“…Eighty‐three publications from 32 countries were identified; 14–96 the earliest was published in 1971 and the latest in 2008. In two publications, 49,76 multiple study designs were used, for instance AC using a longitudinal and a cross‐sectional design; the best described methodology with the highest quality score was used in the final analysis.…”

“…Conversely, it is arbitrary and illogical to exclude from analysis the outer percentiles of the ultrasound measurement values. For instance, measurements greater than 1.66 or two standard deviations from the mean 31,64 may well represent physiological healthy variability. Similarly, exclusion of cases with birthweight in the outer percentiles has been used by some studies 80,91 in order to define normal growth.…”

Background Reliable ultrasound charts are necessary for the prenatal assessment of fetal size, yet there is a wide variation of methodologies for the creation of such charts.Objective To evaluate the methodological quality of studies of fetal biometry using a set of predefined quality criteria of study design, statistical analysis and reporting methods.Search strategy Electronic searches in MEDLINE, EMBASE and CINAHL, and references of retrieved articles.Selection criteria Observational studies whose primary aim was to create ultrasound size charts for bi-parietal diameter, head circumference, abdominal circumference and femur length in fetuses from singleton pregnancies.Data collection and analysis Studies were scored against a predefined set of independently agreed methodological criteria and an overall quality score was given to each study. Multiple regression analysis between quality scores and study characteristics was performed.Main results Eighty-three studies met the inclusion criteria. The highest potential for bias was noted in the following fields: 'Inclusion/exclusion criteria', as none of the studies defined a rigorous set of antenatal or fetal conditions which should be excluded from analysis; 'Ultrasound quality control measures', as no study demonstrated a comprehensive quality assurance strategy; and 'Sample size calculation', which was apparent in six studies only. On multiple regression analysis, there was a positive correlation between quality scores and year of publication: quality has improved with time, yet considerable heterogeneity in study methodology is still observed today.Conclusions There is considerable methodological heterogeneity in studies of fetal biometry. Standardisation of methodologies is necessary in order to make correct interpretations and comparisons between different charts. A checklist of recommended methodologies is proposed.

“…with foetal anthropometric parameters. Morphological studies into umbilical cord structure have observed that umbilical cord in the face of foetal intrauterine growth restriction and hypertensive disorders with normal umbilical artery Doppler parameters exhibited reduced total vessel area and Wharton's jelly area in comparison with normal fetuses [15][16][17][18]. However, significant difference in the vein diameter was observed between the neonates of normotensive mothers and pregnancy induced hypertensive mothers respectively, with the PIHs having larger vein diameter.…”

Morphologic and morphometric characterization of the umbilical cord and vessel components could greatly assist in improving adverse maternal and neonatal outcomes. The aim of this study was to evaluate the relationship between morphometry of umbilical cord vessel components and neonatal outcome. A descriptive cross sectional study was conducted on 207 umbilical cords attached to placentae obtained from Victory Maternity Home and Clinic in Kumasi (Ghana) between November, 2013 and October, 2014. Umbilical cord length, diameter, and vessels' diameter were measured with the umbilical cord still attached to the placenta. Neonatal anthropometries were recorded within 24 hours after delivery. The mean ± SD of vein diameter between neonates of normotensive 3.36 (±0.88) and hypertensive mothers 3.82 (± 0.50) showed a significant difference. The body length of neonates with short umbilical cord length was significantly lower (p < 0.05) than that of those with long cord lengths. Quantitative analysis indicated a positive linear relationship in umbilical cord and its vessels components with neonatal anthropometry (p<0.05). In conclusion, the morphometry of the umbilical cord and its vessels could predict maternal and neonatal outcome and therefore would be useful in early detection and management of neonatal abnormalities.

Reappraisal of Fetal Abdominal Circumference in an Asian Population: Analysis of 50,131 Records

Abstract: To the best of our knowledge, our series is the largest sample of AC reported in the medical literature. We believe that the gestational age-specific nomogram of fetal AC is important for further clinical assessment of fetal growth.
