胎儿羊膜带综合征的超声诊断和鉴别诊断

目的通过对羊膜囊中的异常带状结构的检查，提高对羊膜带综合征诊断鉴别诊断的能力。方法对伴有宫内带状回声的孕妇进行超声检查。结果60例病例中7例是羊膜带综合征，53例有羊膜腔内异常带状回声，其中羊膜外妊娠7例，羊膜片4例，子宫不全纵隔24例，胎儿颈部水囊瘤2例，胎儿全身水肿11例，未闭合的胚外体腔5例。结论羊水中的带状结构并非都是羊膜带。在检查过程中，要注意询问患者的病史，仔细分辨羊膜腔内的带状结构的特点及毗邻关系。早期在宫内观察到带状结构者，应严密随诊。

Ultrasound diagnosis of amnniotic bands syndrome-clinical analysis

Objective To improve the diagnosis of amniotic bands syndrome with ultrasound. Methods All pregnant women underwent ultrasonographic examination to observe the intra amniotic band like structures. Results Among 8771 women undergone ultrasound examination, 60 were found with intra amniotic band structure. Seven cases were diagnosed as amniotic bands syndrome and 53 intra amniotic band like structures included extra amniotic pregnancy(7), amniotic sheets(4), incomplete uterine septum(24), fetal nuchal cystic hygroma(2), fetal nuchal and trunk edema(11) and disclosed extra embryo sac(5). Conclusions Not all the intra amniotic band like structures is amniotic band. But any abnormal structures detected in early stage should be closely followed up.
