摘要
目的探讨超声在早孕卵黄囊预测妊娠结局的意义。方法对100例早孕妇女卵黄囊的声像图特点进行分析及对孕妇进行随访。结果正常卵黄囊超声显像呈球形的囊性结构,卵黄囊大小从孕5周至孕10周随孕周增加而增长。最小直径3mm,最大直径不超过6mm,随后缩小,孕12周后不再超声显示。卵黄囊大小正常与卵黄囊异常(包括未见卵黄囊显示及大小异常)在妊娠结局中存在明显差异(P<0.01)。结论超声监测孕早期卵黄囊直径可预测妊娠结局,可指导临床采取有效的治疗措施。
Objective To explore the significance of ultrasound of yolk sac for predicting pregnancy outcome in early pregnancy. Methods The sonographic characteristics of yolk sac of 100 women with early pregnancy were analyzed and the pregnant women were followed up. Results Normal yolk sac ultrasound imaging showed spherical cystic structure, yolk sac size increase d from 5 weeks to 10 weeks of pregnant with the increasing of gestational age. Minimum diameter was 3 mm, maximum diameter was less than 6 mm, then reduced, after 12 weeks of pregnancy ultrasound did not showed. Normal yolk sac size and abnormal yolk sac （including no show of yolk sac and the size of abnormal yolk sac） had significant differences in pregnancy outcome （P 〈0.01）. Conclusion Ultrasound monitoring for yolk sac diameter of early pregnancy can predict pregnancy outcomes and can guide effective clinical treatment.
