目的 评价产前超声对胎儿脊髓纵裂的诊断价值。
方法 回顾性分析我院产前超声拟诊6例胎儿脊髓纵裂的产前超声特征，总结胎儿期脊髓纵裂的声像图特征及伴发畸形。
结果 6例胎儿产前超声5例清晰地显示出椎管内强回声分隔，1例为椎管内无回声囊性结构；6例对应部位椎弓间距增宽并椎管扩张；5例脊髓圆锥位置下移；3例横切面可显示脊髓受压分裂为两半；1例合并开放性脊柱裂并脊髓脊膜膨出，2例合并多发半椎体并脊柱侧弯。
结论 胎儿期脊髓纵裂的典型产前超声特征是椎管内强回声并椎弓间隙增宽，常合并脊髓圆锥位置以下及其它脊柱畸形，产前超声有重要的诊断和鉴别诊断价值。 |

| Abstract：
Objective To evaluate the value of prenatal ultrasound in the diagnosis of fetal split cord malformation.
Methods The prenatal ultrasonographic characteristics of 6 cases of fetal split cord malformation in our hospital were analyzed retrospectively, and the ultrasonic features and associated malformations of fetal split cord malformation were summarized.
Results In 6 fetuses, 5 cases showed clearly hyperechoic separation in the spinal canal, 1 case showed no echoic cystic structure in the spinal canal; 6 cases showed widened arch spacing and spinal canal expansion in the corresponding position; 5 cases showed the position of the cone of the spinal cord moving down; 3 cases showed that the spinal cord was divided into two parts by compression in the transverse section; 1 case was combined with open spina bifida and myelomeningocele, and 2 cases were combined with multiple hemivertebra and scoliosis.
Conclusion The typical prenatal ultrasound features of fetal split cord malformation are hyperechoic in spinal canal and widened space of vertebral arch, often associated with spinal cord below cone position and other spinal deformities. Prenatal ultrasound has important diagnostic and differential diagnostic value. |
