This retrospective study evaluates early first trimester FHR, gestational SACD, and CRL measurements as means to predict ultimate pregnancy outcome. Outcomes of 274 pregnancies were monitored a single time by transvaginal ultrasonography with measurements recorded between 5.0 and 9.0 weeks' gestation. The measurements were then correlated with the pregnancy outcomes. FHR (P < 0.0001), gestational SACD (P = 0.0002), and CRL (P = 0.0059) each correlated positively with a successful pregnancy outcome. Measurements from a single transvaginal ultrasonogram can be used to predict a successful pregnancy outcome in the early first trimester.
这项回顾性研究评估孕早期首阶段的胎心率（FHR）、妊娠期间的子宫动脉血流动力学指标（SACD）以及头臀长（CRL）测量值，以此作为预测最终妊娠结局的手段。通过经阴道超声对274例妊娠的结局进行单次监测，记录妊娠5.0至9.0周之间的测量值。然后将这些测量值与妊娠结局进行关联分析。胎心率（P < 0.0001）、妊娠期间的子宫动脉血流动力学指标（P = 0.0002）和头臀长（P = 0.0059）均与成功妊娠结局呈正相关。单次经阴道超声检查的测量值可用于预测孕早期首阶段的成功妊娠结局。
