Unequal Placental Sharing

Unequal Placental Sharing

Monochorionic twins have to share a single placenta but don’t always share it equally. Depending on where each fetus’ umbilical cord inserts into their shared placenta, one twin may get a smaller share of the nutrients and oxygen that are critical for normal growth and development. Perinatologist and twin expert, Dr. Larry Rand, describes the clinical markers of this condition and the importance of frequent ultrasound surveillance when monochorionic twins are found to be more than 20% different in size.
