中孕期超声诊断胎儿先天性结构畸形分析

目的提高对胎儿先天性结构畸形的诊断水平，降低出生缺陷，提高人口素质。方法回顾性分析2004年1月-2010年4月在我院行产前检查发现的96例胎儿先天性结构畸形的孕妇常规超声检查结果，总结其声像网特点，并与出生或引产后解剖相对照。结果本研究畸形发生率为3．15％，发病率居前三位的分别为神经系统、心血管系统、非免疫性胎儿水肿（a-地中海贫血），同时发现胎儿先天性结构畸形有特异性的超声表现，且与孕妇病史、接触史及年龄密切相关。结论超声检查对胎儿先天性结构畸形的筛查有重要的临床意义。

Analysis of Diagnosing Fetus Congenital Structural Eformity by Ultrasonography during Middle Trimester

Objective To enhance the knowledge level of ultrasonic characteristic of fetus congenital structural eformity, to decrease born defect, to improve population quality. M ethods Ninetysix fetuses, who were enrolled in the study with congenital structural abnormality, were assessed with the help of Ultrasound. To retrospectively analyse their ultrasound results, to summarize their ultrasound characteristics,and to contrast with the results of the anatomy after born or induction. Results The ocurrence rate of deformity were 3.15% in this research. First three number of deformity were the central nervous system, .cardiovascular system, nonimmune hydrops fetalis( a-thalassemia ) respectively. Meanwhile we also found that fetus congenital structural eformity have specific ultrasound manifestation. some appearance are connected with the history of present illness or( and ) contacts or ( and ) age. Conclusion Ultrasonography may have an important and clinical significance for screening fetus congenital structural eformity.
