Out of 255 patients with threatened abortion 67 gave a regular menstrual history and at ultrasound examination had a live fetus with a crown-rump length (CRL) of 10-65 mm, equivalent to a gestational age of 7-13 weeks. The CRL of these fetuses was smaller than expected from their menstrual age (P less than 0.01). For this phenomenon we suggest the term early fetal growth delay. Seven patients aborted and one experienced intrauterine fetal death. These eight fetuses had on average smaller CRL than the remainder 59 fetuses (P less than 0.05). Fetal growth delay may therefore be considered a risk factor in threatened abortion.
在255例先兆流产患者中，67例月经史规律，超声检查显示有存活胎儿，头臀长（CRL）为10 - 65毫米，相当于孕龄7 - 13周。这些胎儿的头臀长小于根据其月经龄预期的长度（P < 0.01）。对于这种现象，我们建议使用“早期胎儿生长迟缓”这一术语。7例患者流产，1例发生宫内胎儿死亡。这8例胎儿的头臀长平均小于其余59例胎儿（P < 0.05）。因此，胎儿生长迟缓可能被视为先兆流产的一个危险因素。
