Twin-to-twin transfusion syndrome
Twin-to-twin transfusion syndrome
Twin-to-twin transfusion syndrome (TTTS, also known as Feto-Fetal Transfusion Syndrome and Twin Oligohydramnios-Polyhydramnios Sequence) is a complication that can occur in pregnancies involving identical twins or other multiples. It is a condition in which the blood vessels of the babies' shared placenta are connected. This can lead to one twin receiving too much blood, while the other receives too little.
Pronunciation
Twin-to-twin transfusion syndrome: /ˈtwɪn tə ˈtwɪn trænsˈfjuːʒən sɪnˈdroʊm/
Etymology
The term "twin-to-twin transfusion syndrome" is derived from the nature of the condition itself. It refers to the transfusion of blood from one twin (the 'donor') to the other (the 'recipient') through shared blood vessels in the placenta.
Symptoms and Diagnosis
The symptoms of TTTS can vary depending on the severity of the condition. The donor twin may be smaller, have less amniotic fluid and can suffer from anemia. The recipient twin may have too much amniotic fluid and can develop heart failure due to the volume of extra blood. Diagnosis is usually made through ultrasound during pregnancy.
Treatment
Treatment options for TTTS include amnioreduction, laser coagulation of the shared blood vessels, and in severe cases, fetal surgery. The choice of treatment depends on the severity of the condition and the stage of pregnancy.
