摘　　要：为了了解继发性卵黄囊的超声特点并估价异常卵黄囊和妊娠结局的关系。使用阴道超声对１０２例早孕妇女进行检测。结果：正常妊娠结局的卵黄囊大小从孕５周至孕１１周随孕周增加而增大，随后缩小，孕１２周后消失。卵黄囊大小异常在正常妊娠结局组和异常妊娠结局组间存在明显差异（Ｐ＜０．００１），其敏感性为８１．８２％，特异性为９２．５０％。In order to understand the feature of the secondary yolk sac(YS)and evaluate the abnormal YS versus the normal pregnancy outcome,102 first trimester pregnancies were investigated with transvaginal sonography.Result:In normal pregnancy course the YS diameter showed an increase from the 5th week to the 11th week gestation age,followed by a decrease and disappearance after 12th week,abnormal YS size was statistically significant(P<0 001).Abnormal YS induces adverse pregnacy outcome with a sensitivety 81 82%,a specificity 92 50%.These results indicate that transvaginal sonography examination of the diamater of the YS early in gestation is an important measure for predicting pregnancy outcome.
