PRENATAL ULTRASOUND DIAGNOSIS OF MASSIVE SUBCHORIONIC THROMBOHEMATOMA

Massive subchorionic thrombohematoma is a rare condition in which a la rge material blood clot separates the chorionic elate from the villous chorion. This condition is usually complicated by intrauterine growth restriction, and is often associated with fetal distress and perinata l death. We present a case in which the diagnosis of massive subchorio nic thrombohematoma, was made of 24 weeks' gestation. Doppler ultrasou nd helped to confirm the diagnosis and demonstrated severely abnormal umbilical blood flow. Two days after the diagnosis, fetal distress pro mpted emergency Cesarean delivery of a growth-restricted infant.
