Predicting pregnancy survival from a single first trimester vaginal ultrasonogram.
This retrospective study evaluates early first trimester FHR, gestational SACD, and CRL measurements as means to predict ultimate pregnancy outcome. Outcomes of 274 pregnancies were monitored a single time by transvaginal 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), and CRL (P = 0.0059) each correlated positively with a successful pregnancy outcome. Measurements from a single transvaginal ultrasonogram can be used to predict a successful pregnancy outcome in the early first trimester.
