摘要
236例B超异常胎儿，184例显示胎儿各种畸形，另52例为胎儿宫内生长迟缓，进行了染色体分析。184例B超胎儿畸形者，166例染色体核型正常217例染色体核型异常；1例无法分析核型。52例胎儿宫内生长迟缓，49例染色体核型正常；3例核型异常。17例合并有染色体校型异常的畸形胎儿均予以治疗性终止妊娠，另3例胎儿宫内生长迟缓合并染色体核型异常者也预后不良。结果提示B超检查在遗传学筛选诊断上具有很大的价值，应予以推广应用。
Chromosome analysis was carried out among 236 fetuses presented abnormality by scanning: 184 fetuses presented various malformation and 52 intrauterine growth retardation (IUGR).166 of 184 cases were normal in chromosome karyotype; 17 demonstrated abnormality. One chromosome karyotype was beyond analysis. 49 of 52 IUGR fetuses were normal in chromosome karyotype; 3 cases presented abnormality. Pregnancy of 17 malformational fetuses with abnormal karyotype was ceased therapeutically. 3 fetuses with IUGR and abnormal karyotype went worse afterward. The results reveal that ultrasound B type is very valuable, sensitive and special for hereditary screening diagnosis.
