59 patients suffering from diffuse liver lesion and 28 healthy individuals had undergone duplex ultrasound examination of the hepatic vein circulation. Three time-velocity spectra had been noticed and later divided into three groups: 1. Normal (triphasic) spectrum. 2. Decreased and deformed amplitudes. 3. Flat flow spectrum. Results: The control group matched the normal (triphasic) spectrum of type 1 without exception. Type 2 could be observed in steatosis, chronic active hepatitis and cirrhosis alike. The type 3 spectrum was shown significantly, to occur with 71% sensitivity and with 100% specificity in cirrhosis of the liver. The comparison of the results with the circulation velocities measured in the main portal vein showed a sensitivity of 88% and a specificity of 94%. Based on this initial experience, authors hold the view that a technically simple hepatic vein Doppler-sonography can complete the clinical analysis with significant additional information in cases of diffuse liver lesion.
