摘　　要：目的　探讨胎儿肝静脉的多普勒血流频谱及其临床意义。方法　 112例孕妇 (孕龄 2 7～ 42周 )行常规超声检查后 ,对胎儿肝中静脉再行二维超声及多普勒超声检查。结果　正常胎儿肝静脉多普勒血流频谱分为三型。Ⅰ型 6 8例 ,表现为二个负向波 ,占 6 0 .7%。Ⅱ型 2 3例 ,表现为三相波即二个负向波一个短暂正向波 ,与正常成人一致 ,占 2 1.6 %。Ⅲ型 2 1例 ,表现为一个负向波 ,占 18.7%。 2例胎儿肝静脉血流频谱出现异常 ,其正向血流明显增高 ,经尸检证实为先心病。结论　多普勒超声探测胎儿肝静脉血流频谱是完全可行的 ,其正向血流增高增多可为临床诊断胎儿某些先心病提供重要依据。Objective To study the Doppler flow spectrum of fetal hepatic vein.Methods One hundred and twelve pregnant women of gestational age 27～42 weeks were examined by common ultrasonography, then the vein of fetal liver were investigated by two dimensional and duplex Doppler ultrasonography. Results The Doppler flow spectrum of normal fetal hepatic vein could be classified into 3 types:Type I, 68 cases,showed two negative waveforms.Type Ⅱ, 23 cases showed 3 phase waveform, two negative and one transient positive waves,in accordance with those of adult. Type Ⅲ, 21 cases, showed one negative waveform.Of all the spectra, two cases were abnormal, showing markedly increased positive flow, which was proved to be due to congenital heart disease.Conclusions Investigating the fetal hepatic venous flow by duplex Doppler ultrosongraphy was feasible.The Doppler flow spectrum showed that the increase in the frequence and amplitude of positive flow spectrum could be important to the diagnosis of the congenital heart disease.
