Abstract

Objective The aim of this study is to investigate the relationship between first trimester subchorionic hematomas and pregnancy outcomes in women with singleton pregnancies.

Material and methods Between January 2018 and January 2019, patients who had a single pregnancy between the 6th and 14th weeks of their pregnancy and were hospitalized with the diagnosis of abortus imminens in the early pregnancy service were included in the study. According to the ultrasonographic examination, those with subchorionic hematoma and those with no hematoma were compared in terms of demographic data, pregnancy outcomes and pregnancy complications.

Results 400 abortus immines cases with subchorionic hematoma and 400 abortus imminens cases without subchorionic hematoma were compared. Preterm delivery percentages were similar in both groups, however abortus percentage was significantly higher in the hematoma group (34.2 vs. 24.7%; p=0.007). In addition, it was revealed that the presence of subchorionic hematoma before the 20th gestational week increased the risk of miscarriage 1.58 times. However, no data could be found in the study that could correlate the size of the hematoma with pregnancy loss.

Conclusion The presence of subchorionic hematoma increases abortion rates in abortus imminens cases. And the presence of subchorionic hematoma in cases with ongoing pregnancy does not increase the complications of delivery.

Key words

abortion - subchorionic hematoma - ultrasonography - threatened miscarriage - pregnancy outcomes
