A transverse prevarication position in pregnancy means that the baby is horizontal in your belly. The position of the baby becomes an issue as your due date approaches. The optimal position for vaginal delivery is the head down or vertex position. Approximately 2% to thirteen% of babies are in malposition in the third trimester, some of which will turn to the vertex position before delivery.

Transverse lie position is uncommon, even amidst non-vertex presentations. In fact, by 37 to 40 weeks gestation, only 2% of babies are in malposition, with approximately only 20% of those in the transverse lie position.

What Is a Transverse Baby Position?

Baby position is the way the infant faces in the uterus—if the infant is facing your lesser, they are anterior, and if they face your belly, information technology's called posterior. (This is based on the position of the back of your baby'southward head.) The transverse lie position is where the baby'due south head is on ane side of the mother's body and the anxiety on the other, rather than having the head closer to the cervix or the heart. The baby can likewise be slightly at an angle, but still more than sideways than up or downwardly.

Before birth, your baby is in many dissimilar positions in the uterus. When talking about where the infant's caput is, doctors apply the terms cephalic (head down) and vertex (crown of the head down), which as noted to a higher place, ways the head is towards your feet, and breech, which means the head is upwardly towards your center.

The sideways position in the uterus is more common before in pregnancy when the babe has space to move around freely. Equally noted above, 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 baby by placing their hands on your belly in a series of movements known as Leopold'southward Maneuvers. They may also request an ultrasound exam be done to confirm the position of your baby.

Typically the position of the baby is non a concern until the terminal trimester of pregnancy. At this point, the medico or midwife may check your baby's position at every visit. As noted above, the vast majority of babies will be head down at nascency.

Why Babies May Exist in a Transverse Lie

Sometimes, it is unknown why a babe is in a malposition, other times in that location are contributing factors, such as in the case of an atypically-shaped uterus or pelvis. Some of the more common reasons why a babe may be in the transverse lie position include the post-obit:

• Aberration of the uterus
• Having a cyst or fibroid blocking your cervix
• Pelvic construction
• Polyhydramnios (too much amniotic fluid) or low fluid levels
• Position of the placenta
• 2nd (or more) pregnancy
• Twin or multiple pregnancy

The biggest factor in whether or non your babe is in a transverse prevarication position (and if they will turn to another position on their own) is why the baby is transverse in the commencement identify. For example, having a bicornuate uterus, where the uterus has two sides, can hateful that your babe fits meliorate inside when in the transverse position. Sometimes, it is due to an issue like low amniotic fluid not giving your baby the room to plow head down or vertex.

Potential Complications With a Transverse Baby

A baby who is transverse will not fit in the pelvis, making a safe vaginal birth very difficult, if non impossible. A baby in the transverse position merely doesn't fit through the vaginal canal. Additionally, at that place is added run a risk of cord prolapse and other complications.

Ofttimes, the baby will move themselves into the right position or they can exist manually repositioned. A cesarean department may exist needed if the baby cannot be turned.

Turning a Transverse Baby

There are things yous can do to assistance your baby rotate into a more favorable position if they don't do then on their own. Your doctor or midwife may suggest exercises or positions you can exercise to promote repositioning. If your baby stays transverse, your doctor may practice an external cephalic version (ECV), this is where they try to plow the infant from the outside using pressure on the baby's head and buttocks. This procedure tin be painful for the female parent, but pain relief may be used and complications are rare.

However, some babies are easier to turn than others. Plus, the procedure can non exist done in certain circumstances, such as with twin or multiple pregnancies. That said, this procedure is often successful, particularly if the doctor is experienced in the technique. Typically, it is performed anywhere from around 36 weeks until commitment every bit long every bit the water has not broken and other atmospheric condition are favorable. Nonetheless, it'due south easier to turn a smaller baby than a full or mail-term 1.

I 2013 study, whose authors advocate for practitioners to learn and use repositioning methods more oftentimes, reported a 100% success rate in turning babies in the transverse lie position. However, generally, success rates for ECV are effectually 65%, with even higher positive outcomes for women who've given birth before.

When the Baby Doesn't Turn

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

Know that even if interventions to go the baby to turn work, some babies will revert back to the transverse prevarication or breech positions.

A Word From Verywell

Remember, the end goal is a prophylactic commitment, and ultimately, all that matters is catastrophe upward with a healthy baby in your arms.
