A transverse lie position in pregnancy means that the baby is horizontal in your belly. The position of the baby becomes an issue as your due appointment approaches. The optimal position for vaginal delivery is the head down or vertex position. Approximately ii% to 13% of babies are in malposition in the third trimester, some of which will plough to the vertex position before delivery.

Transverse lie position is uncommon, even among non-vertex presentations. In fact, by 37 to 40 weeks gestation, only ii% of babies are in malposition, with approximately only 20% of those in the transverse lie position.

What Is a Transverse Baby Position?

Babe position is the way the infant faces in the uterus—if the baby is facing your bottom, they are anterior, and if they face your abdomen, it'south called posterior. (This is based on the position of the back of your babe's head.) The transverse lie position is where the babe's head is on ane side of the mother'south body and the feet on the other, rather than having the head closer to the cervix or the heart. The baby can also be slightly at an angle, but yet more sideways than up or down.

Before birth, your baby is in many different positions in the uterus. When talking almost where the baby'due south caput is, doctors utilize the terms cephalic (head downwards) and vertex (crown of the head down), which as noted above, ways the head is towards your anxiety, and breech, which means the head is upwardly towards your heart.

The sideways position in the uterus is more common earlier in pregnancy when the babe has space to motion around freely. As noted in a higher place, very few babies remain in this position at term.

Checking Baby's Position

Your doctor or midwife will typically be able to tell the position of your babe by placing their hands on your belly in a serial of movements known equally Leopold'south Maneuvers. They may besides asking an ultrasound exam be washed to confirm the position of your baby.

Typically the position of the baby is non a concern until the last trimester of pregnancy. At this point, the doctor or midwife may bank check your baby's position at every visit. Every bit noted above, the vast bulk of babies will be head down at nascency.

Why Babies May Exist in a Transverse Lie

Sometimes, it is unknown why a baby is in a malposition, other times at that place are contributing factors, such as in the example of an atypically-shaped uterus or pelvis. Some of the more common reasons why a baby may exist in the transverse lie position include the following:

• Abnormality of the uterus
• Having a cyst or coarse blocking your cervix
• Pelvic structure
• Polyhydramnios (too much amniotic fluid) or depression fluid levels
• Position of the placenta
• 2nd (or more) pregnancy
• Twin or multiple pregnancy

The biggest factor in whether or not your baby is in a transverse lie position (and if they will turn to another position on their own) is why the baby is transverse in the get-go place. For example, having a bicornuate uterus, where the uterus has two sides, can mean that your baby fits ameliorate inside when in the transverse position. Sometimes, it is due to an result like low amniotic fluid not giving your baby the room to turn caput downwardly or vertex.

Potential Complications With a Transverse Baby

A infant who is transverse will not fit in the pelvis, making a safe vaginal birth very hard, if non impossible. A babe in the transverse position simply doesn't fit through the vaginal culvert. Additionally, there is added risk of cord prolapse and other complications.

Often, the babe will motion themselves into the correct position or they tin be manually repositioned. A cesarean department may be needed if the baby cannot be turned.

Turning a Transverse Baby

At that place are things you can practise to help your infant rotate into a more favorable position if they don't exercise and so on their own. Your doctor or midwife may propose exercises or positions you can exercise to promote repositioning. If your babe stays transverse, your doc may do an external cephalic version (ECV), this is where they attempt to turn the baby from the outside using pressure level on the baby's head and buttocks. This procedure can be painful for the mother, but hurting relief may be used and complications are rare.

However, some babies are easier to turn than others. Plus, the procedure tin not be done in sure circumstances, such as with twin or multiple pregnancies. That said, this procedure is often successful, especially if the doctor is experienced in the technique. Typically, it is performed anywhere from effectually 36 weeks until commitment as long equally the water has not broken and other weather are favorable. All the same, it'due south easier to turn a smaller baby than a total or mail service-term 1.

One 2013 study, whose authors advocate for practitioners to acquire and use repositioning methods more often, reported a 100% success charge per unit in turning babies in the transverse lie position. Notwithstanding, generally, success rates for ECV are effectually 65%, with even higher positive outcomes for women who've given birth before.

When the Infant Doesn't Turn

If your baby is in a transverse prevarication position at term, a cesarean department may be recommended if the baby doesn't plow or if other measures are not successful in turning the baby.

Know that even if interventions to get the baby to turn work, some babies volition revert back to the transverse lie or breech positions.
