Quick answer
What is twin-to-twin transfusion syndrome?
Twin-to-twin transfusion syndrome, or TTTS, is a condition linked to twins who share a placenta. It involves unbalanced blood flow between the babies and is monitored by qualified maternity or fetal medicine teams. This article is for awareness only and should not delay contacting care.
NHS explains that TTTS affects twins who share a placenta and describes unbalanced blood flow. RCOG explains that monochorionic pregnancies share placental blood supply and may develop TTTS.
TTTS is one reason monochorionic twin pregnancies are watched closely. It is not something parents can diagnose from a general article, but it is a term worth recognizing if your babies share a placenta.
TwinPare takeaway
If your care team says the twins share a placenta, ask how TTTS screening works and what changes should prompt contact.
