Is there any risk having a bi-lobed placenta if the connecting vessels aren crossing the cervix?
A bilobed placenta carries some risk even when the connecting vessels do not overlie the cervix. The connecting vessels may rupture. Velamentous insertion, even when not vasa previa (not overlying the cervix) is more frequently associated with fetal abnormalities and poor obstetric outcome. The risk is lower than with vasa previa, but still these patients may require more intensive monitoring.
