Abstract

BACKGROUND

A difference more than 15-40% in birth weight of twins can predict perinatal complications. As significant difference in twins growth has a very important effect on pregnancy and perinatal complications, this study aimed to evaluate crown-rump length discordance (ΔCRL) in the first trimester of pregnancy and its correlation with perinatal complications.

METHODS

A total number of 118 women in the first trimester of twin pregnancy underwent ultrasound examination to measure ΔCRL. Then, at the time of delivery, perinatal complications in twins were recorded and the correlation between ΔCRL and perinatal complications were evaluated.

RESULTS

Among 118 studied mothers with twin pregnancy, ΔCRL was normal (< 11%) in 96 cases (81.4%) and high (≥ 11%) in 22 cases (18.6%). Birth weight discordance was normal (< 20%) in 103 cases (87.3%) and above normal (≥ 20%) in 15 cases (12.7%). The results revealed a significant correlation between higher frequency of small for gestational age (SGA) and high ΔCRL (more than 11%) (p = 0.01).

CONCLUSIONS

Our study concluded that SGA has a significant relationship with high ΔCRL (> 11%).

摘要

背景

双胞胎出生体重相差超过15%-40%可预测围产期并发症。由于双胞胎生长的显著差异对妊娠和围产期并发症有非常重要的影响，本研究旨在评估孕早期的头臀长不一致性（ΔCRL）及其与围产期并发症的相关性。

方法

共有118例双胎妊娠孕早期妇女接受超声检查以测量ΔCRL。然后，在分娩时，记录双胞胎的围产期并发症，并评估ΔCRL与围产期并发症之间的相关性。

结果

在118例接受研究的双胎妊娠母亲中，96例（81.4%）的ΔCRL正常（<11%），22例（18.6%）的ΔCRL较高（≥11%）。出生体重不一致性在103例（87.3%）中正常（<20%），在15例（12.7%）中高于正常（≥20%）。结果显示，小于胎龄儿（SGA）的较高发生率与高ΔCRL（超过11%）之间存在显著相关性（p=0.01）。

结论

我们的研究得出结论，SGA与高ΔCRL（>11%）有显著关系。
