摘要
目的探讨彩色多普勒超声在诊断胎儿脐带绕颈合并心律失常中的具体作用。方法该院在2012年1—10月期间接收检查的孕妇中的500例,使用二维及彩色多普勒超声,对胎儿脐带绕颈合并心律失常进行临床诊断,在二维图像中可以直观看到胎儿的颈部有"U"、"W"或锯齿形的压迹,彩色多普勒可在胎儿的颈部检查到绕颈血流信号。对脐动脉血流的频谱节律不规则或形态异常者,使用M型超声和频谱多普勒观察胎儿心脏搏动节律、幅度情况及二尖瓣和三尖瓣口血流情况,以此来确定胎儿是否合并心律失常。结果 500例孕妇中,发现有胎儿脐带绕颈162例,其中脐带绕颈合并心律失常的42例,占整体的8.4%(42/500),产妇进行产前检查中发现胎儿宫内窘迫,在经过剖腹产之后证实。但彩超诊断胎儿脐带绕颈可产生假阳性,其原因复杂。可以有针对性地采取规避措施,进一步提高诊断准确率。结论经过临床观察治疗发现,彩色多普勒超声可以及早的发现产妇胎儿出现宫内窘迫现象,为临床观察产妇产程选择合理的分娩方式,提供了必要的依据。还能够提高产妇生产的优生率以及胎儿的生存率。
Objective To study the value of color Doppler ultrasound in the diagnosis of fetal umbilical cord around the neck with arrhythmia. Methods 500 cases of pregnant women underwent prenatal examination in our hospital from January, 2012 to October, 2012 were given two- dimensional（2D） color Doppler ultrasound for the diagnosis of fetal umbilical cord around the neck with arrhythmia. In the 2D image, the impression with the shape of ＂U ＂, ＂ W＂ or sawtooth onthe fetal neck can be seen intuitively. And the umbilical blood flow signal around the neck can be detected by color Doppler ultrasound. For fetus whose umbilical artery blood flow spectrum rhythm was irregnlar or form was abnormal, M-mode ultrasound and spectral Doppler can be used to observe the heart beat rhythm, amplitude and mitral valve and tricuspid valve opening blood flow, so as to determine whether the fetus has arrhythmia. Results Of the 500 cases of pregnant women, there were 162 cases of fetal umbilical cord around the neck, including 42 cases of fetal umbilical cord around the neck with arrhythmia, accounting for 8.4% of the whole （42/500）. Those cases with fetal distress were confirmed by cesarean section. But the diagnosis of fetal umbilical cord around the neck by color Doppler ultrasound could produce false positives, and the reasons are complex. Therefore, targeted measures can be adopted in order to increase the diagnosis rate of the disease. Conclusion It was found through clinical observation and treatment that color Doppler ultrasound can find fetal distress as early as possible, which not only provides a necessary basis for the choice of appropriate mode of delivery, but also can increase the healthy birth rate and survival rate of the fetuses.
