Abstract

To investigate predictable ultrasonographic findings of early abortion. To investigate objective rules for the screening of abortion Ultrasonographic examination of 111 early pregnancies between the sixth and ninth week in women who had regular 28 day menstrual cycles was performed. Ultrasonographic measurements of the gestational sac. Crown rump length and fetal heart rate were performed using a linear array real time transducer with doppler ultrasonogram. All measurements of 17 early abortions were compared to those of 94 normal pregnancies. Most of early aborted pregnanices were classified correctly by disciminant analysis with G-SAC and CRL (GSAC=0.5 CRL+15. Sensitivity 76.5%, specificity 96.8%). With the addition of FHR, 94.1 of early abortions could be predicted. In conclusion, ultrasonographic findings of early intrauterine growth retardation. Small gestational sac and bradycardia can be predictable signs suggestive of poor prognosis of early pregnancies.
