Vaginal Birth After Cesarean (VBAC) refers to delivering a baby vaginally after having a previous C-section for a prior pregnancy. Many women wish to attempt VBAC delivery due to its numerous potential benefits, including a shorter recovery time, fewer surgical complications, and the ability to avoid the risks associated with repeat cesarean sections. However, VBAC delivery comes with specific risks and benefits that must be carefully weighed.
VBAC typically allows for a faster recovery than a repeat C-section. Women who deliver vaginally after a previous C-section generally experience less postoperative pain and can return to their daily activities more quickly.
VBAC can help avoid the risks associated with repeat cesarean deliveries, such as infection, heavy blood loss, and organ injury. Vaginal births usually result in fewer complications compared to surgical births.
Women who have multiple C-sections may face increased risks of complications in future pregnancies, such as placenta accreta or uterine rupture. Choosing VBAC may help lower these risks in subsequent pregnancies.
The most significant risk of VBAC delivery is uterine rupture, where the scar from the previous C-section opens during labour. This can be dangerous for both mother and baby and may require immediate surgery.
In some cases, the baby may show signs of distress during a VBAC delivery, requiring urgent medical intervention, such as a C-section.
VBAC in pregnancy can result in longer labour, particularly if the cervix does not dilate properly or if there are complications with the baby's position.
Recognising early warning signs of pregnancy is essential for the health of both the mother and baby. By addressing these signs promptly, you reduce the risk of complications such as miscarriage, preterm labour, and preeclampsia. Here’s why it’s important:Not all women who have had a C-section are eligible for a vaginal birth after C-section (VBAC). Several factors influence whether VBAC is a safe option:
If the previous C-section was performed with a low-transverse incision, which is the most common type of incision, the chances of successful VBAC delivery are higher. A vertical incision on the uterus may increase the risk of uterine rupture, making VBAC less safe.
The reason for the previous C-section plays a crucial role in determining eligibility. If the previous C-section was performed due to non-recurrent issues (e.g., breech presentation, fetal distress), you may be a good candidate for VBAC. However, if the C-section was due to issues like cephalopelvic disproportion (when the baby is too large), a repeat cesarean may be advised.
Women with pregnancy complications such as gestational diabetes, hypertension, or multiple gestations (twins) may not be good candidates for VBAC due to the increased risks.
