摘要
目的：探讨三维超声在胎儿四肢畸形筛查中的价值。方法：选择常规产前检查的孕妇10 862例,采用二维超声模式对胎儿进行全面扫查,对可疑四肢畸形或二维超声显示欠佳的部位采用三维超声检查,应用卡方检验比较三维超声与二维超声对胎儿四肢畸形的诊断率。结果：共35例胎儿存在四肢畸形,以手足内外翻、四肢短小和多指（趾）发生率较高,二维超声检出四肢畸形25例（71.4%）,诊断不明9例（其中8例经三维超声确诊）,漏诊1例;三维超声检出四肢畸形胎儿33例（94.3%）,诊断不明1例,漏诊1例,三维超声对胎儿四肢畸形的诊断率高于二维超声（χ~2=6.046,P=0.014）,差异有统计学意义。结论：三维超声成像可提供更多的空间信息,图像清晰、直观,诊断胎儿四肢畸形准确率高。
Objective： To assess values of real-time three-dimensional ultrasound imaging in screening deformities of f fetal limbs.Methods： A total of 10862 pregnant women undergoing regular prenatal examination received two-dimensional ultrasound detection. For fetuses suspected with limb deformity or poor imaging of the extremities on two-dimensional ultrasound were given three-dimensional ultrasound scanning. Chi-square test was performed to compare the coincidence rate by two different ultrasonic modes.Results： Limb deformity was detected in 35 fetuses,and highly associated with hand inversion /manus valga or talipes valgus / varus,short limbs and overlapped multi fingers / toes. Two-dimensional ultrasound revealed extremity deformity in 25 cases（ 71.4%）. Nine cases of ambiguity by two-dimensional mode was confirmed by three-dimensional ultrasound in 8 and misdiagnosis in 1. Limb deformities were detected by three-dimensional ultrasound in 33 cases（ 94.3%）,1 case was unclear,and another 1 was misdiagnosed. The diagnostic rate of three-dimensional ultrasound was higher than the two-dimensional mode for detecting the fetal limb deformity（ χ~2= 6.046,P = 0.014）.Conclusion： The threedimensional ultrasound imaging can accurately reveal the fetal limb deformity because this mode may provide more spatial information,clear image and visualization.
