423例出生缺陷产前超声诊断效果分析

Correct diagnosis rrates and evalution of ultrasounds ulutrasonic diagnosis of birth defeccts

目的通过对423例出生缺陷儿资料回顾分析,探讨产前超声显像诊断效果及提高产前、产后诊断符合率的对策。方法筛查、登记2006.1-2010.1出生缺陷的423例将超声显像诊断与产后诊断符合率进行对比分析。结果产前超声显像出生缺陷的诊断与产后诊断总符合率为85.6%,符合率最高的神经管畸形,检出率最高的孕周为18-24周。结论产前的超声诊断出生缺陷多以结构畸形为主,超声软指标结合孕期血清标记以及定期规范的产前超声检查能进一步提高缺陷儿的检出率。

Objective： Through to 423 example birth defect material review analysis,the discussion pre-natal ultrasonoscopy diagnosis effect and enhances pre-natal,the post-natal diagnosis coincidence rate countermeasure.Methods： Screening,registers 2006.1-2010.1 birth defects 423 examples carries on the ultrasonoscopy diagnosis and the post-natal diagnosis coincidence rate the contrastive analysis.Results： The prenatal ultrasonoscopy birth defect＇s diagnosis and the post-natal diagnosis total coincidence rate is 85.6% ,the coincidence rate highest neural tube defect,the detection rate highest is pregnant the week is 18-24 weeks.Conclusion： Prenatal ultrasound diagnosis birth defect many by structure abnormal primarily,the supersonic soft target union gestation period blood serum mark as well as the regular standard＇s pre-natal supersonic inspection can further raise the flaw detection rate.
