三维超声在胎儿半椎体诊断中的应用价值

Application value of three-dimensional ultrasound in the prenatal diagnosis of hemivertebrae

目的:探讨三维超声(3DUS)在胎儿半椎体诊断中的应用及临床价值。方法:回顾性分析诊断的12例胎儿半椎体病例的产前二维超声(2DUS)及3DUS声像图表现,并与引产后影像学检查及病理结果进行对照。结果:3DUS胎儿半椎体的声像图比2DUS更准确直观;12例中单发4例(33.3%),合并其他系统畸形8例(66.7%),分别是泌尿系统畸形4例,心脏畸形2例,单脐动脉2例,肠道闭锁、肺囊腺瘤样病变、唇腭裂、双足内翻各1例。结论:3DUS对胎儿半椎体及其相关畸形的诊断是较准确的,具有显著的临床价值。

Objective：To investigate the clinical value of three-dimensional ultrasound（3DUS） in the prenatal diagnosis of hemivertebrae. Methods：We retrospectively analyzed the two-dimensional ultrasound（2DUS） and 3DUS sonographic manifestations of 12 fetus with hemivertebrae in our hospital,and compared with the radiographic examination and pathological results after the induction of labor. Results：The sonogram of the 3DUS was more intuitive and accurate than the 2DUS in the prenatal diagnosis of hemivertebrae;In the total 12 fetuses,4 fetuses（33.3%） had single malformation,8 fetuses（66.7%） had additional anomalies,of which 4 fetuses with urinary tract abnormalities,2 fetuses with cardiac malformations,2 fetuses with single umbilical artery,1 fetuses with duodenal atresia,1 fetuses with pulmonary cystadenoma-like lesions,1 fetuses with cleft lip and palate,1 fetuses with feet varus. Conclusion：3DUS diagnosis of fetal with hemivertebrae and related abnormalities is accurate,with significant clinical value.
