title: Intrathoracic displacement of pleuroamniotic shunt after successful in utero treatment of fetal hydrops secondary to hydrothorax. Case report and review of the literature.
abstract: BACKGROUND
  Primary fetal pleural effusion can be associated with high perinatal morbidity and mortality, especially when it is associated with the presence of fetal hydrops. Pleuroamniotic shunting results in effective drainage and lung expansion which prolong the pregnancy and improve neonatal survival. Intrathoracic displacement of the shunt is a rare but a known complication of shunt insertion and can cause some infant morbidity. We present a case of successful antenatal treatment of primary fetal pleural effusion complicated with intrathoracic displacement of the shunt without any fetal and long-term infant morbidity.
  
  
  METHODS
  Our case presented with severe bilateral fetal pleural effusion, causing fetal hydrops treated successfully by pleuroamniotic shunting at 25 weeks of gestation which was complicated by dislodgement of the shunt into the fetal chest documented by antenatal ultrasound at 30 weeks. There was no recurrence of fetal pleural effusion or other antenatal complication. After delivery there were no postnatal complications, so removal of the shunt was not considered, and clinical follow-up of the infant to the age of 12 months was uneventful.
  
  
  CONCLUSIONS
  The complication of intrathoracic displacement of a pleuroamniotic shunt can be recognized antenatally by ultrasound. Since there are no postnatal pulmonary complications related to the presence of the shunt inside the infant chest, conservative management in these cases appears to be a safe approach.
