Abstract:
0ne hundred and sixty-six cases with HV2 type Doppler spectrum in hepatic veins ex-amined by pulsed Doppler and the test of compressing inferior vena cava(IVC)were analysed'the re-sults showed the HV2 was mainly caused by IVC compression and secondarily the compression and nar-rowin of the hepatic veins.HV2 was found in various pathologic as wellas physiologic conditions,its presence was non-specific. Only by combining the finding of ultrasonography with the result of other cxaminations,the significance of HV2 can be explained correctly.
