Ultrasound examination of a 30-week fetus, appropriate for gestational age, revealed a nuchal cord and absence of end-diastolic velocities in the Doppler waveforms of the umbilical artery. Cardiotocography suggested impending fetal distress, clinically confirmed following expedient abdominal delivery. We suggest that Doppler velocimetry of the umbilical vessels may be useful in the assessment of viable fetuses with a sonographic diagnosis of a nuchal cord. Conversely, a nuchal cord should be considered as part of the differential diagnosis of abnormal Doppler velocimetry of the umbilical vessels.
对一名孕30周、孕周相符的胎儿进行超声检查，发现有脐带绕颈，且脐动脉多普勒波形中舒张末期血流速度消失。胎心监护提示即将发生胎儿窘迫，急诊剖宫产术后临床得到证实。我们认为，脐血管多普勒测速可能有助于评估超声诊断为脐带绕颈的存活胎儿。相反，脐带绕颈应被视为脐血管多普勒测速异常鉴别诊断的一部分。
