This study introduces a two-pocket amniotic fluid index (AFI) method for twin pregnancies. The twin AFI shows non-linear increases until week 27, followed by linear decreases, aiding in monitoring fetal well-being.

Area of Science:

  • Maternal-Fetal Medicine
  • Obstetrics
  • Fetal Ultrasound

Background:

  • Twin gestations present unique challenges in monitoring fetal well-being.
  • Accurate assessment of amniotic fluid volume is crucial for fetal health.
  • Existing methods for amniotic fluid index (AFI) may require adaptation for twin pregnancies.

Purpose of the Study:

  • To describe a novel methodology for calculating a two-pocket amniotic fluid index (AFI) for each fetus in twin gestations.
  • To establish normative reference ranges for twin AFI throughout gestation.
  • To assess the variability associated with the twin AFI measurement.

Main Methods:

  • A retrospective analysis of 216 pairs of two-pocket AFI measurements from twin gestations was conducted.
  • Regression analysis was used to generate curves for overall twin AFI, as well as for the larger and smaller AFI within each twin pair.

  • Intrasonographer, intersonographer, within-mother, and between-mother variations were quantified.

    • Main Results:

    • The twin AFI demonstrated a non-linear increase up to 27 weeks of gestation.
    • From 27 to 36 weeks, a decreasing linear trend was observed for the twin AFI.
    • Confidence limits were plotted for all three derived AFI curves based on variation estimates.

    Conclusions:

    • The described two-pocket AFI methodology provides a standardized approach for assessing amniotic fluid in twin pregnancies.
    • The established reference curves offer valuable insights into normal AFI progression in twins.
    • Understanding measurement variability is essential for accurate interpretation and clinical application of the twin AFI.
