Oligohydramnios Sequence: Causes, Symptoms & Treatment

Oligohydramnios sequence represents the description of the effects of insufficient amniotic fluid production. These are severe malformations that develop due to low amniotic fluid volumes during embryogenesis. The condition is fatal. What is an oligohydramnios sequence?
