超声对胎儿唇腭裂畸形的诊断价值

目的:探讨B超及CDFI诊断胎儿唇腭裂畸形的价值。方法:采用B超及CDFI对孕20~41周的胎儿进行唇面部超声检查,口唇清晰显示者与引产或足月产后进行对照。结果:在胎儿面部清晰显示的10 521例中共发现胎儿唇腭裂畸形19例,超声产前检出16例,漏诊3例,检出率84.21%。结论:胎儿唇弓回声中断、牙槽骨“双弧形”和硬腭“弧形”强回声不连续分别是唇裂、牙槽骨裂和硬腭裂的直接征象;上唇结节回声失落,鼻小柱向健侧移位,患侧鼻翼内陷是唇腭裂的常见声像图表现,CDFI胎儿上、下唇动脉分布异常或中断为间接征象。

The value of ultrasonography in diagnosis of the fetal cleft lip and cleft palate

Objective: To explore the value of B-ultrasonography and CDFI in diagnosis of fetal cleft lip and cleft palate.Methods: About 20~41 weeks fetuses' faces were examined by ultrasonography and CDFI and were proved after abortion or born.Results:Nineteen fetuses with cleft lip or cleft palate were found in 10521 fetuses whose face were shown clearly,16 cases were found by ultrasonography befor they were born,3 cases were missed,the sensitivity was 84.21%. Conclusion: The echo interruption of fetal lip-bow,the strong echo discontinuious of tooth trough bone"double-arc" and hard palate"arc"were direct sign of cleft lip,cleft tooth trough bone and cleft hard palate.The echo attenuated of the upper lip node,nasoseptal displacement towards the healthy side and the collaps of the unhealthy side nose wing are common signs.On CDFI,abnormal distribution or interruption of fetuses' upper and low lip artery were indirect symbol.
