Fetal brain was retrospectively evaluated in 418 normal fetuses at 16–28 weeks of gestation. The multiplanar mode to obtain the axial cerebral plane and measured the width of the cavum septum pellucidum (CSP) and biparietal diameter (BD). All measurements of CSP were done from as the widest diameter across both borders in an inter-to inter fashion. The CSP width is increasing at second trimester of gestation. Normal range plotted on the reference range (mean, 5th and 95th percentiles) of fetal width CSP by measuring of its size may be useful for assessment of fetal brain development in the second trimester of gestation.

Introduction: Newer research has highlighted significant neurological impairments in children and adults with congenital heart disease (CHD). The more severe the heart defect, the higher the neurologic impairment. Pregnancies complicated by fetal or maternal CHD carry a higher risk of placental abnormalities. We studied the association between pregnancy hormonal levels and fetal head and body growth. Hypothesis: Placental dysfunction in pregnancies with fetal or maternal CHD alters pregnancy hormonal levels affecting fetal brain and somatic growth. Methods: We performed a retrospective case-control study on pregnant women (year 2010-2019) at the University of Iowa. Only women with first and/or second trimester prenatal screening (ultrasound and blood test) were included. Pregnancies with fetal chromosomal abnormalities, multiple gestation, maternal diabetes, smoking, or hypertension were excluded. Pregnancies were either healthy controls (n=36), women with CHD (MCHD; n=26), or fetus with CHD (FCHD; n=23). Pregnancy hormonal levels, ultrasound findings, and fetal/neonatal growth percentiles and/or z-scores data were analyzed. Results: Women with CHD were younger (p=0.004) with increased fetal nuchal translucency (p=0.003) compared to controls. Women in MCHD (p=0.02) and FCHD (p=0.02) group delivered earlier than controls. FCHD had significantly lower pregnancy associated plasma protein-A (PAPP-A) levels than controls (p=0.04). The groups had no difference in the second trimester fetal head circumference (HC) and femur length. FCHD group had significantly smaller HC percentile (p=0.03) and z-scores (p=0.03) at birth than controls. Both FCHD and MCHD had smaller birth weight and length compared to controls. However, only FCHD group demonstrated significantly lower HC to birth weight ratio (p=0.01). The controls had a positive correlation between human chorionic gonadotropin level and head circumference z-score at birth (r=0.34;p=0.053). Conclusions: Pregnant women with CHD have increased fetal nuchal translucency and deliver at earlier gestational age. Women with fetal CHD have smaller neonatal head and body size at birth with associated low PAPP-A level early in their pregnancy probably related to placental dysfunction.

ABSTRACT In the last 20 years, the role of first-trimester ultrasound screening has expanded from individual calculation of the risk of aneuploidy through measurement of the nuchal translucency to a powerful technique to evaluate important aspects of the fetal anatomy. Traditionally, the full anatomy scan for detection of structural anomalies has been performed in the second trimester of pregnancy. However, with the implementation of the first-trimester scan at 11 to 13 weeks of gestation many of the structural anomalies traditionally detected in the second trimester can now be identified earlier in pregnancy. In the first part of this review we discuss the main ultrasound findings that may facilitate the prenatal detection of fetal brain, face and neck abnormalities in the first trimester of pregnancy.
