How serious is TTTS?
Twin-twin transfusion syndrome (TTTS) is a rare, serious condition that can occur in pregnancies. This happens when identical twins share a placenta (monochorionic). Abnormal blood vessel connections form in the placenta. They allow blood to flow unevenly between the fetuses.
What is the survival rate of TTTS?
The majority of TTTS twins who have appropriate treatment during pregnancy will survive and the majority of survivors will be normal and healthy. If untreated, the survival rate for TTTS twins is approximately 10 to 15 percent. Once TTTS babies are born, blood supply sharing is no longer a factor.
What are the symptoms of TTTS?
What are the Warning Signs of TTTS?
- The sensation of a rapid growth of the womb.
- A uterus that measures large for dates.
- Abdominal pain or tightness, or uterine contractions.
- Sudden increases in body weight.
- Hand and leg swelling 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 quickly does TTTS progress?
Results: Among 132 consecutive cases of TTTS, 46 women presented with Stage I disease. In the majority (69.6%), disease remained stable (28.3%) or regressed (41.3%). Of cases that progressed, 79% did so within 2 weeks and 93% progressed to at least Stage III.
Can twins survive TTTS?
Prognosis. The majority of twins with TTTS who have appropriate treatment during pregnancy will survive and the majority of survivors will be normal and healthy. The survival of both twins is very important to us.
How is TTTS diagnosed?
TTTS is diagnosed by measuring levels of amniotic fluid. If one twin has a high level of amniotic fluid in the amniotic sac and the other twin has a low level, it will be visible via ultrasound.
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 Twinless twin syndrome?
Vanishing twin syndrome was first recognized in 1945. This occurs when a twin or multiple disappears in the uterus during pregnancy as a result of a miscarriage of one twin or multiple. The fetal tissue is absorbed by the other twin, multiple, placenta or the mother. This gives the appearance of a “vanishing twin.”
