Cesarean scar

Women who delivered their first baby by cesarean section may be wondering what their options are for delivering their second child. For a long time, women who had a Cesarean delivery were advised that a C-section for all future pregnancies is their only option. For women who are hesitant to go through surgery or want to try a vaginal delivery because they want to avoid anything from more cesarean scars to complications from surgery, it’s important to consider the pros and cons of another C-section delivery.

Doctors have long advised repeat C-sections versus vaginal birth after Cesarean (VBAC) because they fear rupture of the uterus during labor1. This complication happens when the Cesarean scar on the uterus breaks open and doctors have to perform an emergency C-section. They may also have to remove the uterus to save the mother’s life.

Cesarean Scar: The Different Types

The type of Cesarean scar can also affect the ability of a woman to choose a VBAC. These are the scars that result from a C-section2:

  • Classic high vertical - The cut is a long line from the navel to the pubic area. This used to be the standard cut, but as it is a large cut, it’s risky and only performed for emergency deliveries. The cesarean scar is also bigger and therefore more noticeable.
  • Classic low vertical - This up-and-down cut is performed on the lower part of the uterus. Only around 4 inches long, the cesarean scar may be covered with underwear.
  • Transverse or bikini cut - This is a low, side-to-side line on the lower part of the abdomen. The resulting cesarean scar is less noticeable and therefore makes this the most preferred cut.

While a uterine rupture is a risk, it is rare, occurring in less than 1% of women who go through a trial of labour, or a planned attempt to give birth vaginally. This is why more and more mothers elect to do VBAC.

Benefits of a Repeat C-Section

Recent studies support that a repeat C-section is still safer for both mother and baby, however.

The Australian Research Centre for Health of Women and Babies in Adelaide, Australia, found that 2.4% of babies born by a planned vaginal birth after a previous C-section birth died or had serious complications, while only 0.9% died or had serious complications among babies born by a planned repeat C-section. Only 0.8% of mothers who elected for a second C-section had severe bleeding compared with 2.3% of those who pursued VBAC3.

The National Institutes of Health (NIH) also conducted its own study about uterine ruptures in VBAC3. The scientists found that there was indeed a low risk of uterine rupture in a second C-section.

The NIH study also revealed that 98% of the mothers who chose a repeat C-section succeeded in that delivery but only 43% of women who planned VBAC were able to deliver successfully. The study further noted that no baby died in the group who chose a planned C-section, but that two babies were stillborn among the 1,225 planned VBAC deliveries.

The risks for mother and baby are small but still significant. For this reason, a trial of labour is now considered to be safe for the mother to attempt, but a repeat C-section may present lower risks for both her and her child.

Risks of a Repeat C-Section

Giving birth is not risk-free, whether it is through vaginal or cesarean delivery. Doctors agree that the safest delivery method is still an uncomplicated vaginal birth and that is why they always recommend it for first-time mothers. However, there is no guarantee a delivery will be uncomplicated, which is why C-sections happen.

A C-section is surgery, which means it comes with risks. A repeat C-section carries an increased set of complications too.

These are the risks that come with repeat C-sections:

  • Longer Cesarean section recovery period. Since the abdomen was opened up, the body will need a longer time to heal. A healing wound can also make caring for a newborn more difficult for a new mother.

  • Infection of the wound. The mother and her doctor must be alert for any signs of infection in the area such as pus, pain, swelling, and inflammation.

  • Injuries to the bowel and bladder. Adhesions, or scar-like tissue, develop during each C-section. When the adhesions that form are thick or dense, it can make a repeat C-section more difficult to perform. This increases the risk of injuries to the bladder or the bowel.

  • Placenta accreta3. Multiple C-sections increase the risk of developing placenta accreta, which is when the placenta implants deeply into the uterine wall or near the cesarean scar. This condition increases the risk of heavy bleeding. A blood transfusion may be needed and perhaps a hysterectomy.

  • Uterine rupture. While studies have shown that this is a small risk with VBAC, each repeat C-section carries with it an increased risk of cesarean scar tissue buildup.

How you deliver your next baby after a previous C-section is not a simple decision. Talk to your obstetrician about the risks and benefits of a repeat C-section so you can make the best informed choice for you and your baby.
