AI Article Synopsis

  • Research on fetal arterial structure and function is scarce, prompting this study to investigate the abdominal aorta of fetuses at 24-25 weeks gestation.
  • The study compared measurements of intima-media thickness, compliance, and distensibility between fetuses of diabetic (DM) and non-diabetic mothers (NDM), finding no significant differences in IMT or distensibility.
  • However, fetal abdominal aortic compliance was significantly greater in the DM group compared to the NDM group, highlighting the feasibility and potential benefit of measuring fetal abdominal aorta characteristics.

Article Abstract

Research describing fetal arterial structure and function is lacking within the literature. This study's purpose was to measure intima-media thickness (IMT), compliance and distensibility of 24- to 25-week fetuses' abdominal aortas using conventional ultrasonography from 16 diabetic (DM) and 25 non-diabetic mothers (NDM). We found no significant differences in fetal abdominal aorta IMT (P = .68), diameter distensibility (P = .22), or cross-sectional distensibility (P = .23). However, both fetal abdominal aortic diameter compliance (P = .03) and cross-sectional compliance (P = .005) were greater in DM than in NDM (P = .005). This study demonstrates that it is possible and potentially useful to measure fetal abdominal aorta biometrics and biomechanical characteristics.
