摘要
目的探讨早孕头-臀长差在预测双绒毛膜双胎胎儿发育不一致中的意义。方法以本地区体外受精-胚胎移植受孕的279例妊娠妇女为研究对象,在取卵后11-13+6孕周经腹测量胎儿头-臀长。根据双胎早孕头-臀长差将样本分为观察组及对照组。观察组:双胎早孕头-臀长差≥10%,共26例;对照组:双胎早孕头臀长差<10%,共253例。排除死产或双胎妊娠中单绒单羊、单绒双羊的胎儿,随访全妊娠期,分析两组胎儿出生时双胎体重发育不一致的发生率。结果观察组胎儿出生时双胎体重发育不一致发生率为26.9%(7/26),明显高于对照组的12.6%(32/253)(P<0.05)。结论双绒毛膜双胎胎儿早孕头-臀长差≥10%时,双胎胎儿出生时体重发育不一致发生率明显增高。
Objective To investigate the significance of first-trimester crown-rump-length（CRL） discrepancy in predicting the growth discordance in dichorionic twin gestation.Methods CRL was measured in 279 pregnant women after in-vitro fertilization（IVF） who underwent a scan at 11-13＋6 weeks of gestation.Gestational age was calculated from the day of oocyte retrieval.According to CRL discrepancy,the pregnant women were divided into two groups of A（26 cases,CRL difference ≥10%） and B（253 cases,CRL difference〈10%）.The pregnant women with stillbirth,withdrawing fetus or monochorionictwins were excluded.The discordant birth weight between two groups was analyzed.Results The incidence rate of discordant birth weight was higher in group A than that in group B（26.9% vs 12.6%）（P〈0.05）.Conclusion The incidence rate of discordant birth weight is higher in CRL difference ≥10%.
