Twin-twin transfusion syndrome
Twin-twin transfusion syndrome (TTTS) is a problem where one fetus — the donor twin — pumps blood to the other fetus — the recipient twin.
- Without intervention, the recipient twin receives too much blood and may develop fluid overload, heart failure and die, and the donor twin may die from not having enough blood, or severe anemia.
- Almost all identical twins exchange blood across the placenta, although usually the exchange is balanced.
- In TTTS, the blood connections in the placenta are abnormal and the blood passes unequally between the two fetuses.
TTTS occurs in varying stages of severity, which may or may not progress to the point where intervention is needed.
Leading the way in fetal care
Through the joint work of researchers, genetic specialists, surgeons and other care providers, Boston Children's Hospital's Advanced Fetal Care Center is breaking new ground in understanding and successfully treating a wide variety of fetal health concerns, including TTTS.
