I'm wondering if anyone has specific info regarding placenta praevia. I am 31 weeks pg and my scan last friday showed a low lying placenta, which is 4 cm from the os. I have a meeting with the antenatal care team on friday and would like to know whether there is a chance I can have a trial of labour or whether it is too close. I realise there may be differences of opinion between doctors so any info will help me be better prepared! I have previous exp of vbac in the UK, during my 2nd pg I had a low lying placenta but a late scan showed it had moved sufficiently and I had a wonderful vbac... after an awful CSection previously! I would so love the opportunity to vbac again.
Thanks
Larissa

Hi Larissa,
Have a read of these, the first talks about placental migration and identification of pp on ultrasound, there are a number of similar articles to this.
www.kfshrc.edu.sa/annals/205_206/00-081.PDF
This 2nd one talks about modes of delivery and migration in relation to identifying the best mode of delivery.

Just reading these it sounds like your placenta is low lying but is not previa. The figures in these studies seem to indicate 3cm or closer is previa. Anything further than 3cm seems to be a candidate for vaginal delivery.
The other issue to consider depending on where the placenta is lying is that if the placenta is on the front of your uterus and is low there is also a higher risk of placental accreta as a result of the previous csec. You should investigate the possible consequences of this too in making your decision. Not sure if this can be detected on ultrasound. If the placenta is on the back of your uterus this is unlikely to be an issue.

Thanks so much for that info Debbie, I have 32 week antenatal tomorrow andd your timing couldn't have been better as it gives us something to discuss. I also note that I have another 4 weeks for possible further placental migration... so we can always request a 36 week scan and enquire aabout placenta accreta.
Thanks again x

Just to follow up - last week I gave birth via VBAC at KEMH, Perth. I had a fantastic midwife who followed my birth plan (thanks to birthrites as I borrowed and adjusted from your plan!) and I'm recovering really well.
Thanks Birthrites for helping me to get informed and empowered.
