When does twin to twin transfusion occur?

Twin-to-twin transfusion syndrome typically develops between weeks 16 and 26 of a woman’s pregnancy. But an ultrasound as early as 10 to 14 weeks can put doctors on alert that there is a twin gestation, and if they are sharing a placenta. TTTS is diagnosed by measuring levels of amniotic fluid.

What are the symptoms of twin to twin transfusion syndrome?

A mother whose twins have TTTS may experience:

• A sensation of the rapid growth of the womb.
• A uterus that measures large for dates.
• Abdominal pain, tightness, or contractions.
• A sudden increase in body weight.
• Swelling in the hands and legs in early pregnancy.

How does twin to twin transfusion happen?

Twin-to-twin transfusion syndrome (TTTS) is a rare pregnancy condition affecting identical twins or other multiples. TTTS occurs in pregnancies where twins share one placenta (afterbirth) and a network of blood vessels that supply oxygen and nutrients essential for development in the womb.

How is twin to twin transfusion treated?

Twin-twin transfusion syndrome can be treated with fetal laser photocoagulation (FLP), which selectively and sequentially ablates connections, depending on the type, to prevent the loss of one or both fetuses.

What is Stage 3 twin to twin transfusion syndrome?

Stage 3: The imbalance of blood flow starts to affect the heart function in one or both babies. This is seen in abnormal blood flow in the umbilical cords or hearts of the twins.

Does bed rest help TTTS?

Not all moms with TTTS are prescribed bed rest, but for those that are, bed rest means reducing their activity levels. For Nicole, being on bed rest didn’t mean she was taking it easy. After undergoing her laser procedure, she found ways to distract herself from counting the days until her babies reached 32 weeks.

What is the survival rate of twin to twin transfusion syndrome?

Purpose: Severe, progressive twin-to-twin transfusion syndrome (TTTS) is associated with near-100% mortality if left untreated. Endoscopic laser ablation of placental vessels (ELA) is associated with 75% to 80% survival of at least one twin.

How do you avoid twin to twin transfusions?

Many cases of TTTS can’t be prevented, but maintaining a healthy diet before and during pregnancy can help to prevent TTTS, or make it less severe if it does occur. Take prenatal supplements as recommended by your doctor. Always attend regular prenatal appointments to monitor your pregnancy.

What is the treatment for twin to twin transfusion?

Treatment of twin-to-twin transfusion syndrome generally involves repeated amniocentesis for the recipient twin, in order to keep the level of excess amniotic fluid down. Fetal laser surgery may be considered in some cases to sever the blood-vessel connection between the twins.

What is twin transfer syndrome?

Twin-twin transfusion syndrome (also called TTTS or twin to twin transfusion syndrome) is a condition in which the blood flows unequally between twins that share a placenta (monochorionic twins).

What is twin syndrome?

Twin-twin transfusion syndrome ( TTTS ) is a rare, serious condition that can occur in pregnancies when identical twins share a placenta. Abnormal blood vessel connections form in the placenta and allow blood to flow unevenly between the babies. One twin − called the donor – becomes dehydrated;
