Twin-Twin Transfusion Syndrome (TTTS)
Twin-twin transfusion syndrome (TTTS) is a condition in which the blood passes unequally between twins that share a placenta. The smaller twin (donor) pumps blood to the larger twin (recipient). Without intervention, the condition can be fatal for both twins. Accurate diagnosis is extremely important in distinguishing TTTS from other related anomalies, such as selective intrauterine growth restriction (sIUGR). The Center for Fetal Diagnosis and Treatment at CHOP manages pregnancies diagnosed with these conditions and offers a variety of treatment options, including fetal surgery.
