Monitoring cognitive disturbance in delirium with the ten-point clock test

Isolated bilateral pleural effusion with mediastinal compression leading to hydropic change of the fetus is unusual, and carries a high risk of perinatal death. This condition can be reversed in utero by performing ultrasound-guided shunting surgery. We describe a hydropic fetus at 30 weeks' gestation with rapid recurrence of pleural effusion after thoracentesis. The pleural effusion and hydrops resolved within 1 week after ultrasound-guided thoracoamniotic shunt and the fetal lungs were restored to their normal size. The fetus was born at 35 weeks' gestation and had an uneventful postnatal course. The technique of restoring cardiopulmonary function in utero through intrathoracic decompression offers a valuable alternative to repetitive prenatal thoracentesis or preterm delivery of fetuses with hydrops caused by bilateral pleural effusion.
