The aim of this study is to assess whether early cervical lymphatic obstruction is associated with a sonographically detectable dilatation of the ventricular system in the 1st trimester of pregnancy. In particular, the objective is to assess whether fetuses with non-immune hydrops fetalis (NIHF), cystic hygroma, or enlarged nuchal translucency (NT) have a greater atrial width/biparietal diameter (AW/BPD) ratio than normal at time of the combined first trimester screening scan. This retrospective study included 96 first trimester fetuses (33 normal and 63 with various degree of cervical lymphatic engorgement). Inclusion criteria were CRL in the 45-84 mm range and availability of one or more three-dimensional volume datasets of the fetal head, acquired from the BPD plane. Each three-dimensional volume dataset was opened and multiplanar correlation employed to align the three orthogonal planes. The ratio between the atrial width and the BPD (AW/BPD ratio) was used to evaluate the possible presence of increased amount of cerebrospinal fluid. Abnormal cases were placed into 4 categories: 1)enlarged non-septated NT 2.5-3.9 mm, no hydrops; 2) grossly enlarged non-septated NT/ edema >3.9 mm; 3) cystic hygroma and/or NIHF; 4) major anomalies with NT <2.5 mm. Presence of dilatation of the latero-cervical jugular lymphatic sacs, karyotype and presence of congenital anomalies were also recorded. The One-way ANOVA test was used to compare means. Intra- and inter-observer variability were also assessed. The AW/BPD ratio was found to be significantly higher in fetuses with grossly enlarged NT/nuchal edema and NIHF/septated cystic hygroma than in normal (p <0.05 and p <0.01, respectively). Also, the AW/BPD ratio was significantly higher in NIHF/septated cystic hygroma than in enlarged NT 2.5-3.9 mm (p <0.05). In case of enlarged NT (2.5-3.9 mm), the AW/BPD ratio is significantly higher in presence of JLS (p <0.01). At the end of the first trimester, presence of cervical lymphatic engorgement, in terms of grossly enlarged NT, nuchaledema, septated cystic hygroma, and NIHF, is statistically associated with a moderate dilatation of the ventricular system. Of note, among fetuses with moderately enlarged NT, those with evidence of dilatation of the JLS show a statistically significant increase in the AW/BPD ratio.

Abstract Background This case report is to show the details of the face of a very rare ethmocephaly at 14 weeks of gestation. Case presentation After the regular transabdominal two-dimensional (2D) scan for nuchal translucency we could describe the following malformations: holoprosencephaly, proboscis and an abnormal face, omphalocele containing bowel, hyperechoic kidneys and megacystis. In addition, we acquired transvaginal three-dimensional (3D) ultrasound volume blocks of the fetal head, scanned with different insonation angles and stored them for later analysis. Using the multiplanar mode the volume blocks taken from the front show all details of the face: proboscis, hypotelorism, microphthalmia, cleft palate, accelerated development of the frontal bones and premature closure of the metopic suture. The volume blocks taken through the squamosal suture show all details of the fossa posterior and brain: fused thalami surrounded by the typical monoventricle, normal brain stem, elongation of anterior membranous area. Render mode shows a precise 3D image of the face. To better demonstrate the changes of the fetal face a post-mortem photo of the fetal face is included. Conclusion This case report can demonstarte the typical changes of ethmocephaly in the first trimester using transvaginal 3D scan.

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.

AbstractDiastrophic dysplasia is a rare genetic disorder characterized by short limbs and deformities of several joints occurring in conjunction with xyphoscoliosis, distinctive abduction of the first metacarpals (hitchhiker thumbs). A 28-year-old pregnant patient was referred due to detection of increased nuchal translucency at the first-trimester scan. We describe a case of diastrophic dysplasia diagnosed by two- and three-dimensional ultrasound and termination of pregnancy at 13 weeks of gestation. This case is the first report in the literature in which 3D ultrasound was used in diagnosis of diastrophic dysplasia as early as the 13th week of pregnancy. We think that prenatal diagnosis of diastrophic dysplasia can be possible even at first trimester.
