摘要
目的探讨三维超声技术对胎儿四肢骨骼发育异常的诊断价值。方法2005年12月一2009年12月问，孕14。40周到我院进行常规超声筛查的胎儿，二维超声产前超声筛查发现胎儿四肢骨骼发育有异常的留存图像，同时用三维超声的表面成像模式和透明成像模式技术对病变部位进行三维成像，对比前后两种检查方法的图像，观察畸形部位及类型。结果在38974例胎儿中二维超声检出70例，三维超声检查检出78例，产后追踪时发现二维超声检查漏诊四肢畸形胎儿14例，漏诊病例为多指4例，多趾2例，缺趾2例，并指4例，手指姿势异常2例；三维超声检查漏诊四肢畸形胎儿6例，漏诊病例为多指2例，多趾2例，并指2例。三维超声对胎儿四肢畸形的检出率高于二维超声，主要在于提高胎儿手指、脚趾等畸形诊断的准确性。结论二维超声与三维超声对胎儿四肢长骨畸形的诊断上没有明显区别，但在胎儿手指、脚趾等细节畸形的诊断上，三维超声优于二维超声，而且三维超声图像直观，易于与孕妇沟通。
Objective To explore the diagnostic value of three-dimensional ultrasonography to fetal limb skeletal dysplasia. Methods From December 2005 to December 2009, the fetus with pregnancy of 14 to 40 weeks after routine ultrasound screening were given two dimensional prenatal ultra- sound screening, and we found fetal limb skeletal growth abnormalities retained images, meanwhile we used three-dimensional ultrasound surface imaging mode and transparent imaging mode techniques, the location and types of malformations observed by these two kinds of methods were compared. Results Among the 38 974 cases, 70 cases of abnormalities detected by two-dimensional method, while 78 ones detected by three-dimensional ultrasound method, during postpartum follow-up study, 14 cases of miss diagnosis were found, including 4 cases of polydactylism, 2 cases of polydactyly, 2 cases of toe absence, 4 cases of syndactyly, and 2 cases of abnormal finger posture; while in those with three-dimensional ultrasound method, there were only 6 cases found as miss diagnosis, including polydactylism, polydactyly and syndactyly, 2 cases for each. The detectable rate for fetal limb deformities of three-dimensional ultrasound was signifi- cantly higher than that of two-dimensional ultrasound method. The methods were mainly used to increase diagnostic accuracy for fetal fingers and toes deformities.Conclusions There is no obvious difference in fetal long bone deformity diagnosis between the methods of two-dimensioiial and three-dimensional ultrasound, but in the fetal fingers, toes and other details, the results of the three-dimensional ultrasound diagnosis is better than that of two-dimensional one. The three-dimensional ultrasound diagnosis image isintuitive which provides convenience for communicating with pregnant women.
