目的探讨产前超声诊断胎儿神经管缺陷畸形的价值。方法回顾性分析经产前超声诊断的76例神经管缺陷畸形胎儿。结果无脑畸形26例,露脑畸形12例,脑膨出及脑膜膨出11例,单纯脊柱裂11例,无脑畸形合并脊柱裂5例,露脑畸形合并脊柱裂3例,脑膨出及脑膜膨出合并脑积水5例,脑膨出及脑脊膜膨出合并脊柱裂3例。结论超声作为一种安全简便的检查方法,只要熟悉掌握神经系统不同阶段的超声表现,规范化检查,注意追踪观察,就会大大提高神经管缺陷畸形的诊断正确率及早期发现率。
Objective To investigate the value of prenatal ultrasound in diagnosis of fetal neural tube defects. Methods Retrospective analysis of 76 cases of neural tube defect malformation fetus diagnosed by prenatal ultrasound. Results There were 26 cases without brain deformity, 12 cases with dendritic deformity, 11 cases with encephalocele and meningocele, 11 cases with simple spina bifida, 5 cases without sphenoidosis and spina bifida, 3 cases with congenital deformity and spina bifida, And meningocele combined hydrocephalus in 5 cases, encephalocele and meningocele combined spina bifida in 3 cases. Conclusion Ultrasound as a safe and easy method of examination, as long as familiar with the different stages of the nervous system ultrasound performance, standardized examination, pay attention to follow-up observation, it will greatly improve the diagnostic accuracy of neural tube defects and early detection rate.
