Introduction: Threatened abortion is defined by the World Health Organization (WHO) as bloody vaginal discharge or frank bleeding through the cervical os during the first half of pregnancy without cervical dilatation. Incidence of threatened abortion is 16 to 25 % in pregnancy. Subchorionic bleeding (Also known as a subchorionic hematoma) is accumulation of blood within the folds of the chorion. Incidence of intrauterine hemorrhage is 4 to 22% in threatened abortions. Purpose of the study is to know the magnitude of sub chorionic hemorrhage in threatened abortions.
Aims and Objectives: Correlate between number of patients who had threatened abortion and subchorionic hemorrhage on scan and to obtain magnitude by a retrospective study conducted between October 2018 to October 2019.
Materials and Methods: This retrospective study was performed in the Department of Obstetrics and Gynecology in KIMSH and data was collected from case records retrieved from medical record section over 1year period from October 2018 to October 2019. Case selection done based on inclusion and exclusion criteria. Each patient’s case record was analyzed with regard to age, parity, antenatal history, symptoms, clinical signs and scan report.
Results: The incidence of subchorionic hemorrhage in threatened abortion in our study was 65.6 %.Out of 32 cases of threatened abortions over a year, scans of 21cases showed varying amount of subchorionic hemorrhage. Out of 21 cases, 16 cases continued pregnancy and 5 cases had large amount of subchorionic hemorrhage who progressed to spontaneous abortion
Conclusion: Hence this study shows subchorionic hemorrhage has been a consistent USG finding in Threatened abortion and also that larger subchorionic hemorrhage has a poor outcome, leading to miscarriage.
