摘　　要：目的 探讨妊娠早中期胎儿体蒂异常(BSA)的超声表现特征,评价早期产前超声对BSA的诊断价值。方法 回顾性分析212 256例孕11~28+1周孕妇产前超声检查结果,总结检出BSA孕妇的产前超声特征,对比统计不同年龄、不同孕周的检出率。结果 检出BSA 27例,发生率为1.3/10 000。27例体蒂异常的胎儿中,单胎25例、双胎2例。所有病例中25.9%(7/27)存在胸腹壁联合缺损,74.1%(20/27)出现腹壁缺损,全部胎儿存在内脏外翻,且伴有不同程度的脊柱侧凸,其中8例伴有脊柱裂,3例出现颅骨缺损,1例脊柱裂同时合并有颅骨缺损;92.6%(25/27)病例脐带过短,同时22.2%(6/27)病例伴有单脐动脉;44.4%(12/27)病例存在肢体异常,14.8%(4/27)病例存在颈部透明层厚度(NT)增厚。结论 BSA最具特征性的表现为胸腹壁缺损、内脏外翻、脐带过短及脊柱侧弯,因此产前超声检查能早期发现并诊断BSA,具有较好的安全性及可靠性,并且为临床预后及选择合理的妊娠结局提供重要依据。Objective To investigate the ultrasonographic features of fetal body stalk anomaly(BSA) in the first and second trimesters of pregnancy, and to evaluate the diagnostic value of early prenatal ultrasound in BSA. Methods The results of prenatal ultrasonography of 212 256 pregnant women at 11 to 28+1week of gestation were analyzed retrospectively. The prenatal ultrasound characteristics of pregnant women with BSA were summarized, and the detection rates of different ages and gestational weeks were compared. Results BSA was detected in 27 cases, with an incidence of 1.3/10 000. Among the 27 fetuses with bodystalk anomaly, 25 were singleton and 2 were twin. In all cases, 25.9%(7/27) had thoracic abdominal wall defect in the joint and 74.1%(20/27) had abdominal wall defect, All the fetus had visceral eversion with varying degrees of scoliosis, including 8 cases with spina bifida, 3 cases with skull defect, and 1 case with spina bifida combined with skull defect. The umbilical cord was too short in 92.6%(25/27) cases, and single umbilical artery in 22.2%(6/27) cases. 44.4%(12/27) had limb abnormalities and 14.8%(4/27) had nuchal translucency(NT) thickening. Conclusions The most characteristic manifestations of BSA are defect of chest and abdominal wall, evagination of internal organs, short umbilical cord and scoliosis. Therefore, prenatal ultrasonography can detect and diagnose BSA early, and it is safe and reliable, it also provides an important basis for clinical prognosis and reasonable treatment of pregnancy outcome.
