Sonography in early pregnancy: the significance of subchorionic hemorrhage.
Among 31 pregnant women with first-trimester bleeding, all were found on sonographic study to have subchorionic hemorrhage with a living fetus. Twenty-six went on to normal term pregnancies. Two had premature labor at 31 and 32 weeks. Three had first-trimester missed abortions. No correlation was found between volume of subchorionic bleeding and prognosis. The prognosis of the pregnancy in this group of 31 women with first-trimester bleeding and sonographic evidence of subchorionic hemorrhage and fetal cardiac activity was 80% favorable.
