摘要
目的探讨彩色多普勒超声联合声辐射力脉冲成像(ARFI)对菊叶三七致肝小静脉闭塞病(HVOD)的诊断价值。方法应用彩色多普勒超声和ARFI技术分别对30例健康志愿者(正常对照组)和29例HVOD患者(HVOD组)进行检查,分析HVOD的超声特征。比较两组门静脉、脾静脉、肝静脉内径、最大流速及频谱形态,以及肝、脾剪切波速度(SWV)。结果 HVOD组肝脏呈"斑片状"改变25例(86.0%),脾脏大小正常23例(80.0%),门静脉频谱形态异常26例(89.6%),肝静脉频谱形态异常17例(58.6%);两组门静脉、脾静脉内径比较差异无统计学意义;HVOD组门静脉和脾静脉流速,以及肝静脉内径和流速均明显低于正常对照组,肝、脾SWV值均明显高于正常对照组,差异均有统计学意义(均P<0.05)。结论彩色多普勒超声联合ARFI为菊叶三七致HVOD提供了更加丰富的诊断依据,具有重要的诊断价值。
Objective To explore the value of acoustic radiation force impulse（ARFI） imaging and color Doppler ultrasonography on evaluating the effect of hepatic veno-occlusive disease（HVOD）after taking Gynura segetum.Methods The shear wave velocity（SWV）of liver and spleen were measured using ARFI imaging in 30 healthy volunteers（control group）and 29 patients of HVOD（HVOD group）. Portal vein,right hepatic vein and splenic vein were evaluated by color Doppler ultrasonography,diameters and maximum velocities were measured and compared. Results The liver in HVOD group was＂patchy＂change in 25 cases（86.0%）,spleen size was normal in 23 cases（80.0%）,26 cases（89.6%）of abnormal portal vein,spectrum morphology of 17 cases of abnormal hepatic vein waveform（58.6%）,the differences of portal vein and splenic vein diameter between control group and HVOD group had no statistical significance. Portal vein,splenic vein,hepatic vein diameter and blood flow velocity were decreased compared with control group,the differences were statistically significant（all P0.05）.SWV values of liver and spleen in HVOD group were significantly higher than control group,the differences were statistically significant（P 0.01）. Conclusion Color Doppler ultrasonography combined with ARFI have a higher value in clinical application for noninvasive diagnosis of HVOD.
