慢性肝脏疾患肝右静脉多普勒频谱改变

将所有受试对象分为正常对照、肝纤维化和肝硬化3组,肝硬化患者根据肝功能分为Child A、B、C三级3个亚组.用超声仪测量肝右静脉频谱.发现正常对照组100％(50/50)、肝纤维化组70.8％(34/48)、肝硬化组40.7％(55/135)的患者肝右静脉频谱为HV0型,16.7％(8/48)的肝纤维化与17.8％(24/135)的肝硬化患者肝右静脉频谱为HV1型,12.5％(6/48)的肝纤维化与41.5％(56/135)的肝硬化患者肝右静脉频谱为HV2型.肝硬化HV2型的出现率较肝纤维化患者明显升高(P<0.01).表明肝右静脉HV2型频谱的出现可作为肝硬化诊断的提示性指标.

Changes of Doppler waveforms in right hepatic vein in patients with chronic hepatic diseases

Patients were divided into normal control, liver fibrosis and liver cirrhosis groups. The patients with cirrhosis were categorized according to the Child Pugh classification into Child A,Child B and Child C groups. The waveforms of the right hepatic vein were examined with ultrasonography. HV(hepatic vein)0 waveforms were found in all the control subjects, 70.8% in those with fibrosis and 40.7% in those with cirrhosis. HV1 were found in 16.7% of those with fibrosis and 17.8% of those with cirrhosis. HV2 were found in 12.5% of those with fibrosis and 41.5% of those with cirrhosis. Statistical analysis showed that HV2 waveforms were significantly more often in patients with cirrhosis than in those with fibrosis. HV2 waveforms in the right hepatic vein are suggestive of liver cirrhosis.
