摘　　要：目的探讨产前超声早期诊断胎儿体蒂异常的价值。方法回顾性分析我院产前超声诊断12例11～14孕周胎儿体蒂异常的声像图表现及随访结果，分析胎儿体蒂异常的超声声像图特点。结果12例胎儿体蒂异常均有较大的腹壁或胸腹壁缺损，内脏器官疝出和脊柱不同程度扭曲；9例脐带异常，其中7例脐带过短或缺如，4例单脐动脉（2例伴脐带过短）；4例合并肢体畸形；4例颈部透明带增厚。结论胎儿体蒂异常是一种严重胎儿畸形，产前超声检查是早期诊断胎儿体蒂异常的可靠方法，对其早期诊断及临床处理具有重要价值。Objective To explore the value of prenatal ultrasound in early diagnosis of fetuses with body stalk anomaly（BSA）. Methods A retrospective study was performed in 12 cases with BSA,inctuding ultrasound images and follow-up results. The ultrasonic features of BSA were analyzed. Results In the twelve cases with body stalk anoma ly, the common ultrasonographic features include a large abdominal/thoracoabdominal wall defect, eventration of muhi- ple visceraI organs,severe vertebra and lower Iimb abnormalities. Nine cases umbilical cord anomaly including 7 cases short or absent umbilical cord,mostly associated with a single umbilical artery. Four cases presented with limb deform ities and 4 cases nuchal translucency（NT）. Conclusions Body stalk anomaly can be diagnosed accurately by prenatal ultrasonography, the first trimester ultrasound screening can help ensure the early and accurate diagnosis of this severe and lethal malformation.
