Abstract:
Objective: The study was conducted to evaluate the value of transvaginal color Doppler ultrasonography of the uteroplacental circulation in predicting pregnancy outcome in women with threatened abortion during the first trimester of pregnancy. Design: Prospective study. Setting: Cairo University hospital. Subjects and Methods: 48 patients with threatened abortion of 7 to 11 weeks were prospectively evaluated. Transvaginal color Doppler ultrasonography was used to locate the retrochorionic arteries and to visualize blood flow within the intervillous space. Doppler shift spectra from the retrochorionic arteries were recorded and the resistive index (RI) of the retrochorionic vessels was calculated. If active blood flow was seen within the intervillous space it was located and recorded. Results: Abnormal color Doppler findings were associated with a significantly higher prevalence of abortion. The resistive index (RI) of the retrochorionic vessels was significantly higher in pregnancies ending in abortion. Also the presence of intervillous blood flow was significantly increased in gestational sac that end in miscarriage. Conclusion: Transvaginal color Doppler ultrasonography is an appropriate, non-invasive diagnostic method to evaluate the integrity of the uteroplacental circulation during early pregnancy. Abnormal color Doppler signals can be used to predict the outcome of first trimester gestations in women with threatened abortion. (author's)
