Monoamniotic-monochorionic Twins: The Rarest Type of Twin
Monoamniotic-monochorionic twins are the rarest type of twin, occurring in only one in every 35,000 pregnancies. This type of twin is formed when a single egg is fertilized and then splits into two embryos. The embryos share the same amniotic sac and placenta, making them monoamniotic-monochorionic twins.
The risk associated with this type of twin is much higher than with other types of twins. The babies can become tangled in their own umbilical cords, which can lead to a decrease in oxygen and nutrients to the babies. This can lead to serious complications and even death.
Because of the increased risk associated with monoamniotic-monochorionic twins, it is important for expectant mothers to receive close monitoring from their healthcare provider throughout the pregnancy. The provider will likely perform more frequent ultrasounds to check for any signs of cord entanglement. If any entanglement is detected, the provider may recommend early delivery to reduce the risk of complications.
In addition to the increased risk, monoamniotic-monochorionic twins also have a higher rate of birth defects than other types of twins. The risk of birth defects is higher because the babies are sharing the same amniotic sac and placenta, which can cause them to be exposed to the same toxins.
Despite the increased risk associated with monoamniotic-monochorionic twins, many women have successful pregnancies and deliveries. With close monitoring and care, the risk of complications can be greatly reduced.
In conclusion, monoamniotic-monochorionic twins are the rarest type of twin and carry a higher risk of complications than other types of twins. It is important for expectant mothers to receive close monitoring from their healthcare provider throughout the pregnancy to reduce the risk of complications. With proper care and monitoring, many women have successful pregnancies and deliveries.
