目的探讨超声在产前诊断胎儿腭裂方面的价值。方法回顾性分析54例胎儿腭裂产前超声诊断特征,探寻腭裂的显示手法,并对腭裂进行超声分类。结果胎儿腭裂可分为原发腭裂、继发腭裂、完全腭裂、正中腭裂。54例腭裂胎儿中,原发腭裂9例,继发腭裂4例,完全腭裂36例,正中腭裂5例。其中继发腭裂4例产前超声检查全部漏诊,但原发、完全及正中腭裂超声诊断符合率高达92.59%,腭裂总的超声诊断符合率为85.18%。原发、完全及正中腭裂全部合并唇裂。本组继发腭裂均未合并唇裂。结论胎儿腭裂有特征性超声图像,依此特征诊断胎儿腭裂准确性较高;但单纯继发腭裂产前检出仍较困难。
Objective To explore the value of ultrasound in the diagnosis of fetal cleft palate. Methods A retrospective analysis of 54 cases of fetal cleft palate prenatal diagnosis of ultrasound features, to explore the cleft palate show techniques, and cleft palate ultrasound classification. Results Fetal cleft palate can be divided into primary cleft palate, secondary cleft palate, complete cleft palate, median cleft palate. 54 cases of cleft palate fetus, 9 cases of primary cleft palate, cleft palate in 4 cases, 36 cases of complete cleft palate, the median cleft palate in 5 cases. Among them, 4 cases of cleft palate were missed by prenatal ultrasound examination, but the coincidence rate of primary, complete and median cleft palate ultrasound was 92.59%. The coincidence rate of total cleft palate ultrasonic diagnosis was 85.18%. Primary, complete and the median cleft palate all combined cleft lip. This group of secondary cleft palate were not associated with cleft lip. Conclusion Fetal cleft palate has a characteristic ultrasound image, according to this feature diagnosis of fetus cleft palate higher accuracy; but cleft palate cleft palate prenatal only difficult.
