目的探讨产前诊断对出生缺陷疾病诊断的临床意义,提高产前诊断率,降低出生缺陷发生率。方法通过孕期系统B超、产前筛查、染色体病产前诊断方法进行产前检查,分析2009年9月～2010年12月本院产前诊断的出生缺陷胎儿病例资料。结果 2549例孕妇通过系统B超、产前筛查、染色体病产前诊断等技术共诊断并引产缺陷胎儿31例,出生缺陷检出率为1.22%。结论通过产前超声检查、产前筛查技术、羊水染色体检查,及早地发现缺陷儿并及时终止妊娠,是减少出生缺陷发生的有效措施。
Objective To investigate the clinical significance of prenatal diagnosis in diagnosing birth defects, improve the rate of prenatal diagnosis and reduce the incidence of birth defects. Methods Prenatal diagnosis was made by prenatal diagnosis of B-prenatal screening, prenatal screening and chromosomal disease. The data of prenatal diagnosis of prenatal fetuses from September 2009 to December 2010 were analyzed. Results Totally 31 cases of 2549 pregnant women were diagnosed by abortion, prenatal screening and prenatal diagnosis of chromosomal diseases. The detection rate of birth defects was 1.22%. Conclusion Prenatal ultrasound, prenatal screening, amniotic fluid chromosome examination, early detection of defective children and timely termination of pregnancy are effective measures to reduce the incidence of birth defects.
