Thoughts on VBAC after three or more prior cesareans

Thoughts on VBAC after three or more prior cesareans

Note regarding “TOLAC.”  When reading from medical texts, remember that you are no longer in the land of emotion and warm fuzzies.  Rather, envision that you have been transported to another world, a clinical world, where terms like TOLAC/TOLAMC, or trial of labor after (multiple) cesareans, are used.  I don’t think that most care providers understand the emotional sting that many women seeking VBAC associate with the term TOLAC.  It’s important for women to understand the language care providers use so that they can translate TOLAC into “planning a VBAC” and not feel slighted.  You might want to read this article which describes what the term TOLAC means, how it’s used in medical research, and why it’s not synonymous with VBAC.

________________________________

A mom recently asked, “Does anyone have some facts on VBA3C?”

I provided this collection of info…

Who makes a good VBAC/VBAMC candidate?

ACOG’s 2010 VBAC recommendations affirm that VBA2C (vaginal birth after two cesareans) is reasonable in “some” women.  But they remain silent on VBAMC (VBAC after multiple cesareans.)

Some have interpreted that silence to mean that ACOG does not recommend VBAMC, yet ACOG is clear that women shouldn’t be forced to have cesareans.

Between what they say about VBA2C and who is a good VBAC candidate, we might be able to discern who might be a good VBAMC candidate.

A couple things to keep in mind while reading…

Reason for prior cesarean/history of vaginal birth.  Research has shown that women who have had cesareans for malpresentation (breech, transverse lie, etc) and/or a history of a prior vaginal delivery would have the highest VBAMC success rates.

Scar type.  Low transverse incisions (also called bikini cuts) carry the lowest risk of rupture in comparison to classical, high vertical and T/J incisions.  With the likely increased risk of uterine rupture in a VBAMC, having low transverse scars is a way to minimize that risk as much as possible.

What does ACOG say about VBAC?

In ACOG’s 2010 VBAC guidelines, it describes the qualities of a good VBAC candidate:

The preponderance of evidence suggests that most women with one previous cesarean delivery with a low transverse incision are candidates for and should be counseled about VBAC and offered TOLAC.  Conversely, those at high risk for complications (eg, those with previous classical or T-incision, prior uterine rupture, or extensive transfundal uterine surgery) and those in whom vaginal delivery is otherwise contraindicated are not generally candidates for planned TOLAC.  Individual circumstances must be considered in all cases, and if, for example, a patient who may not otherwise be a candidate for TOLAC presents in advanced labor, the patient and her health care providers may judge it best to proceed with TOLAC.

What does ACOG say about VBA2C?

In those same guidelines, ACOG specifically addresses VBA2C:

Given the overall data, it is reasonable to consider women with two previous low transverse cesarean deliveries to be candidates for TOLAC, and to counsel them based on the combination of other factors that affect their probability of achieving a successful VBAC.  Data regarding the risk for women undergoing TOLAC with more than two previous cesarean deliveries are limited (69).

The power of context and training

How a provider approaches VBAMC depends a lot on their training as well as the support of their hospital administration. In the video below, Dr. Craig Klose discusses the merits of vaginal birth after cesarean and the various factors that may impede women obtaining VBAC.

One thing that stood out to me was Dr. Klose’s comments on VBAC after multiple prior low transverse cesareans (LTC). To sum, he says that he was taught that multiple LTCs were “no biggie” and he has attended up to VBA5C. This is the power of training and context!

ACOG guidelines, your legal rights, and “forced” cesareans

As attorney Lisa Pratt asserts, “ACOG guidelines are just that, guidelines, they are not law; while it is nice when they put out a guideline that supports your factual situation, falling outside of their recommendation does not mean you must consent to something you do not want.”  You can read more in the article, “VBAC bans, exercising your rights, and when to contact an attorney.”

Further, ACOG’s 2010 VBAC guidelines also say that women cannot be forced to have cesareans even if there is a VBAC ban in place:

Respect for patient autonomy also argues that even if a center does not offer TOLAC, such a policy cannot be used to force women to have cesarean delivery or to deny care to women in labor who decline to have a repeat cesarean delivery.

You may also wish to review your options when encountering a VBAC ban and the story of a mom seeking VBA2C who was threatened with a “forced” cesarean when her OB group withdrew support at 38 weeks.

Making a plan and moving forward

Your best bet is to review your medical records with several VBAC supportive care providers and get their opinion.  Obtain a copy of your medical records and operative reports from each prior cesarean, get the names of VBAC supportive providers, and ask the right questions.

Placenta problems in VBAMC/after multiple repeat cesareans

Placenta problems in VBAMC/after multiple repeat cesareans

I thought that I would take the data from the Silver (2006) that I’ve previously discussed and share it in a different way that would be helpful to women with multiple prior cesareans.  (You might find it worthwhile to read this article specifically, where you can view the data below in graphs, as well as other articles on placental abnormalities first.)  Remember that accreta is when the placenta abnormality deeply attaches into the uterus requiring surgical removal.  There is a 7% maternal mortality rate with accreta as well as a high rate of hemorrhage and hysterectomy.   One of the factors that determines your risk of accreta or previa is your number of prior cesareans.

Whether a mom has a repeat cesarean or a VBA1C, her risk of accreta (including increta and percreta) and previa in that pregnancy are:

risk of accreta: 0.31% (1 in 323)
risk of previa: 1.3% (1 in 77)
risk of accreta if previa is present: 11% (1 in 9)

Whether a mom plans a third cesarean or a VBA2C, her risk of accreta and previa in that pregnancy are:<

risk of accreta: 0.57% (1 in 175)
risk of previa: 1.14% (1 in 88)
risk of accreta if previa is present: 40% (1 in 2.5)

If a mom plans a fourth cesarean or a VBA3C, the risk during that pregnancy increases to:

risk of accreta: 2.13% (1 in 47)
risk of previa: 2.27% (1 in 44)
risk of accreta if previa is present: 61% (1 in 1.6)

The jump in risk from two prior cesareans to three prior cesareans is pretty huge…

If mom plans a fifth cesarean or a VBA4C, the risk during that pregnancy increases to:

risk of accreta: 2.33% (1 in 43)
risk of previa: 2.3% (1 in 43)
risk of accreta if previa is present: 67% (1 in 1.5)

If mom plans a sixth cesarean or a VBA5c, the risk during that pregnancy increases to:

risk of accreta: 6.74% (1 in 15)
risk of previa: 3.4% (1 in 29)
risk of accreta if previa is present: 67% (1 in 1.5)

Here are some stats to consider:

Silver (2006) found the following rates of accreta (including increta and percreta), during the first, second, third, fourth, fifth, and sixth cesareans: 0.24%, 0.31%, 0.57%, 2.13%, 2.33%, 6.74%.  (View a graph of this data.)

In other words, your risk of placenta accreta increases from first to sixth cesarean delivery:
1 in 417,
1 in 323,
1 in 175,
1 in 47,
1 in 43,
1 in 15.

Read more about accreta.

The studies that have been conducted (that I’m aware of) on uterine rupture in VBAMC are kind of small (including hundreds, not thousands of women).  So I don’t think we have an accurate idea of VBA3C rupture risk.  This site is a great resource.

Update:  When I posted a link to this article on Facebook, a mom left this comment:

Thank you for posting. My friend had 2 previous c-sections, and with her 3rd pregnancy had the bad luck of having both placenta accreta and placenta previa (both risks of repeat c-section). Her pregnancy was awful..lots of bleeding, hospitalizations, steriods and other drugs to help hold onto the pregnancy and bedrest at 20 weeks. They couldn’t do cerclage because of the placenta previa). In the end she had a healthy baby, but a 5 hour c-section surgery where she lost a lot of blood and needed a blood transfusion of 6 units of blood. She had to have a hysterectomy and also they removed part of her bladder because her placenta had embedded so far it was attached to her bladder! She was pissed that her doctor never warned her of the risks of repeat c-sections. She is 39 years old.

[and]

yes, you can share my comment. again, my friend ultimately is ok bec she was planning on having her tubes tied after this 3rd unplanned pregnancy — but she was upset initially bec her OB never shared with her any of these risks of repeat c-section…and she said “had I known, I would have really pushed for a vbac with #2”

These are the complication rates that Silver 2006 found in 30,000 women during multiple cesareans.The rates quoted were what he found during the third CS but, I think the accreta and previa rates illustrate the risks that are present during a third pregnancy after two prior CS.In other words, whether a mom has a third CS or a VBA2C, her risk of accreta and previa in that third pregnancy are:

risk of accreta: 0.57% (1 in 175)
risk of previa: 1.14% (1 in 88)
risk of accreta *if* previa is present: 40% (1 in 2.5)

If she has a third CS and becomes pregnant again, the risk during that
fourth pregnancy increases to:

risk of accreta: 2.13% (1 in 47)
risk of previa: 2.27% (1 in 44)
risk of accreta *if* previa is present: 61% (1 in 1.6)

Compare that to the risks in a first pregnancy:

risk of accreta: 0.24% (1 in 417)
risk of previa: 6.4% (1 in 16) [yes, that figure is correct, previa was the reason for many of these women’s primary CS] risk of accreta *if* previa is present: 3% (1 in 33)

That means the risk of accreta increases 887% from the first pregnancy – a huge jump.

So, if it was me, getting that ultrasound and knowing I didn’t have these complications would give me huge peace of mind.
