PREDICTING PREGNANCY SURVIVAL FROM A SINGLE 1ST TRIMESTER VAGINAL ULTRASONOGRAM

This retrospective study evaluates early first trimester FHR, gestatio nal SACD, and CRL measurements as means to predict ultimate pregnancy outcome. Outcomes of 274 pregnancies were monitored a single time by t ransvaginal ultrasonography with measurements recorded between 5.0 and 9.0 weeks' gestation. The measurements were then correlated with the pregnancy outcomes. FHR (P < 0.0001), gestational SACD (P = 0.0002), a nd CRL (P = 0.0059) each correlated positively with a successful pregn ancy outcome. Measurements from a single transvaginal ultrasonogram ca n be used to predict a successful pregnancy outcome in the early first trimester.
