Breech presentation at birth occurs when a baby's feet or buttocks are positioned to be born first, rather than the head. This can be a concerning situation for expectant mothers, as it may pose risks for both the mother and the baby during delivery. As an obstetrician with over a decade of experience in managing high-risk pregnancies, I aim to provide a comprehensive overview of breech presentation, including its causes, risks, and management options.
The American College of Obstetricians and Gynecologists (ACOG) estimates that approximately 3-4% of pregnancies at term are complicated by breech presentation. While this may seem like a relatively rare occurrence, understanding the factors that contribute to breech presentation and the available management options can help alleviate concerns and promote a positive outcome for both mother and baby.
Causes of Breech Presentation
Several factors can contribute to breech presentation, including:
- Premature birth: Babies born prematurely are more likely to be in a breech position due to their smaller size and increased mobility.
- Multiple pregnancy: Twins or other multiples are more likely to be in a breech position due to the crowded uterus.
- Uterine anomalies: Abnormalities in the shape or structure of the uterus can increase the risk of breech presentation.
- Placental location: A placenta located in the lower part of the uterus (placenta previa) can cause the baby to move into a breech position.
- Previous breech pregnancy: Women who have had a previous breech pregnancy are at increased risk of having another breech presentation.
Types of Breech Presentation
There are several types of breech presentation, including:
| Type of Breech | Description |
|---|---|
| Frank Breech | The baby's buttocks are positioned to be born first, with their legs folded up towards their chest. |
| Footling Breech | The baby's feet are positioned to be born first, with their buttocks and legs extended. |
| Complete Breech | The baby is sitting cross-legged in the uterus, with their buttocks and feet positioned to be born first. |
Risks Associated with Breech PresentationBreech presentation can pose several risks for both the mother and the baby during delivery. These risks include:
- Umbilical cord prolapse: The umbilical cord can become compressed or prolapsed, cutting off oxygen to the baby.
- Birth asphyxia: The baby may experience oxygen deprivation during delivery, which can lead to brain damage or other complications.
- Shoulder dystocia: The baby's shoulder can become stuck during delivery, which can lead to birth injuries or complications.
- Increased risk of cesarean section: Breech presentation often requires a cesarean section, which can increase the risk of complications for the mother.
Management Options for Breech Presentation
Management options for breech presentation depend on several factors, including the type of breech, the gestational age, and the mother's overall health. These options include:
- External cephalic version (ECV): A procedure in which the healthcare provider attempts to manually turn the baby into a head-down position.
- Cephalic version by ultrasound guidance: A procedure in which the healthcare provider uses ultrasound guidance to attempt to turn the baby into a head-down position.
- Vaginal breech delivery: A vaginal delivery in which the baby is born feet or buttocks first.
- Cesarean section: A surgical delivery in which the baby is born through an incision in the abdomen.
