    Abstract:
    The portal vein (PV) velocity was measured by duplex Doppler ultrasound to predict the severity of portal hypertension. A total of 143 patients with liver cirrhosis were studied from January 1991 to June 1992. There were 104 males and 39 females with a mean age of 52 years old (range 23-76). The maximal PV velocity was significantly lower in patients with moderate and severe varices, cardiac varices, red-color signs on varix, esophagitis and congestive gastropathy. The patients with bleeding esophageal varices or upper gastrointestinal tract were found to have a significantly maximal PV velocity. Comparing patients without ascites or victims with controllable ascites. The maximal PV velocity in Child's C or mortality cases was also significantly lower than that in Child's A, Child's B and surviving cases. If we set the cut off value of PV velocity at 15 cm/sec, we could get the accuracy of 67.8%, 62.2%, 67.8% and 73.5% in the prediction of massive ascites, varices severity, Child C class and mortality respectively. In conclusion, PV velocity may reflect the severity of clinical portal hypertension in cirrhotic patients; it could be a prognostic factor in cirrhotic patients.
