Which type of placenta pre is this?: (A) Type 4, (B) Type 2, (C) Type 1, (D) Type 3
Answer is B. Type 2 placenta is a placenta in the lower segment but not covering the os. A posterior type 2, as shown in this figure, is an indication to do a caesarean section as the fetal head can compress the placenta against the sacrum when the head is entering the pelvis. This can cause fetal hypoxia.
