Background : Esophageal varices are the most dangerous
complication of the portal hypertension which occurs as a
result of increased hydrostatic pressure within the portal
vein. Actual direct measurement of portal pressures is an
invasive technique while Doppler ultrasound and MDCT are
non-invasive, relatively cheap and easily accessible imaging
modality that helps easily detection of esophageal varices. It
also provides useful information as to it’s cause and presence
of complications. The present study was carried out to study
the usefulness of portal vein Doppler and MDCT in Portal
hypertension due to liver cirrhosis. 50 cases of clinically
proven or suspected cases of esophageal varices were
assessed with Doppler ultrasound and MDCT. Retrospective
review of the findings was done to assess the status of Portal
vein and hepatic artery for calibre, presence or absence of
blood flow, direction of flow, velocity. Presence of
esophageal varices .
Result: there is significant association between the decrease
in the peak portal venous velocity, portal venous flow , portal
vein congestion index and increase hepatic artery resistivity
index and the increase in the esophageal varices grading in
MDCT and in endoscopy. There is significant association
between the grading of the esophageal varices in CT and its
grading at endoscopy
