esophageal Variceal Bleeding caused by liver cirrhosis. We undertook this study to investigate the discriminant for estimate of esophageal variceal bleeding by significant Doppler parameters. The purpose of our study was to evaluate the significant Doppler parameters in patients with cirrhosis and to make a discriminant for estimate of esophageal variceal bleeding, and to predict the dangers of bleeding. Significant differences were found in main portal vein diameter(MPVD), MPV velocity max(MPV Vmax), blood flow rate of MPV and spleen vein, MPV congestion index(MPVCI), Right Portal Vein Vmax(RPVVmax), reflux of MPV, flat pattern of MPV between control group, none of varices group, EVB positive group and EVB negative group. MPVD, MPVVmax in EVB(+) group were significantly higher than in EVB(-) group(P<0.01). Any significant differences were not found in SV:MPV blood flow ratio between control goup and no varices group. Significant differences were found in MPVCI, RPVVmax between no varices group and EVB(-) group, EVB(+) group and EVB(+) group. MPVCI in EVB(+) group were higher than the EVB(-) group(p<0.05) and RPVVmax in EVB(+) group were lower than EVB(-) group. We had found the significant color and impulse Doppler parameters to evaluate the esophageal varices and predicted danger of esophageal variceal bleeding by discriminant. In the patient with portal hypertension caused by cirrhosis significant Doppler parameters for evaluation of esophageal varices were MPVD, MPVVmax, CI, SV/MPV, RPVVmax, reflux of MPV, flat pattern of EVB. We made discriminant by 7 parameters and predicted dangers of EVB. Reliability of discriminant was 90% and 91.2% respectively in EVB positive group, EVB negative group.
