OBJECTIVE
To assess the impact of a sonographic diagnosis of marginal placental cord insertion on birth weight and duration of pregnancy.
METHODS
A retrospective chart review was performed for 100 singleton pregnancies with prospectively identified marginal placental cord insertion.
RESULTS
Birth weights below the 10th percentile occurred in 6.25% of pregnancies without preeclampsia. Spontaneous preterm delivery occurred in 7.3% of pregnancies without preeclampsia. Rates of birth weight below the 10th percentile and preterm delivery were not significantly different from those in the general population. Preeclampsia developed in 4 patients; all had elective preterm deliveries, and all gave birth to neonates with birth weights below the 10th percentile.
CONCLUSIONS
A prenatal diagnosis of marginal placental cord insertion is not associated with increased risk of growth impairment or preterm delivery.
目的
评估超声诊断边缘性脐带胎盘插入对出生体重和孕期时长的影响。
方法
对100例经前瞻性确定为边缘性脐带胎盘插入的单胎妊娠进行回顾性病历审查。
结果
在无先兆子痫的妊娠中，出生体重低于第10百分位数的情况占6.25%。无先兆子痫的妊娠中有7.3%发生自发性早产。出生体重低于第10百分位数和早产的发生率与一般人群无显著差异。4例患者发生先兆子痫；均进行了选择性早产，且均分娩出出生体重低于第10百分位数的新生儿。
结论
产前诊断边缘性脐带胎盘插入与生长受限或早产风险增加无关。
