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.
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.
59例患有弥漫性肝脏病变的患者和28名健康个体接受了肝静脉循环的双功超声检查。观察到三种时间速度频谱，随后分为三组：1. 正常（三相）频谱。2. 振幅降低和变形。3. 平坦血流频谱。
对照组无一例外符合1型正常（三相）频谱。2型可见于脂肪变性、慢性活动性肝炎和肝硬化。3型频谱在肝硬化中显著出现，敏感性为71%，特异性为100%。将结果与在主门静脉中测量的循环速度进行比较，敏感性为88%，特异性为94%。基于这一初步经验，作者认为技术上简单的肝静脉多普勒超声检查可以在弥漫性肝脏病变病例中为临床分析提供重要的额外信息，从而完善临床分析。
