摘要目的 探讨超声对胎儿体蒂异常的诊断价值.方法 回顾分析我院诊断的5例胎儿体蒂异常病例的产前超声表现,并与病理结果进行对照.结果 5例胎儿超声检查均可见较大的腹壁或胸腹壁缺损、内脏器官疝出、严重的脊柱及肢体异常以及脐带过短或缺如,多数伴有单脐动脉.所有胎儿均人工终止妊娠,其中2例胎儿经尸检病理证实产前超声诊断结果.结论 胎儿体蒂异常是一种致命的严重胎儿畸形,产前超声检查可通过其特征性表现特别是脐带异常表现进行诊断及鉴别诊断,孕11～14周超声筛查有助于本病的早期诊断及处理.

abstractsObjective To investigate the diagnostic value of ultrasonography in fetal body stalk anomaly.Methods In a retrospective analysis the sonographic findings of five fetuses with body stalk anomaly diagnosed in our hospital were reviewed and compared with the pathological findings.Results In the five fetuses with body stalk anomaly.the common uItrasonographic features include a large abdominal/thoracoabdominal wall defect,eventration of multiple visceral organs,severe vertebra and lower limb abnormalities,and a short or absent umbilical cord,mostly associated with a single umbilical artery.All of the cases chose termination of pregnancy,and two of whom underwent autopsy and the results confirmed the prenatal sonographic findings.Conclusions Body stalk anomaly can be diagnosed accurately by prenatal ultrasonography,especially with the finding of abnormal umbilical cord.The first trimester ultrasound screening can help ensure the early and accurate diagnosis of this severe and lethal malformation.
