Pregnancy outcomes in severe polyhydramnios: no increase in risk in patients needing amnioreduction for maternal pain or respiratory distress.

Introduction: Polyhydramnios is a common complication of fetal malformations and has been described to have high risk of pregnancy complications such as prematurity and placental abruption. In a subgroup of women severe polyhydramnios may lead to maternal dyspnea or untreatable pain, and amnioreduction is the procedure indicated to relieve those symptoms. There is a lack of information concerning the increase in the risk for the pregnancy when the procedure is indicated.
