Abstract

Monochorionic diamniotic twin pregnancies are prone to many complications which are unique to this type of twinning. These complications include twin twin transfusion and selective fetal growth restriction. However a rare complication of twinning is spontaneous septostomy of the dividing membrane. This converts the diamniotic pregnancy into a monoamniotic pregnancy with the added complication of cord entanglement which increases mortality and morbidity. A case report of this condition has been described and a detailed literature review performed.
