Oligohydramnios: A review of etiology and management options

Abstract

Oligohydramnios is both a consequence of fetal malformations and of uteroplacental insufficiency. Its existence is associated with a high rate of both antepartum and intrapartum complications. It is vital that its occurrence is detected as early as possible so that we can manage it correctly. The main causes of its occurrence are identified and described in this review. The management of oligohydramnios is most often expectant, the timing of delivery also being determined by Doppler examination and changes in parameters measuring fetal growth and development.
