Abstract

Objective: To examine the potential value of routine measurement of cervical length in singleton pregnancies at 23 weeks of gestation in the prediction of the risk for early spontaneous preterm delivery. Methods: Cervical length was measured by sonography at 23 weeks in 2567 singleton pregnancies in women attending for routine antenatal care. In 43 women, the length was ≤15 mm and 21 of these were managed expectantly, whereas in 22 cases a cervical cerclage was placed. In the pregnancies that were managed expectantly, the relation between cervical length and preterm delivery was examined and the risk of spontaneous delivery at ≤ 32 weeks was estimated. Results: Cervical length at 23 weeks was ≤ 15 mm in 1.7% of cases; this group contained 86%, 58% and 20% of pregnancies that delivered spontaneously at ≤ 28, ≤ 32 and ≤ 36 weeks, respectively. The risk for delivery at ≤ 32 weeks decreased from 78% at a cervical length of 5 mm to 4% at 15 mm and 0.5% at 50 mm. Conclusions: Cervical length at 23 weeks is ≤ 15 mm in < 2% of the population; this group contains about 90% and 60% of the women delivering at ≤ 28 and ≤ 32 weeks, respectively. Measurement of cervical length provides accurate prediction of risk for early preterm delivery. Copyright © 1998 International Society of Ultrasound in Obstetrics and Gynecology

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.
