目的应用超声监测早孕卵黄囊的形态与大小 ,探讨异常卵黄囊与妊娠的相关性。方法采用腹部和阴道超声对 15 2例孕妇进行卵黄囊检测 ,观察其形态 ,测量卵黄囊的大小 ,并随访孕妇至妊娠分娩。结果卵黄囊从早孕 5～ 10周逐渐增大随后缩小 ,孕 12周后消失 ;妊娠正常 12 8例 ,胚胎停止发育 2 2例与胎儿畸形 2例。卵黄囊大小的异常在正常妊娠组与异常妊娠组之间有明显差异 (P≤ 0 .0 0 1)。异常卵黄囊的妊娠 ,预后不良。
ObjectiveTo monitor the morphology and size of yolk sac by ultrasonography during early pregnancy and evaluate the correlation between abnormal yolk sac and pregnancy. Methods The morphology and size of yolk sacs in 152 pregnant women were detected by vaginal and abdominal ultrasonography, follow-up was continued till their delivery. Results Of the group, there were 128 cases of normal pregnancy, 22 cases of embryo death and 2 cases of fetal malformation. The size of yolk sacs in normal pregnancy became bigger as the gestation proceeded from the fifth to the tenth week, then changed to smaller until they disappeared after the twelfth week of gestation. Significant difference existed between the size of yolk sacs in normal and abnormal pregnancy group (P≤ 0.001 ). Poor prognosis was observed in pregnancies with abnormal yolk sacs. Conclusion The health status examination of yolk sacs by ultrasonography during early pregnancy can be used as a measure to predict the development and alteration of pregnancy. [
