Umbilical cord compression
The umbilical cord sure is designed for durability and to cushion impact. Looking at the cords of monozygotic monoamnioticmonochorionic twins (known as momo twins) is an extreme example of this durability. This type of twins are very rare because they occur when both babies develop from one egg, share a placenta and are inside both layers of the water bag, the amnion and chorion, together. Momo twins account for only 1% of twin pregnancies. Sharing space so intimately comes with risks to the babies because their cords can become entangled and compressed while they play together. Very close prenatal monitoring is required and the babies are usually brought into the world via cesarean at around 32weeks to avoid the risks associated with cord compression. Fortunately both sets of twins were born alive and healthy! 📷•Medicogram•
