Multifetal Preganancy Flashcards
(10 cards)
most common fetal complication of multifetal gestation,?
**Prematurity
*present in 25% of twin pregnancies,
*50% in triple pregnancies,
* 75% in quadruple
pregnancies
Dizygotic twins
*arise from multiple ovulation with two zygotes.
They are always Di-chorionic, Di-amniontic
.Monozygotic twins
arise from one zygote
Twin-Twin Transfusion syndrome
*In Mono-chorionic gestation.
*Donor Vs Recipient.
-The twins share a single placenta but do so unequally less blood supply,
** resulting in donor :
#growth restriction
#oligohydramnios
#anemia.
**recipient:
#excessive growth
#polyhydramnios
#polycythemia.
#more risk to die
Twin-Twin Transfusion syndrome treatment :
laser therapy
Di-chorionic, Di-amniotic
two placenta and two sacs
{delivery at 37+ week} (vaginal)
Mono-chorionic, Di-amniotic
one placenta and two sacs.
{delivery at 36-37 week} (vaginal)
Mono-chorionic, Mono-amniotic
one placenta and one sac.
{delivery by CS at 32-34 week due to risk of cord entanglement

monochorionic monoamniotic twins
