+ | <quiz display=simple> | ||
{Which of the following is the most common form of placental abnormality: | |||
|type="()"} | |||
+ 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. | |||
- 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. | |||
- placenta percreta | |||
|| Incorrect! {{placenta percreta}} represent about 5% of placental abnormality cases with placental villi penetrate myometrium and through to uterine serosa. | |||
- 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: | |||

- three sets of chromosomes instead of the usual two | |||
|| Incorrect! | |||
+ chromosomal genetic material from the oocyte is lost, by an unknown process | |||
|| Correct! | |||
- triploidy of the genetic material | |||
|| Incorrect! | |||
- excess proliferation of the maternal decidua | |||
|| Incorrect! | |||
{ | {The condition "twin–twin transfusion syndrome" results from: | ||
|type="()"} | |type="()"} | ||
+ an unbalanced blood flow from one twin to the other in utero | |||
- | || 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. | ||
- a balanced blood flow from one twin to the other in utero | |||
|| | || 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. | ||
- | - direct connection of placental vein with placental artery | ||
- | || 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. | ||
- direct connection of placental arteries with placental vein | |||
|| 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. | |||
