It is of clinical significance in asymptomatic patients at high risk for spontaneous delivery, and in patients with preterm labor and intact membranes. Subchorionic hematoma is another ultrasound finding that is associated with a higher incidence of threatened miscarriage and preterm delivery. We report two cases of occurrence of amniotic fluid sludge in patients with previously detected large subchorionic hematoma. In the first case subchorionic hematoma and amniotic fluid sludge were detected by ultrasonography at 13 + 1 and 18 + 6 weeks' gestation, respectively, followed by preterm premature rupture of membranes, placental abruption and emergency Cesarean section. In the second case subchorionic hematoma and amniotic fluid sludge were detected by ultrasound at 11 + 3 and 15 + 5 weeks' gestation, respectively, followed by miscarriage with histological chorioamnionitis. The coincidence of subchorionic hematoma and amniotic fluid sludge in these cases points to a possible connection between these two significant ultrasound findings. Copyright \u00a9 2009 ISUOG.
