Objective To investigate the implementation of the system of older pregnant women prenatal ultrasound screening for the diagnosis and clinioal significance.Methods Clinical data from March 2004 to April 2009 a total of 10 630 cases of pregnant women receiving prenatal ultrasound examination of fetal malformation data,of which 712 cases of advanced maternal age( expected date of birth aged≥35 years) to implement the system of prenatal ultrasound screening and follow-up of all maternal age pregnancy outcome,the final post-natal diagnosis of fetal malformations in the standard,both young women screened as a control group for comparison to assess the value of prenatal ultrasound diagnosis.Results 712 cases of advanced maternal age,prenatal ultrasound diagnosis of fetal malformations in 32 cases,abnormalities occur in approximately 4.49%,single abnormal in 15 cases,complex deformity in 17 cases,missed 4 cases of malformation detection rate was 88.88% (36/32).Control group,9918 cases of prenatal ultrasound diagnosis of fetal malformations 243 cases,2.45% incidence of deformity (243/9 918 ).Conclusion Older pregnant women,prenatal ultrasound screening for malformations occur in approximately 4.49%,higher than the detection rate with screening younger women 2.45%,of older pregnant women according to the results of prenatal diagnostic screening could be effective in reducing the birth rate of deformed children and the rate of misdiagnosis.
