Transabdominal amnioinfusion in the correction of oligohydramnios following twin-to-singleton reduction – A report of two cases

Abstract

Background: On rare occasions, elective iatrogenic reduction of a dichorionic twin is performed due to maternal request and in order to improve the perinatal outcome. Materials and methods: Nine twin-to-singleton reductions were identified retrospectively at the Feto-maternal Unit, University of Szeged, Hungary, between December 1997 and June 2015. A post-procedure, routine weekly sonographic scan revealed severe oligohydramnios in two out of the nine cases (22.2%) and amnioinfusion was performed in the mid-trimester to prolong gestation. The fetus survived in one case (11.1%) and the pregnancy continued until preterm birth. Conclusion: A repeated sonographic follow-up for an early diagnosis of oligohydramnios is feasible to avoid miscarriage after artificial embryo reduction.
