[Management of mono-amnion twin pregnancy]

There have been only a few reports on monoamniotic twin pregnancies from the period of modern perinatology. Consequently, available recommendations about the management of these high-risk pregnancies are uncertain. In this study, we present the management and the outcome of three monoamniotic twin pregnancies and two further pregnancies with acardiac acephalus twin in comparison to other case reports and case series from the literature. Practical ways of caring for these high-risk pregnancies are outlined, emphasising the continuous search for entanglement of umbilical cord by ultrasound and cardiotocography. The special importance of intensified cardiotocographic monitoring is demonstrated.
