Abstract

Objective Several studies have previously assessed the value of changes in the fetal adrenal gland to predict preterm labor. The aim of this study is to evaluate the correlation between fetal adrenal gland measurements after 36 weeks and obstetrical outcomes.

Methods Abdominal two-dimensional (2D) ultrasound is used to measure in the transversal plane the length of fetal zone (D1), the width (D2), and the length (D3) of fetal adrenal gland, and, subsequently, the fetal zone enlargement (FZE), in 98 primigravida women after 36 weeks. Labor and delivery outcomes were assessed and compared with these measurements.

Results FZE changes had no association with spontaneous onset of labor. No association was found between all adrenal gland measurements and delivery onset. There was a significant relationship between D1, D2, and D3 and the delivery method. Patients delivered by cesarean section had smaller fetal adrenal gland dimensions, defining D1= 0.16 cm, D2 = 0.7 cm, and D3 = 2.37 cm as cutoff levels based on receiver operator characteristics curves.

Conclusion The 2D measurement of the fetal adrenal gland after 36 weeks seems to predict the delivery method in low-risk primigravida women.

Key Points

  • We evaluate fetal adrenal gland measurements after 36 weeks versus the obstetrical outcome.

  • No association was found between all adrenal gland measurements and delivery onset.

  • Patients delivered by cesarean section had smaller fetal adrenal gland dimensions.

Keywords

Adrenal - Fetal - Fetal zone enlargement - Mode of delivery - Ultrasound

Synopsis

Fetal adrenal gland dimensions in the 9th month are not correlated to the spontaneous onset of labor but may be associated with the mode of delivery.
