Conditions associated with polyhydramnios[1-4]

Conditions associated with polyhydramnios[1-4]
Idiopathic
Fetal structural anomaly that impedes swallowing
  • Primary gastrointestinal obstruction (eg, esophageal or duodenal atresia)
  • Secondary gastrointestinal obstruction (eg, congenital diaphragmatic hernia, cervical or thoracic mass)
  • Craniofacial abnormality (eg, cleft lip/palate, facial tumor [eg, oropharyngeal teratoma], micrognathia)
Fetal neuromuscular disorder that impedes swallowing (eg, myotonic dystrophy, anencephaly)
Genetic syndromes
  • Trisomy 18 or 21
  • Prader-Willi
  • Bartter
  • Beckwith-Wiedemann
  • RASopathy (eg, Noonan syndrome, cardiofaciocutaneous syndrome, Costello syndrome, capillary malformation-arteriovenous malformation, and neurofibromatosis type 1)
High fetal cardiac output state
  • Supraventricular tachycardia
  • Severe anemia (eg, alloimmunization, viral infection [Parvovirus B19, cytomegalovirus], hemoglobinopathy)
  • Fetal or placental mass with arteriovenous shunt (eg, sacrococcygeal teratoma, large chorioangioma)
Twin-twin transfusion syndrome
Maternal diabetes mellitus
Macrosomia
Hydrops fetalis
Some of these conditions overlap. For example, polyhydramnios in trisomy 21 is due to duodenal atresia or other blockage in the gastrointestinal tract.
