【摘要】：目的探讨二维及三维超声对胎儿蝴蝶椎并肋骨融合畸形的产前诊断价值,比较蝴蝶椎与半椎体的产前超声表现。方法回顾性分析我院诊断的11例胎儿脊椎肋骨异常病例的产前二维及三维超声表现,并与产后超声及其他影像学检查进行对照。探索三维超声较二维超声检查在诊断椎体及肋骨病变位置、形态改变细节等方面的优势。结果超声显示11例胎儿脊椎肋骨异常中,单发椎体畸形4例,多发椎体畸形7例,其中1例发生在颈段,5例发生在胸段,1例颈段、胸段同时发生,2例胸、腰段同时发生,2例颈、胸、腰段同时发生。4例为单发蝴蝶椎,3例为蝴蝶椎合并肋骨融合和半椎体,3例为蝴蝶椎合并半椎体,1例为蝴蝶椎合并肋骨融合。11例胎儿超声检查均可见脊柱形态改变或椎体排列异常,产前MRI检查与超声结果基本相符,其中3例经出生或引产后影像学证实。结论二维及三维超声作为一种无创、可重复性高的成像技术,可特征性地反映脊柱、椎体及肋骨排列的异常,对胎儿蝴蝶椎及肋骨融合畸形的产前诊断具有重要价值。
[Abstract]:Objective to investigate the value of 2D and 3D ultrasound in prenatal diagnosis of fetal butterfly vertebrae and rib fusion malformation, and to compare the prenatal ultrasonographic findings between butterfly vertebra and hemivertebra. Methods Antepartum 2D and 3D ultrasound findings of 11 cases of fetal spinal rib abnormalities diagnosed in our hospital were retrospectively analyzed and compared with postpartum ultrasound and other imaging examinations. To explore the advantages of 3D ultrasound in diagnosing the location of vertebral body and rib lesions and the details of morphological changes. Results among 11 cases of fetal spinal rib abnormality, 4 cases were single vertebral body malformation, 7 cases multiple vertebral body malformation, among which 1 case occurred in cervical segment in 1 case, thoracic segment in 2 cases, lumbar segment in 2 cases. Chest, Lumbar segment occurred at the same time. 4 cases were single butterfly vertebrae, 3 cases were butterfly vertebra with rib fusion and 3 cases were butterfly vertebrae combined with half vertebrae. 1 case was butterfly vertebra with rib fusion. Or abnormal arrangement of the vertebrae, Prenatal MRI was basically consistent with ultrasound findings, 3 of which were confirmed by imaging after birth or induced labor. Conclusion as a noninvasive and reproducible imaging technique, 2D and 3D ultrasound can reflect the abnormal arrangement of spine, vertebra and rib, and have important value in prenatal diagnosis of fetal butterfly vertebrae and rib fusion malformation.
