摘要
目的：探讨二维及三维超声在胎儿半椎体畸形诊断中的应用及临床价值。方法：分析诊断的12例胎儿半椎体畸形的二维及三维超声图像特点。结果：胎儿半椎体畸形二维超声表现具有特征性，其三维超声可直观显示脊柱侧弯程度、准确定位病变椎体，是二维超声诊断的重要补充。12例胎儿半椎体畸形中，单发椎体畸形5例，多发椎体畸形7例，其中6例发生在胸段，3例发生在腰段，1例发生在骶尾段，1例颈段和胸段同时发生，1例胸段和腰段同时发生。4例为单纯半椎体畸形，8例合并其他系统畸形，分别是心脏畸形4例，泌尿系统畸形2例，肢体发育异常2例，神经系统畸形2例；羊水过少2例。结论：超声产前筛查胎儿半椎体畸形具有典型声像图表现，有重要的临床价值。
Abstract
Objective: To investigate the clinical value of two-dimensional and three－dimensional ultrasound in prenatal diagnosis of hemivertebrae. Methods: To analyze two-dimensional and three－dimensional ultrasonography imaging features in hemivertebrae. Results: Two-dimensional ultrasound has many characteristics of hemivertebrae. Three-dimensional ultrasound can be used to visualize the degree of scoliosis. Accurate positioning of the vertebrae, is important for performing two-dimensional ultrasound technique. Among the 12 fetuses, 5 fetuses had single vertebral deformity, 7 fetuses had multiple vertebral deformities, 6 cases occurred in the thoracic spine, 3 cases in the lumbar spine, 1 case in the sacral segment, 1 case in the cervical and thoracic, 1 case in the thoracic and lumbar. Besides the vertebral defect, 8 fetuses had additional anomalies, of which 4 fetuses had cardiac malformations, 2 fetuses had urinary tract abnormalities, 2 fetuses had abnormal limb development, 2 fetuses had central nervous system malformations, 2 fetuses had oligohydramnios. Conclusion: We found that hemivertebrae has typical ultrasonic features, ultrasound had significant clinical value.
