First‐trimester placental volume as a marker for chromosomal anomalies: preliminary results from an unselected population
Abstract
Objective: To compare first‐trimester placental volume in chromosomally abnormal and normal pregnancies. Methods: Placental volumes were routinely recorded at the time of nuchal translucency thickness measurement at 10–13 weeks of gestation. This was done using customized three‐dimensional ultrasound equipment and measurements were then converted to the placental quotient (placental volume/fetal crown–rump length). The possible difference in placental quotient between chromosomally normal and abnormal pregnancies was examined. Results: A total of 2863 pregnancies was evaluated, including 17 with major chromosomal defects (nine cases of trisomy 21, four of trisomy 18, two of trisomy 13, and one each of Turner syndrome and 48,XXY + 21). The median placental quotient in the chromosomally abnormal group (0.67) was significantly lower than that in the normal fetuses (0.98). In nine of the 17 affected pregnancies the quotient was below the 10th centile of the normal range. Conclusions: Assessment of placental volume may prove to be useful in first‐trimester risk assessment for chromosomal anomalies. Copyright © 2002 ISUOG

First trimester placental volume is associated with adverse pregnancy outcomes, including small-for-gestational-age infants born under the 10th or 5th centiles.
“Early placental volume (PV) has been associated with small-for-gestational-age infants born under the 10th/5th centiles (SGA10/SGA5).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
