Monochorionic – Monoamniotic Twins’ Placenta

Abstract

A 33-year-old healthy primigravida with a body mass indexof 21 kg/m², unexplained infertility, pregnancy after IVF, and single embryo transfer, was referred to our department at 12 weeks. We diagnosed monochorionic – monoamniotic twin pregnancy with normal growth, anatomy, and dopplers in both fetuses, anterior normal appearing placenta with eccentric insertion of both umbilical cords, and cervical length of 40 mm. After extensive counseling on the risks and complications of monochorionic – monoamniotic twins, the parents decided to continue with the pregnancy. The course of the pregnancy was uneventful for the mother and fetuses with normal results on all biweekly performed ultrasound examinations. At 30 weeks she received corticosteroids for fetal lung maturation.
