Summary

Embryonal growth delay in early pregnancy, measured by crown-rump length, significantly increases spontaneous abortion risk. Accurate gestational age assessment via ultrasound is crucial for optimal obstetric care and fetal outcomes.

Area of Science:

  • Obstetrics and Gynecology
  • Prenatal Diagnostics
  • Reproductive Medicine

Background:

  • Accurate determination of gestational age is fundamental in obstetric care.
  • First-trimester ultrasound measurements are critical for assessing pregnancy progression.
  • Embryonal growth patterns can indicate potential pregnancy complications.

Purpose of the Study:

  • To investigate the relationship between embryonal growth delay and the risk of spontaneous abortion.
  • To evaluate the accuracy of crown-rump length (CRL) measurements for gestational age determination.
  • To highlight the clinical significance of early pregnancy ultrasound findings.

Main Methods:

  • Prospective collection of clinical and ultrasound data from 403 first-trimester pregnancies.

  • Correlation analysis between crown-rump length (CRL) and gestational age based on amenorrhea duration.
  • Comparison of spontaneous abortion rates between pregnancies with and without significant embryonal growth delay.

    • Main Results:

    • A significant association was found between embryonal growth delay (≥7 days lag in CRL) and an increased risk of spontaneous abortion (16% vs. 5.0%, p<0.01).
    • Approximately 22.7% of women with regular menstrual cycles exhibited a significant embryonal growth delay.
    • CRL measurements provide a more accurate assessment of gestational age compared to amenorrhea alone.

    Conclusions:

    • Crown-rump length (CRL) measurement is essential for accurate gestational age assessment in early pregnancy.
    • Embryonal growth delay identified by CRL is a significant predictor of spontaneous abortion risk.
    • Precise gestational dating is critical for managing pregnancy and preventing adverse outcomes.
