First trimester ultrasonographic evidence of FHM infers a good prognosis for normal pregnancies, although similar data in RSA is scarce. Abortion before 20 weeks' gestation occurred in 12 of 167 control patients (7.2%) and five of 23 patients with RSA (21.7%) after detection of fetal heart motion (P = 0.0382). The abortion rate decreased with a MSS-CRL difference of > 8 mm in controls but not in patients with RSA. We conclude that the probability of pregnancy success is not improved with FHM identification in patients with RSA.
孕早期超声检查显示FHM提示正常妊娠预后良好，尽管复发性流产（RSA）方面的类似数据较少。在检测到胎心搏动后，167例对照患者中有12例（7.2%）在妊娠20周前流产，23例RSA患者中有5例（21.7%）流产（P = 0.0382）。在对照患者中，当平均孕囊直径（MSS）-头臀长（CRL）差值> 8 mm时流产率降低，但RSA患者中并非如此。我们得出结论，RSA患者通过识别FHM并不能提高妊娠成功的概率。
