title: Clinical relevance of sonographically estimated amniotic fluid volume: polyhydramnios.
abstract: Polyhydramnios is an excessive amount of amniotic fluid within the amniotic cavity. The etiology of polyhydramnios may be idiopathic, the consequence of fetal structural anomalies, or the consequence of various fetal and maternal conditions. The clinical importance of polyhydramnios is found in its association with adverse pregnancy outcomes and the risk of perinatal mortality. The antenatal management of polyhydramnios can be challenging as there are no formalized guidelines on the topic. The purpose of this review is to provide a literature-based overview on the subject of polyhydramnios in singleton pregnancies, demonstrate its clinical implications, and describe a practical approach to its management.
