The effect of vaginal bleeding and non-spesific pelvic pain on pregnancy outcomes in subchorionic hematomas cases.

Objectives: To determine the clinical differences and factors affecting early pregnancy outcome in the first and early secondtrimester subchorionic hematoma cases.

Material And Methods: This study involved with the retrospective analysis and evaluation of 81 cases diagnosed withsubchorionic hematoma. The patients were grouped according to the gestational periods, symptoms at the time of admission,ratio of surrounding hematoma to the gestational sac, and whether there was a pregnancy loss. The groups werecompared according to the clinical features and pregnancy outcomes.

Results: The ratio of surrounding hematoma to the gestational sac in the group with pregnancy loss was significantly higher(p = 0.002). When the cut-off value was 35.5%, it could determine the possibility of a complication in pregnancy with 70%sensitivity and 75% specificity. Nonspecific pelvic pain were significantly higher in the pregnancy loss group than in theother group. Logistic regression analysis was performed to determine the effect of these two parameters on the pregnancyoutcome. Although the presence of non-specific pelvic pain is more in the group with pregnancy loss; there was no effectof on pregnancy outcome (p = 0.141). The risk of pregnancy loss increased 4.5 fold if the ratio of ScH to gestational sacwas above 35% (p = 0.027).

Conclusions: In the cases of subchorionic hematoma, we concluded that when the ratio of surrounding hematoma tothe gestational sac increased and when it was accompanied by nonspecific pelvic pain, the hospitalization period of thepatients increased and the ratio of pregnancy loss was higher.
