Abstract

A two-weekly ultrasound schedule for monochorionic twins is widely endorsed. There is a lack of robust data to inform a schedule for the surveillance of dichorionic gestations. We aimed to determine how ultrasound performed at 2- or 4-weekly intervals (or 4 weekly before 32 weeks and 2 weekly thereafter) may impact the prenatal detection of fetal growth restriction (FGR) and ultimately influence timing of delivery. In a consecutive cohort of 789 dichorionic twin pregnancies prospectively recruited for the multicenter ESPRiT study, ultrasound determination of fetal growth and interrogation of umbilical and middle cerebral artery Doppler were performed every 2 weeks from 24 weeks' gestation until delivery. Complete delivery and perinatal outcome data were recorded for all pregnancies. Where delivery was prompted by FGR, abnormal umbilical artery (UA) Doppler examination or poor biophysical profile, and in the absence of ruptured membranes, onset of labor, preeclampsia or antepartum haemorrhage, the delivery was considered 'ultrasound-indicated'. For ultrasound-indicated deliveries, detection probabilities for fetal growth restriction / abnormal umbilical artery Doppler / poor biophysical were determined according to the interval between examinations, by suppressing alternate examination data. Among 789 DC twin pregnancies, 66 pairs (8%) had an "ultrasound indicated" delivery. Detection of FGR was reduced from 88% to 69% and detection of abnormal UA Doppler was reduced from 82% to 62% when a four-weekly ultrasound schedule was simulated. Both of these reductions reached statistical significance. There was a non-significant trend toward a reduction in the recording of oligohydramnios with a 4-week interval between examinations. This study suggests that the two-weekly ultrasound surveillance program which is currently recommended for monochorionic twins should be extended to dichorionic gestations.

Attention Score in Context

This research output has an Altmetric Attention Score of 11. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 January 2020.
All research outputs
#1,740,466
of 15,371,078 outputs
Outputs from American Journal of Obstetrics & Gynecology
#1,675
of 9,706 outputs
Outputs of similar age
#32,494
of 236,461 outputs
Outputs of similar age from American Journal of Obstetrics & Gynecology
#21
of 133 outputs
Altmetric has tracked 15,371,078 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 9,706 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.5. This one has done well, scoring higher than 82% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 236,461 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 86% of its contemporaries.
We're also able to compare this research output to 133 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 84% of its contemporaries.
