[Prognostic value of the data of ultrasonographic diagnosis of uterine hemorrhage during pregnancy in patients with threatened abortion].

Ultrasonographic follow-up of 240 pregnant women with congenital and acquired uterine malformations in 135 (56.3%) of them has detected bleedings at various gestational dates. Ultrasonographic correlates of bleedings were ascertained. Bleedings proved to be a significant determinant of outcome. Profuse transient bleedings were associated with a 2-3-fold higher risk of spontaneous abortion and premature delivery while longer and scarce bleedings correlated with a higher incidence of ++non-progressing pregnancy. A low placenta insertion was found in 50-65% of the patients. This evidence indicates a need for early identification of pregnancies with low placenta insertion in order to prevent bleedings. Ultrasonography is essential for appropriate hemostatic and corrective therapy.
