There are three types of vasa previa. Types 1 and 2 were described by Catanzarite et al. In Type 1, there is a velamentous insertion with vessels running over the cervix. In Type 2, unprotected vessels run between lobes of a bilobed or succenturiate lobed placenta. In Type 3, a portion of the placenta overlying the cervix undergoes atrophy.
1 Placenta previa is more common early in pregnancy and might resolve as the uterus grows. 2  Placenta previa can cause severe vaginal bleeding before or during delivery. 3  A C-section delivery usually is required if the placenta previa is present at the time of delivery.
