Ultrasound Shows Amniotic Band

Jane Foley's picture


Dear Ms. Ultrasound,
I am 20weeks pregnant. I had an ultrasound today and found a band (56*4mm) of amniotic membrane across the superolateral part of the gestational sac but not attached with any of fetal parts. All the organs of the baby are fine. I've had a previous D&C.

I've had a previous D&C. I am so afraid of that what will happen next.


It is always scary when a mommy-to-be is told she has an amniotic band. The first thing one usually does is "Goggle" it which can really scare a person . I think with your amniotic band, the good thing is that at 20 weeks there is no fetal involvement. The band is only 5 centimeters which is also good and is high up and to the side in the uterus.

The amniotic band is a result of a ruptured amnion. The amnion is one of the layers of the gestational sac.

Never mind the D&C. This has nothing to do with anything as far as I know. I think the best advice I can give you is to just forget about this finding. Your doctor will keep an eye on you,checking for fetal involvement at different intervals of this pregnancy. Don't read too much on this syndrome because there are extreme circumstances that will cause you unnecessary anxiety. Concentrate on the health of your baby. Everyday visualize your baby staying well away from the band. There really is not a lot you can do with this finding, this is why I am suggesting you try and forget about it and put your energy into the positive.

If after your next ultrasound you have more questions or there are new findings let me know the details and we can discuss them.

With regards
