OBJECTIVE: The clinical significance of subchorionic hematomas (SH) is debatable in the literature. The purpose of our study is to evaluate the outcomes of pregnancies complicated by SH in the first trimester. STUDY DESIGN: A retrospective case control study was performed using our ultrasound database to identify woman with or without SH during the first trimester. Outcome Variables included Preterm delivery (PTD), Preeclampsia (PEC), Growth restriction (IUGR), Meconium stained amniotic fluid(MSF) Non reassuring fetal heart tracing (NRFHT), Cesarean delivery (CD), Apgar and lt;7 at 5 minutes and NICU admission. RESULTS: A total of 770 patients were available for analysis. Demographics were similar among cases and controls. The rates of PTD (15.7% versus 6.1% p and lt;0.01), PEC (5.9% versus 1.8%, p and lt;0.01), CD rates (28.9% versus 21%, p = 0.02), NRFHT (6.9% versus 3.1 %, p =0.02) and MSF (10.8 versus 4.9%, p and lt; 0.01) were significantly higher in women with SH compared to those without SH. Women with SH were further subdivided into those with and without symptoms. The rate of adverse outcomes was higher in the symptomic group. CONCLUSION: The presence of SH in the first trimester is associated with adverse obstetrical outcome especially when symptomatic. These pregnancies warrant closer surveillance.
