目的探讨三维超声在胎儿体表畸形的产前诊断中的临床意义。方法收集具有胎儿体表畸形的病例,对其三维图像进行回顾性分析,并与传统二维超声进行比较。结果共诊断胎儿体表畸形184例。二维超声诊断172例,疑诊11例,漏诊1例。三维超声诊断183例,漏诊1例。三维超声对体表畸形的诊断较二维超声更具优势。结论三维超声能提供直观立体、逼真的胎儿体表结构图像,丰富了诊断信息,能增强诊断信心,为二维超声的空间信息补充,两者联合应用可提高胎儿体表畸形的检出率。
Objective To investigate the clinical significance of three-dimensional ultrasonography in prenatal diagnosis of fetal body surface deformity. Methods The cases with fetal surface deformity were collected and their 3D images were retrospectively analyzed and compared with the traditional two-dimensional ultrasound. Results A total of 184 cases of fetal surface malformations were diagnosed. Two-dimensional ultrasound diagnosis of 172 cases, 11 cases of suspected, missed diagnosis in 1 case. 183 cases of three-dimensional ultrasound diagnosis, missed diagnosis in 1 case. Three-dimensional ultrasound on the diagnosis of body surface deformity than two-dimensional ultrasound more advantages. Conclusion Three-dimensional ultrasound can provide an intuitive and vivid fetal body surface structure images, enrich diagnostic information, enhance diagnostic confidence and complement spatial information of two-dimensional ultrasound, and the combination of the two can improve the detection rate of fetal surface deformity.
