In a collective of 510 patients with uneventful pregnancies and deliveries the rate of waveform notching in the uteroplacental flow velocity pattern was examined. Notching appeared to be significantly more frequent in the uterine than arcuate artery. It was unilateral and mainly affected placenta-contralateral sites. Bilateral notching or notching on placental site were the exception. In both flow patterns notching was seen to increase as pregnancy progressed and was slightly higher in the third compared to the second trimester.
在510例妊娠及分娩过程顺利的患者群体中,对子宫胎盘血流速度模式中的波形切迹发生率进行了检查。结果显示,子宫动脉中波形切迹的出现频率明显高于弓形动脉。切迹为单侧性,主要影响胎盘对侧部位。双侧切迹或胎盘部位的切迹则较为少见。在两种血流模式中,随着妊娠进展,切迹均增多,且与孕中期相比,孕晚期的切迹略多。
