ABSTRACT
Objective To evaluate the value of prenatal ultrasonography in diagnosis of in vitro fertilization-embryo transfer (IVF-ET) fetal abnormalities during early trimester. Methods A total of 685 IVF-ET pregnant women received Doppler color ultrasound in our hospital during 11-13+6 weeks of pregnancy from January 2010 to December 2010; the number of fetal, polyembryony chorion, and gestational age were examined; and the abnormal structures were screened. Based on findings of sonographic markers, chorionic villi sampling was done for some fetals. Amniocentesis or selective reduction was done when triplet or one of the twins found with lethal abnormality. All the cases were followed up for pregnancy process and clinical results. Results Among the 685 IVF-ET pregnant women, 440 had singleton pregnancy (64. 23%), 244 had twin pregnancy (35. 62%), and only one had triplet pregnancy (0. 15%). Seven fetal abnormalities were detected in singleton pregnancies during early trimester, and five cases were clinically confirmed. Six fetal abnormalities were detected in twin pregnancies during early trimester, and three cases were clinically confirmed. Excluding the triplet pregnancy, the total incidence rate of abnormal fetal was 0. 86%(8/928), with two cases confirmed by chromosomal abnormality screening and two cases receiving selective reduction operation. Conclusion Standardized prenatal ultrasonography during early trimester(11-13+6 weeks) can improve the accurate screening rate of fetal abnormalities for IVF-ET pregnancy, and can help to deal with multiple pregnancy and abnormal fetals.
