A twin pregnancy can mean twice the excitement and twice the fun for a mom-to-be. After all, what can be better than welcoming two bundles of joy? Unfortunately, twin pregnancies can also be quite challenging at times, causing twice the morning sickness and twice the fatigue. It can also be particularly stressful if your twins happen to be monoamniotic. Monoamniotic twins are quite rare, but require special care and monitoring. Here is some essential information if you are expecting monoamniotic twins.What are Monoamniotic Twins? Monoamniotic twins are identical twins that develop inside the same amniotic sac. Also known as MoMo twins (Monoamniotic-Monochorionic), monoamniotic twins are always identical. These share a placenta within their mother’s uterus, but have two separate umbilical cords for nourishment. Monoamniotic twins are rare, occurring in approximately 1 in 35,000 to 1 in 60,000 pregnancies. Monoamniotic triplets can also develop, but this is extremely rare. Unfortunately, monoamniotic twins are at great risk for health complications due to the close proximity of the two umbilical cords in the amniotic sac. This makes it particularly easy for the twins to become entangled in each other’s cords, or to compress one another’s cords, endangering their oxygen and food supply. The survival rate for monoamniotic twins is approximately 50% though is now higher due to better technology and equipment. Complications Associated with Monoamniotic Twins Unfortunately, monoamniotic twins face a lot of potential health hazards throughout pregnancy. Many of these can be life threatening, so it is important to make sure that you receive specialized care if you are experiencing this type of twin pregnancy. Possible complications include: Cord Entanglement: Cord entanglement is one of the main complications associated with monoamniotic twins. Because the twins have no amniotic membrane separating them, their umbilical cords can easily become entangled. This can hinder fetal movement and development. Additionally, if the twins become tied together in the uterus, one twin may become stuck in the birth canal during labor and delivery, which can be life threatening. Cord entanglement happens to some degree in almost all monoamniotic pregnancies. Cord Compression: Cord compression is another life threatening condition common in monoamniotic twins. As the twins move around in the amniotic sac, it is possible that one will compress the other’s umbilical cord. This can prevent vital nutrients and blood from traveling to the other baby, resulting in fetal death. Twin-to-Twin Transfusion Syndrome (TTTS): Twin-to-twin transfusion syndrome can occur in monoamniotic twins. This syndrome happens when one twin receives the majority of the nourishment in the womb, causing the other twin to become undernourished and sickly. Typically, TTTS is diagnosed by examining fluid levels in the two amniotic sacs. But because monoamniotic twins only have one amniotic sac, diagnosis of TTTS is much more difficult. Diagnosis rests on comparing the physical development of both of the twins. Preterm Birth: All monoamniotic twins are born premature. This is because full-term pregnancy is deemed unsafe by most medical professionals. The risk for cord entanglement and compression simply becomes too great after 34 weeks. For this reason, all monoamniotic twins are delivered by cesarean section at 34 weeks. However, many monoamniotic twins experience life-threatening complications as early as 26 weeks, and need to be delivered immediately. Preterm delivery is often associated with a number of life-threatening conditions. BUT Dont get scared by all this vital information this group is for expectant and parents of MoMo twins to show you and others that MoMo twins isnt as all bad as it seems.
