The risk of complications depends on the chorionicity, with the prognosis worst for mono-mono and best for di-di:. Monochorionic twin pregnancies share the one placenta and are therefore prone to hemodynamic complications such as:.

Conjoined twins occur only in monoamniotic pregnancies. The role of ultrasound is crucial adequate in the monitoring of the pregnancy and planning for delivery.
The number of fetuses and their chorionicity and amnionicity must be determined, as well as monitoring for complications and anomalies.
