[摘要] 目的 探讨B型超声(B-US)及彩色多普勒血流显像(CDFI)对胎儿畸形的诊断。方法 回顾性分析8307例中晚期孕妇，B型超声及彩色多普勒血流检查、诊断胎儿畸形108例。结果 胎儿畸形发病率为1.3%。中枢神经系统畸形发病率最高，占胎儿畸形87.76%(95/108)。其中，无脑儿占首位37.04%(40/108)，脑积水次之33.33%(36/108)。并且多器官畸形占28.70%(31/108)。胎儿脑积水、无脑儿合并其他器官畸形占脑积水、无脑儿总数27.63%(21/76)。结论 超声检查、方便、无创无痛，并可多次重复检查，实时观察胎儿各部位、各器官的情况。及早诊断出胎儿畸形，有助于终止妊娠。实行优生优育，并为临床诊断提供重要依据。[关键词] 彩色多普勒血流显像；胎儿畸形；B型超声

[Abstract] Objective To probe into the action of two dimensional ultrasonography and CDFI in diagnosing fetal malformation.Methods We reviewed and analysed 8307 cases of pregnancy over 18 weeks who underwent 2-DUS and CDFI examinations.108 cases were found to have fetal malformation.Results The incidence rate of fetal malformation was 1.3%.The incidence of malfarmation in central nervous system was the higest,87.96%(95/108).In the 108 cases,the anencephaly was 37.04%(40/108).Hydrocephalus was 33.33%(36/108) and the multi-organs malformation was 28.70%(31/108).Fetal malformation hydrocephalus,the anencephaly and other organs malformation were 27.63%(21/76).Conclusion The practice of 2-DUS and CDFI is simple without trauma and pain.All the parts and apparatuses of the fetues in the womb can constantly be observed and re-examined by 2-DUS so that fetal malformation can be diagnosed as soon as possible,but with reliable results for quick diagnosis of fetal malformations.Its clinical value is great. ......
