{Which of the following is the most common form of placental abnormality:
 +
|type="()"}
 +
+ &nbsp; placenta accreta
 +
|| Correct! About 75-78% of cases with an abnormal adherence, with absence of decidua basalis. The incidence of {{placenta accreta}} also significantly increases in women with previous cesarean section compared to those without a prior surgical delivery.
 +
- &nbsp; placenta increta
 +
|| Incorrect! {{placenta increta}} represent about 17% of cases when the placenta attaches deep into the uterine wall and penetrates into the uterine muscle, but does not penetrate the uterine serosa. Placenta increta accounts for approximately 15-17% of all placental abnormality cases.
 +
- &nbsp; placenta percreta
 +
|| Incorrect! {{placenta percreta}} represent about 5% of placental abnormality cases with placental villi penetrate myometrium and through to uterine serosa.
 +
- &nbsp; vasa previa
 +
|| Incorrect! {{Vasa previa}} (vasa praevia) placental abnormality where the fetal vessels lie within the membranes close to or crossing the inner cervical os (opening) and generally diagnosed (98%) by {{ultrasound}}.
 +
 
 +

{Which of the following is the best description of a complete mole:
 +
|type="()"}
 +

 +

 +
+ &nbsp; chromosomal genetic material from the oocyte is lost, by an unknown process
 +

 +

 +
|| Incorrect!

+ &nbsp; an unbalanced blood flow from one twin to the other in utero
- &nbsp; is a primary inducer during organogenesis
+
|| Correct! {{twin–twin transfusion syndrome}} (TTTS) can occur in both monochorionic and diamniotic twins that results from an unbalanced blood flow from one to the other in utero. Monozygotic twin pregnancies carry a 10-20% risk of twin-twin transfusion syndrome.

- &nbsp; a balanced blood flow from one twin to the other in utero
|| The primitive streak is a site of migration of epiblast cells to form firstly endoderm and then the mesoderm.
+
|| Incorrect! {{twin–twin transfusion syndrome}} (TTTS) can occur in both monochorionic and diamniotic twins that results from an unbalanced blood flow from one to the other in utero. Monozygotic twin pregnancies carry a 10-20% risk of twin-twin transfusion syndrome.
