VBAC Chances? What do you think?

post #1 of 14
Thread Starter 
Okay, ladies. I finally got my hospital records from DS's birth 19 mos ago. It was an interesting experience reading through them and seeing the clinical perspective of what happened. My purpose in posting here is to see whether any of you have heard of my physical anomaly (a steep, 90 degree bend in my sacral promonotory, according to the OB's c/s report) and what you think my chances for a VBAC are, as the OB and CNM just said they think there is 0 chance if I couldn't birth DS who was just under 5 lbs.

Ok, so here are notable notes from my birth story and records; sorry for the novel--it was a pretty long labor:

Me: healthy, normal weight, primip, 29 years
Prep: Seeing a CNM and planning an unmedicated/natural birth at the only baby friendly hospital in my state. Did Hypnobabies Homestudy religiously from 30 weeks on. I also had a doula (and soula when the labor got into the 2nd day).
Complications: Diagnosed with IUGR at 36 weeks. Induction scheduled at 38w4d after my fundal height actually started getting lower.
Labor: The day before induction "night," I woke around 4 a.m. on Wed. with contrax. They continued all day--assumed they were BH until SROM around 4 p.m. Went to hospital b/c of the IUGR--baby needed to be monitored occasionally. They couldn't get my contrax to register with the external monitor and didn't believe I was in labor. Finally submitted to an internal monitor as they gave me the "choice" between that and pit. Discovered I was in fact having quite strong contractions though they were fairly irregular.

Because I wasn't dilating quickly, they started pit that first night in the hospital (at a 1), but discontinued it when I began hyperstimming and the baby began having some concerning hearttones b/c of that. They started amnio-infusion, which seemed to fix both problems.
The CNM's notes also note "gestational hypertension" at midnight the first night, although I did not have any signs of Pre-E as far as protein in urine, etc. At that point, I was 4 cm, 80% effaced, and -2.

Labored for another 20 hours or so on my own, mostly in bed, left-sidelying as baby's heartreat did not recover well and he had a continually (but gradually) lowering baseline throughout my labor. At some point during the day, the baby's hearttones got very concerning, and they discontinued the amnio-infusion, which made baby happier. After it was turned off, I did get out of bed and sat on the birth ball, squatting.

At 3:45 p.m., I was 5-6/95% effaced/+1 station.

Soon thereafter, I squatted in the shower for 2 hours, which was really good. Soon after that I experienced what I think was transition--everything suddenly felt different to me, and I got very tearful and people who were in the room thought I was in pain, although I just felt everything more intensely and suddenly got scared. I also felt the urge to push and felt my body push maybe a couple of times. The CNM checked and said I was a stretchy 7.5/95% effaced/0 station and that when I felt like pushing between contrax to call her, and she thought it would be soon.

A couple more hours go by, and I stopped feeling the urge to push. The CNM reports I was a 5-6/90% effaced/0 station. At that point, since I was "un-dialating," the MW recommended an epidural to see if it was a matter of relaxation--I asked if we could try the pit again instead, and she said no b/c it wasn't a matter of contrax not being there and they didn't want to start the hyperstimming again. Got the epidural. No change--restarted pit, and the heart-rate monitor then went off steadily for the next hour (so annoying). They also had me wearing an oxygen mask starting sometime shortly before the epidural. They flipped me around trying to find a position to make baby happy, but couldn't seem to find one.

The OB & CNM finally came and in said it was "time" to go for a c/s (this is about 44 hrs after contrax started and 36 after ROM). The MW said she felt that something was wrong that was keeping things from happening--she mentioned maybe a short cord. It's funny b/c my records state they discussed "expectant management v. c/s" with me and I chose the c/s, but they definitely presented as the only option at that point.

Ok, so the C/s report says my pre-op and post-op diagnosis was "arrest of dialation" and "fetal intolerance to labor." OB says that baby was "occiput posterior presentation" (which I know could definitely make a difference in how difficult/slowly labor might progress) though the CNM report says that he was LOA (and that is always what we saw during labor--I had 2 u/s). The OB notes that my uterus was exteriorized and noted to be "somewhat arcuate" but without a septum. She also says, "of note, prior to completing the procedure, the sacral promontory was palpated and it was noted to have a sharp 90 degree bend, which likely contributed to the arrested labor." The CNM and OB also reported that I had the tightest abs they had ever worked on.

After the surgery, the OB said that she did the c/s in such a way as to make me a good VBAC candidate (we had talked about it before the c/s) but that she did not think I would be able to birth vaginally with the sacral anomaly. The CNM has rehearsed the same with me in several follow-up appointments. She said that taking into account DS's tiny size (he was 4 lb 15 oz), my overly tight abs, and the sacral bend thing, she definitely did not think I'd be able to birth a normal-sized baby if I couldn't birth him.

I just continue to wonder whether the IUGR might have caused my body to not respond correctly somehow. The CNM also specifically said that my issue (the sacral promontory) wasn't one of those bones that could be moved with ligaments loosening when I asked about that.

Overall, I was interested to see that my official diagnosis was "failure to descend" when from mine and DH's recollection, they told us we needed to do this for the baby's safety (I know, it's the same line most c/s moms get; it still just surprises me having been there and heard those alarms going off non-stop for the last 2 hours of labor!).

If anyone is still reading, thank you and i'd love to hear your thoughts. I plan to get an appt with a homebirth midwife (no dog in the fight) for some help in deciphering the parts of my records I can't read/understand (the handwriting--OMG!) and getting another perspective. Just hoping to hear from some who might have BTDT in the meantime...

ETA: DS also had "significant molding" of his head (of course) and a gouge on the side of his scalp toward the front, but on the side. I've always wondered where that came from--the CNM just said "birth trauma." I can still see the scar from it today.

I really couldn't say how an unusual sacral promonatory will affect labor and birth, I just don't know, but here's my perspective. If you want to try for a vaginal birth and you have another arrest of labor or fetal distress, you can always go for a C/S and know you tried. You'll also know that your baby's ready to be born and got the hormones of labor. But it's also totally understandable if you'd want to schedule a C/S after such a long and difficult labor.

I hope everything goes well for you either way.

Yes, I definitely do not plan to schedule a c/s at this point. I guess it's more a question of whether to get my hopes up for being able to successfully birth a baby, if you know what I mean. Also, DH is totally freaked by the idea of my laboring that long again.

Nobody else ever heard of problems with the sacral promonotory? Maybe I should post on ICAN?

post #5 of 14

I have honestly never heard of this, even with all of the research and learning about uc that I've done (which learning covered a lot of potential problems, some of which I'd not heard of even though I'd had three births).

 

I, myself, would labor as long as I could. You may very well have a vbac. I wish I knew enough to give you perspective.

Thanks for the reply. I did cross-post on ICAN, and got several responses of there, with the suggestion to see a chrio with my records to get an unbiased opinion and also possibly an x-ray (even though it would be the non-pregnant version). Still no one else seems to have heard of the sacral promonotory issue particularly, though...

An internet search for the "sacral promonotory"? If so, yes. When I search for the term, I get links to some threads (some from ICAN and MDC) but they don't offer much in the way of explanation and none of them are about the "90 degree bend," so unfortunately, the Dr. Google hasn't prooved too helpful in this case. I don't know if there's some other terminology I should be looking for....

 

And yes, I was flat on my back during the C/S, so that's the position in which the OB was feeling of it. Something perhaps I should clarify is that this finding was based entirely on what the OB felt when she had exteriorized my uterus and then went feeling around to see if there was anything weird that she could not visualize. She and the CNM both put their hands into my body cavity and into the pelvis to feel "the bend."

Okay, I've got some information that just might be helpful, op. As I was reading it just now, I thought of you. Below is an excerpt. Anyway, I'm sending you the links. I really, really hope this helps.

Katy showed me in a mirror just how far my sacrum was pulled into my body. That explained why I kept ending up in the same predicament after each baby

KB: I like to think of the PF (pelvic floor) like a trampoline--the material is supple, but taut...the perfect muscle length.

KB: A kegel attempts to strengthen the PF, but it really only continues to pull the sacrum inward promoting even more weakness, and more PF gripping. The muscles that balance out the anterior pull on the sacrum are the glutes.

Hi A Random Phrase! Thanks so much for thinking of me! I took a look at the blogs you linked me to, and it doesn't sound like it relates to my issue, but I definitely plan to check some of the poses to see what my tailbone, etc. is doing next time I get access to a full-length mirror. I already do a lot of squatting and did even more when I was pregnant, as it's one of the exercises that Hypnobabies really recommends.

 

However, I did find out something this week--I contacted a CNM who blogs, and asked her if she'd ever heard of the sacral promonotory issue before, and she HAD! She actually had a client with exactly the same thing. Her first delivery ended in C/S and that was when the midwife felt the promonotory. She said it feels like a shelf, and that she couldn't see how the woman would be able to birth vaginally, but she DID in her next pregnancy! I am so excited to hear that someone else was successful after hearing this issue--it gives me great hope!

 

Anyway, thanks again for posting the links and trying to help me figure out my problem!

The Pink Kit might be helpful for learning how to create space and understanding how to work with your anatomy. http://www.birthingbetter.com

 

There was a lot going on with your first birth. One thing to keep in mind is that labor, especially first labors and VBAC labors can have long warm up phases and also pauses that don't mean anything is wrong, just that your body is warming up, baby is repositioning or body is taking a break. If you are in the hospital, that is not allowed to happen. If you are out, you can rest during the breaks. Hopefully next time you will not have IUGR and will be able to stay out of the hospital longer or even better, have a homebirth!

Are you currently pregnant? If no then I would suggest a consultation and possibly massage work with a Mayan Pracitioner or if one is not close to you maybe consult a sacral-cranio therapist.

konayossie, it sounds like you're making headway and it sounds like you have a chance at a vbac. Best of luck. I've had a c-section and 2 vbacs, but the c/s was for a different reason.
