ABSTRACT

Although monoamniotic twin pregnancies are uncommon, early detection is critical because complications are much more common than in diamniotic or dichorionic twin pregnancies. Only approximately 70% of monoamniotic twins survive. Furthermore, the high prevalence of foetal anomalies (15%- 25%), such as twin reversed arterial perfusion sequence and conjoined twinning, accounts for roughly half of all foetal deaths in these pregnancies. As a result, early anatomy screening during pregnancy's first trimester is advised. We present a case of a primigravida female with 35.3 weeks of gestation and a Rh-negative pregnancy who presented to the labour room with a fully dilated cervix and delivered twins, one foetus by breech presentation and another macerated twin. As a result, early detection, screening for foetal anomalies, monitoring for twin-twin transfusion syndrome, decisions about monitoring after viability and delivery timing and route are all critical and increased awareness is necessary, particularly in rural areas.
