早孕妊娠囊小于孕周者与胚胎停止发育的关系探讨

Dissucssion on the Relationship between the Gestational Sac of Early Pregnancy and the Discontinue Development of Embryo

目的探讨早孕期胚胎存活而妊娠囊小于孕周者与胚胎停止发育的关系。方法回顾性分析2013年7月-2014年3月在我院门诊进行超声诊断且治疗的早孕期妊娠囊小于孕周的孕妇39例,随访其妊娠结局。结果 39例妊娠囊超声检查最大直径11 mm,最小直径3 mm,其中无卵黄囊者11例,有卵黄囊者28例,卵黄囊大于8 mm者5例,3~8 mm者15例,小于3 mm者8例。超声诊断1~2周后复查超声,发现胚胎停止发育者24例,均为无卵黄囊、卵黄囊大于8 mm或小于3 mm者。15例胚胎存活,均为卵黄囊大小在3~8 mm者,且妊娠到足月。结论早孕妊娠囊小于孕周伴无卵黄囊、卵黄囊大于8 mm或小于3 mm者易发生胚胎停止发育;妊娠囊小于孕周但卵黄囊大小在3~8 mm者预后较好,超声检查能为临床医生及患者提供胚胎预后发育情况,早期甄别胚胎停止发育。

Objective To investigate the relationship between the gestational sac of early pregnancy and the development of the embryo.Methods 39 cases of pregnant women whose gestational saces were less than that of gestational weeks by ultrasound diagnosis were analyzed retrospectively in July of 2013 march of 2014 in our hospital,followed up the outcome of pregnancy.Results The largest diameter in 39 cases was 11 mm,minimum diameter of 3 mm,including 11 cases without yolk sac,28 cases with yolk sac including 5 casesof more than 8 mm,15 cases of 3 ～ 8 mm,8 cases of less than 3 mm according to the size of yolk sac.After 1 ～ 2weeks of ultrasonic examination,24 cases were found that embryos had stopped development,all of whom were no yolk sac,yolk saces were more than 8 mm or less than 3 mm.15 cases were found embryoes survival whose yolk saces sizes were 3 ～ 8 mm and developed well.Conclusion For those with their gestational saces less than that of the gestational weeks with no yolk sac,yolk saces of more than 8mm or less than 3 mm,embryonic airest is easy to occur.The gestational sac is smaller than that of the gestational weeks but the yolk sac size is between 3 ～ 8 mm,their dembryonic development is better.Ultrasound can provide clinicians and patients with embryonic prognosis of development,early screening to stop the development of embryos.
