Body
was changed:
A complete placenta praevia, also known as a type IV placenta praevia, is the most severe in terms of the placenta praevia spectrum. It is also the least likely to resolve with advancing gestation if detected in early pregnancy 1,3.
Pathology
In this situation, the placenta entirely covers the internal cervical os from one side to the other.
Treatment and prognosis
A complete praevia will require a caesarean section for delivery to avoid the risk of fetal and maternal haemorrhage.
