A Prospective Study

Background: To determine whether there is an additional value of virtual embryoscopy with 3Dimensional (3D) ultrasound above (2D) ultrasound regarding detection rates of structural abnormalities in first trimester pregnancy.Methods: This was a prospective study consisting of 52 pregnant women with gestational age ranging from 6 to 12 weeks. 2D and 3D ultrasound scan was performed using GE voluson E8 transvaginal probe. All scans were evaluated by ten gynecologists trained in USG. The observations were noted and compared for anatomical details and detection of structural defects.Results: It was found that images were seen well with 3D (virtual embryoscope). i.e. maximum count 19 in the table and there is statistically significant difference between 3D and 2D images with a p-value <0.01 at 95% confidence interval (CI).Conclusions: Virtual embryoscope is an innovative tool for evaluation of developing embryo and early foetal morphology. The advantages are the ability to reconstruct 3D images with the stored scanned volume and examine without having to rescan the patient.

<b><i>Objective:</i></b> The objective of this study was to assess the position of the conus medullaris (CM) at the first trimester 3D ultrasound in a cohort of structurally normal fetuses. <b><i>Methods:</i></b> This was a multicenter prospective study involving a consecutive series of structurally normal fetuses between 11 and 13 weeks of gestation (CRL between 45 and 84 mm). All fetuses were submitted to 3D transvaginal ultrasound using a sagittal view of the spine as the starting plane of acquisition. At offline analysis, the position of the CM was evaluated by 2 independent operators with a quantitative and a qualitative method: (1) the distance between the most caudal part of the CM and the distal end of the coccyx (CMCd) was measured; (2) a line perpendicular to the fetal spine joining the tip of the CM to the anterior abdominal wall was traced to determine the level of this line in relation to the umbilical cord insertion (conus to abdomen line, CAL). Interobserver agreement for the CCMd was evaluated. Linear regression analysis was used to determine the association between the CMCd and CRL, and a normal range was computed based on the best-fit model. The absence of congenital anomalies was confirmed in all cases after birth. <b><i>Results:</i></b> In the study period between December 2019 and March 2020, 143 fetuses were recruited. In 130 fetuses (90.9%), the visualization of the CM was feasible. The mean value of the CMCd was 1.09 ± 0.16 cm. The 95% limits of agreement for the interobserver variability in measurement of the CMCd were 0.24 and 0.26 cm. The interobserver variability based on the intra-class correlation coefficient (ICC) for the CCMd was good (ICC = 0.81). We found a positive linear relationship between the CCMd and CRL. In all these fetuses, the CAL encountered the abdominal wall at or above the level of the cord insertion. <b><i>Conclusion:</i></b> In normal fetuses, the assessment of the CM position is feasible at the first trimester 3D ultrasound with a good interobserver agreement. The CM level was never found below the fetal umbilical cord insertion, while the CMCd was noted to increase according to the gestational age, confirming the “ascension” of the CM during fetal life.

AbstractAim of work:To determine whether fetal volume (FV) measured by three-dimensional (3D) ultrasound was able to detect fetuses at risk of low birth weight (primary outcome) and/or preterm labor (secondary outcome).Methods:One hundred pregnant women carrying a singleton living pregnancy who were sure of dates, and had a dating scan, with gestational age between 11 weeks and 13 weeks+6 days coming for routine first trimester nuchal translucency (NT) were examined by both two-dimensional (2D) and 3D ultrasound (Vocal System) for crown-rump length (CRL) and FV then followed up regularly every 4 weeks until 28 weeks then biweekly until 36 weeks then weekly until delivery both clinically and by ultrasound biometry.Findings:Eighty-seven cases had a normal outcome, while the remaining 13 cases had either preterm labor (four cases) or low-birth weight (nine cases). FV positively correlated with CRL (P=0.026), gestational age in weeks (P=0.002), neonatal body weight in grams (P=0.018) and neonatal body length at birth (P=0.04). A mean FV of 8.3 mmConclusion:3D assessment of FV in the first trimester provides an accurate method for predicting pregnancy outcome namely low birth weight and neonatal complications, however, it is a better positive predictor than a negative one.

Increased Nuchal Translucency

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.
