While c-sections have become a norm for many mothers, several of them still prefer to undergo a normal delivery. In many cases, after a c-section for their first delivery they may opt for a natural birthing for the subsequent ones – this is known as vaginal birth after c-section or VBAC. At Ankura Hospital, provided there are no additional risk factors to the mother or the baby, we encourage mothers-to-be to explore and undergo VBAC, should they so desire to.
The key to a successful VBAC is a continuous conversation with your gynaecologist and regular electronic foetal monitoring. Having an open mind is essential and allowing the gynaecologist to take the most informed decision is critical.
Not all women are candidates for VBAC and likewise not all challenging cases can be out rightly ruled out. The reasons for a previous C-section play a vital role in determining the current possibility of vaginal birth.
Age is a critical factor, the relation between VBAC and age being that – the older you are the less likely you are to be able to deliver by conventional methods following a C-section delivery. Obesity or higher body mass index is also a limiting factor as is the higher birth weight of the to-be delivered baby.
The first pointer would be if the previous C-section was a low-transverse uterine incision. If this criterion is met, then there is a good chance a second pregnancy can be culminated in a natural birth. Also, important is that one shouldn’t have had any other or major uterine surgery or suffered a uterine rupture.
Critical to the possibility of a VBAC is also the pregnancy term, if you have had a longer (over 40-week) pregnancy you are much less likely to have a vaginal birth; and similarly if you have had less than 18 month gap between the two pregnancies even that could be an impending factor.
A vaginal birth or VBAC helps you avoid an abdominal incision/surgery and mitigates the risks that are consequent to such surgery. Risks such as excessive bleeding, complications associated with a C-section, possible infections are all avoid if a vaginal birth is possible.
Some of the possible risks associated with VBAC include - a uterus rupture that can lead to severe blood loss for the mother and oxygen deprivation for the child. There is also a real risk of serious complications for the child leading to long-term neurological damage or even fatality. All these risks are further escalated if there has been a case of an unsuccessful VBAC in the past.
