Abstract
|
|
|
Purpose: To evaluate the diagnostic value of duplex Doppler sonography(US) in the detection of cirrhosis in patients with chronic hepatitis B.
Materials & Methods: Over a recent 14-month period, 50 patients with chronic hepatitis B and 50 control subjects were prospectively evaluated with duplex Doppler US. Doppler spectral waveforms were obtained from right hepatic vein with optimized
methods.
Results: Waveforms of hepatic veins were normal in all control subjects. Abnormal waveforms of hepatic veins showed a sensitivity of 72%, specificity of 88%, positive predictive value of 86%, negative predictive value of 76%, and diagnostic
accuracy of
80% in the detection of cirrhosis in patients with chronic hepatitis B.
Conclusion: Duplex Doppler US of hepatic veins could be a promising adjunction tool in detecting the hepatic cirrhosis in patients with well-compensated chronic hepatitis B.
