| 目的 分析先天性心脏病(CHD)胎儿静脉导管的频谱特征及血流参数,探讨其血流参数的变化及特定CHD与参数之间的可能相关性。方法 记录160胎CHD胎儿静脉导管波形及各频谱参数,随访并分组,探寻可能对CHD有提示意义的血流参数。结果 160 胎CHD胎儿中,右心系统发育异常胎儿的静脉导管频谱异常发生率明显高于其他畸形,其中又以三尖瓣闭锁+室间隔缺损及室间隔完整的右心室流出道梗阻畸形者发生率更高;且当搏动指数>1.39、前负荷指数>1.35及静脉峰值流速指数>1.53时,诊断右心系统发育异常的意义较大。结论 静脉导管波形异常可早期提示胎儿CHD,尤其是右心系统发育不良,对临床决策及判断预后有一定指导意义。 |

| Objective To analyze the flow spectral characteristics and parameters of ductus venosus (DV) of congenital heart disease (CHD) fetuses, in order to find out the relationship between different CHD and DV waveform characteristics. Methods DV waveform and spectrum parameters of fetuses with CHD were recorded and followed up. Parameters for CHD indication were analyzed. Results In 160 fetuses with CHD, the incidence of abnormal waveform in the right heart system defect fetuses was significantly higher than in other fetuses, especially in fetuses with tricuspid atresia ＋ ventricular septal defect and right ventricular outflow tract obstruction malformations associated with intact ventricular septum. And Pulsatility index for veins >1.39, preload index >1.35 and peak velocity index for veins >1.53 had important significance in diagnosis of right heart system defect. Conclusion The incidence of abnormal waveform is significantly higher in CHD fetuses, especially in fetuses with right heart system defect. Abnormal waveform of DV can give some guidance to clinical decision and prognosis evaluation. |
