Twin Reversed Arterial Perfusion Sequence (TRAP)

Twin reversed arterial perfusion (TRAP) sequence is a rare condition that occurs in pregnancies of identical twins that share a common placenta. Twins that share a placenta are known as monochorionic twins. This condition is considered a high-risk pregnancy that requires close monitoring by a skilled maternal-fetal medicine team.

The team at Fetal Care Center Dallas care for a high volume of monochorionic twin pregnancies each year. This experience helps to continuously expand our understanding of these complex pregnancies and our ability to differentiate between TRAP sequence and other conditions such as intrauterine growth restriction or twin-to-twin transfusion syndrome.
