Summary

High-frequency transvaginal sonography can detect early pregnancy abnormalities. This study observed physiologic midgut hernia in fetuses, confirming normal anterior abdominal wall development by 12 weeks gestation.

Area of Science:

  • Perinatology
  • Medical Imaging
  • Embryology

Background:

  • First-trimester ultrasound is crucial for early pregnancy assessment.
  • Transvaginal sonography provides high-resolution imaging for fetal structures.
  • Understanding normal embryonic development, like midgut herniation, is key for anomaly detection.

Purpose of the Study:

  • To evaluate the feasibility of high-frequency transvaginal sonography for scanning the anterior abdominal wall and umbilical cord insertion in the first trimester.
  • To observe the occurrence and resolution of physiologic midgut hernia between 7 and 12 weeks of gestation.
  • To assess the utility of 12-week transvaginal sonography in confirming anterior abdominal wall closure.

Main Methods:

  • A cross-sectional study involving 61 embryos and fetuses.

  • Gestational ages ranged from 7 to 12 weeks.
  • High-frequency transvaginal sonography was used to examine anterior abdominal wall, umbilical cord insertion, and midgut herniation.

    • Main Results:

    • Physiologic midgut herniation was observed in 64% of fetuses at 8 weeks, 100% at 9-10 weeks, and 25% at 11 weeks.
    • No midgut herniation was detected in fetuses at 12 weeks gestation.
    • Transvaginal sonography confirmed the complete development of the anterior abdominal wall by 12 weeks.

    Conclusions:

    • High-frequency transvaginal sonography is effective for evaluating early embryonic development, including the anterior abdominal wall and midgut.
    • The observed pattern of midgut herniation and resolution is consistent with normal embryonic development.
    • Transvaginal sonography at 12 weeks is a reliable method to confirm the closure of the anterior abdominal wall.
