Abstract
Early fetal growth delay and early oligohydramnios have been suspected as signs of embryonal jeopardy. Sonographic examinations of 100 early pregnancies between the sixth and ninth gestational week were performed to investigate predictable sonographic findings of early abortion. Sonographic measurements of the gestational sac (G‐SAC), Crown‐rump length (CRL) and fetal heart rate (FHR) were performed using a transvaginal transducer with Doppler. All measurement of 11 early abortions were compared to those of 89 normal pregnancies to investigate the objective rules for the screening of early abortion. Most of the early aborted pregnancies were classified correctly by discriminant analysis with G‐SAC and CRL (G‐SAC = 0.5222 × CRL + 14.6673 = 0.5 × CRL + 15). In conclusion, early fetal growth retardation and oligohydramnios could discriminate the poor prognosis of early pregnancies.
