Understanding Other Specified Multiple Gestation with Two or More Monochorionic Fetuses

When a woman is pregnant with more than one baby, it is referred to as multiple gestation. This can happen in a number of ways including fraternal or identical twins. However, there are also cases where the fetuses share the same placenta, known as monochorionic twins. When a woman is pregnant with two or more monochorionic fetuses, it is referred to as Other Specified Multiple Gestation with Two or More Monochorionic Fetuses, or OS-MOM.

The diagnosis of OS-MOM is typically made during a routine ultrasound examination. The ultrasound will show two or more fetuses sharing the same placenta. While this can be an exciting time for expectant parents, it is important to understand that pregnancies with two or more monochorionic fetuses can come with increased risks.

1. Higher risk of twin-to-twin transfusion syndrome (TTTS)

TTTS occurs when the blood flow between the fetuses is imbalanced. This can lead to one fetus receiving too much blood, which can cause heart failure, while the other fetus doesn't receive enough blood, which can cause growth problems. Twins who share a placenta are at a higher risk of developing TTTS.

2. Increased risk of preterm labor

Due to the increased demands on the mother's body, pregnancies with two or more fetuses are at a higher risk of preterm labor. This means the babies may be born before they are fully developed, which can lead to a range of complications.

3. Higher risk of fetal growth problems

When two or more fetuses share a placenta, they may not get equal amounts of nutrients. This can lead to one fetus growing at a slower rate than the others, which can cause long-term health problems.

4. Increased risk of preeclampsia

Preeclampsia is a serious pregnancy complication that can lead to high blood pressure and damage to organs. Women who are pregnant with two or more fetuses are at a higher risk of developing preeclampsia.

5. Need for more frequent monitoring

Due to the increased risks associated with pregnancies with two or more monochorionic fetuses, expectant mothers will need more frequent monitoring. This may include more frequent ultrasound examinations, fetal monitoring, and visits with a maternal-fetal medicine specialist.
