Twin to twin transfusion syndrome

Twin to twin transfusion syndrome (TTTS) is a rare condition that occurs during a twin pregnancy when blood moves from one twin (the “donor twin”) to the other (the “recipient twin”) while in the womb. TTTS is a complication that specifically occurs in identical (monozygotic) twin pregnancies that share the same “egg” sac (monochorionic) that may or may not share the same amniotic sac (monoamniotic). TTTS usually develops between 15 and 26 weeks of pregnancy. The donor twin may be born smaller, with paleness, anemia, and dehydration. The recipient twin may be born larger, with redness, too much blood, and increased blood pressure, resulting in an increased risk for heart failure. Treatment may require repeated amniocentesis during pregnancy. Fetal laser surgery may be done to interrupt the flow of blood from one twin to the other. After birth, treatment depends on the infant’s specific symptoms. The donor twin may need a blood transfusion to treat anemia. The recipient twin may need to have the volume of body fluid reduced. This may involve an exchange transfusion. Medications may be given to treat heart failure in the recipient twin, per the U.S. Department of Health and Human Services/National Institutes of Health

Approximately 15% of Identical Twin pregnancies develop TTTS.

Research with multiples contributes to our knowledge of issues relevant specifically to multiples but also has the potential to contribute transformative insights to our understanding of health and disease for the whole population. ICOMBO is gathering information to present to researchers about what multiples (and their families) would like if they are involved in research. The first step is a survey to find out more detailed information about how people feel about being involved in research. It is important that we can get the message to researchers about how we want multiples to be treated, so your input will be very valuable. I know some of the questions may seem a bit odd to those not familiar with what some research studies involve. However, these will help us guide researchers on what we may accept when asked to participate and then they can design their studies accordingly. 

This survey is for both multiples themselves (if they are old enough to make decisions about their involvement in research) and parents of younger multiples.

If possible please complete the survey in English using the following link:

Alternatively the survey is available in a number of other language options if you would prefer:

Arabic –

French –

German –

Japanese –

Spanish –

Note all your responses are anonymous.

Please share far and wide so we can get as many responses as possible. If you have any questions about this survey please contact Carolyn ( Thank you.

ICOMBO stands for the International Council of Multiple Birth Organisations. We are a voluntary organisation whose aim is to raise awareness of the unique needs of multiple-birth infants, children, adults and their families promoting their health, education and welfare.

Monochorionic Twin Pregnancy Survey









Evergreen Fetal Therapy and Center for Fetal Medicine and Women’s Ultrasound/UCLA are conducting an anonymous survey on women who have been pregnant with monochorionic twins. Monochorionic twins are identical twins and higher order multiples who shared a placenta. Please help us learn more about monochorionic twins and multiples and how they are screened and treated for possible complications (Twin-Twin Transfusion Syndrome (TTTS), Twin Anemia Polycythemia Sequence (TAPS) and other pregnancy complications). You will also help us learn how they are being managed across the United States and the world.

Thank you for participating and for improving awareness of and treatment for monochorionic pregnancies!
