Umbilical vein blood flow was measured using a combination of real-time and pulsed Doppler ultrasonic equipment in 11 pregnancies associated with chronic fetal hypoxia. All the results obtained during the last 12 h before delivery demonstrated pathologically low flow values, mainly due to constriction of the umbilical vein.
在11例伴有慢性胎儿缺氧的妊娠中,使用实时和脉冲多普勒超声设备组合测量脐静脉血流。分娩前最后12小时获得的所有结果均显示血流值病理性降低,主要原因是脐静脉收缩。
