First trimester vaginal bleeding is an early indicator of underlying placental pathology and is a causative factor for adverse perinatal outcome. The presence of subchorionic hemorrhage is associated with 4-33% rate of miscarriage, but nothing conclusive has been repoted about the outcomes of subchorionic hematomas in the ongoing pregnancies. So we aimed to study the outcome in pregnancies with subchorionic hemorrhage presenting with vaginal bleeding in up to 20 weeks of pregnancy.
The present study was an Observational study conducted over a period of one year. A sample size of 230 patients presenting with threatened abortion within 20 weeks of gestation and who fulfilled the inclusion criteria were recruited in the study. A routine ultrasound examination was done to look for presence of subchorionic hemorrhage and outcomes of such pregnancies were studied.
Total 230 subjects presented with bleeding in early pregnancy with gestational age less than 20 weeks On ultrasound examination,31(13.4%) patients were found to have subchorionic hemorrhage . The current study showed that women with sub chorionic haematoma had significantly higher rate of complications .
There is an increased risk of adverse outcome in pregnancy with subchorionic hemorrhage.
