What is twin to twin transfusion syndrome?
•A rare, in-utero condition involving an imbalance in blood flow between identical twins. •Symptoms include an imbalance in amniotic fluid between twins while in the womb.
What is Monochorionic Diamniotic twin pregnancy?
Monochorionic diamniotic (Mo-Di) twins are twins that share a placenta and therefore a blood supply. They occur in 3–4 per 1,000 pregnancies. They are not the type of twins that run in families. The only known risk factor is in vitro fertilization (IVF).
What is TTTS laser surgery?
TTTS laser surgery is performed to seal off the abnormal blood vessel connections, stop the harmful sharing of fluids and correct or prevent complications. In the most severe cases of twin-twin transfusion, the survival rate can be as low as 10 to 15% if left untreated.
When do you deliver monochorionic Diamniotic twins?
Time of delivery in monochorionic pregnancies Most specialists in large reference centers recommend delivery of monochorionic/diamniotic twins between 36 + 0 and 36 + 6 weeks. This may be the point of balance between the already reduced risk of prematurity and the risk of fetal death [9].
Does TTTS affect the mother?
Left untreated, TTTS will often worsen. The recipient tries to deal with excess fluid by creating more and more amniotic fluid – this will overstretch the uterus. This may cause the mother discomfort and may put pressure on the cervix, the lower part of the uterus.
Do twins always skip a generation?
It’s a common misconception that twins skip a generation in families. There is absolutely no evidence, other than circumstantial, that twins are more likely to occur every other generation.
What is twin to twin transfusion syndrome (TTTS)?
Twin-to-twin transfusion syndrome (TTTS), also known as feto-fetal transfusion syndrome (FFTS), twin oligohydramnios-polyhydramnios sequence (TOPS) and stuck twin syndrome is a complication of disproportionate blood supply, resulting in high morbidity and mortality.
What is the prevalence of TTTS in identical twins?
The majority of identical twins share a common (monochorionic) placenta, and of these approximately 15% go on to develop TTTS.
What is tonic tensor tympani syndrome (TTTS)?
For Tonic tensor tympani syndrome, see Tensor tympani muscle. Twin-to-twin transfusion syndrome ( TTTS ), also known as feto-fetal transfusion syndrome ( FFTS ), twin oligohydramnios-polyhydramnios sequence ( TOPS) and stuck twin syndrome is a complication of disproportionate blood supply, resulting in high morbidity and mortality.
Can TTTS be fatal?
TTTS is potentially lethal to either or both twins, no matter when it is detected. However, when detected past week 25, emergency delivery may be considered to rescue the babies if the TTTS is severe. Other than requiring a monochorionic twin (or higher multiple) pregnancy, the underlying causes of TTTS are not known.
