Blood flow differences in twin pregnancy complications
Part of Brain & nervous system, Women’s health & pregnancy clinical trials.
This study looks at whether a difference in blood flow measurements between the two babies (called the cerebroplacental ratio) at 16-20 weeks can help predict complications in twin pregnancies where the babies share a placenta. It may help doctors identify which twins need extra monitoring.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older and can give consent.
- You are pregnant with twins that share one placenta but have separate sacs (monochorionic diamniotic).
- An ultrasound between 16 and 20 weeks showed that the blood flow to each baby's brain is different (discordant cerebroplacental ratio).
- Neither baby has a major birth defect or chromosome problem.
- You have not already been diagnosed with twin-to-twin transfusion syndrome, twin anemia polycythemia sequence, or selective growth restriction.

Other trials that look related to this one.
This study uses special ultrasound scans to look at the placenta (the organ that feeds your babies) in twin pregnancies where the babies share one placenta. The goal is to learn more about how these placentas work, which might help improve care for future moms and babies.
This trial studies the placentas of identical (monochorionic) twin pregnancies to learn more about their structure and health. Participation involves donating the placenta after birth for analysis.
This study looks at blood flow in a specific part of the fetal heart (the aortic isthmus) in babies who are growing slowly in the womb (fetal growth restriction). It aims to see how this blood flow changes and relates to other monitoring measurements, which may help doctors better understand and manage this condition.
This study looks at babies in monochorionic (shared-placenta) twin pregnancies where one or both babies are growing too slowly. It aims to better understand this condition and follow families over time to improve care, with check-ins through age 2 after birth.
This trial uses an MRI scan to look at placental health in pregnancies where the baby (or one twin) is not growing as expected. The goal is to better understand placental problems and how they may affect baby growth.
This study looks at how blood flow measurements (Doppler) in the baby's ductus venosus (a small blood vessel near the heart) relate to pregnancy outcomes, especially for babies who are smaller than expected. If you join, researchers will track these measurements and your baby's health to see if they can predict better or worse outcomes.
