Our objective was to prospectively validate the use of gestational sac GS , yolk sac YS diameter, crown-rump length CRL , and embryonal heart rate HR dimensions to identify early pregnancy loss.

This was a prospective cohort study of first trimester pregnancies. Non-parametric tests and logistic regression models were used for comparisons of distributions and testing of associations. A total of patients were included, of which were singleton pregnancies, 51 were twins, and 2 were triplets total fetuses. Fifty-two patients had 61 losses. We built nomograms with the changes of the parameters evaluated in ongoing, as well as in pregnancy loss. The YS reliably identified the occurrence of a miscarriage at least 7 days prior its occurrence.

CRL and HR became abnormal at a later time in pregnancy and closer to the event.
