Detailed Answer:
Hello,

Thanks for posting your query.

The crown-rump length of the fetus is corresponding to about 12 weeks gestation. The nuchal translucency is within normal limits. The fetal heart rate also is well within the normal range.

The diagnosis of circumvallate placenta through sonogram is not always accurate. A repeat sonogram, associated medical history like previous illnesses, history of curettage in the past etc., may help in arriving at a conclusion.

Management requires good monitoring facilities during labor and once pregnancy enters term.

Hope I have clarified your query. Please feel free to contact for further information. I will be happy to help.

regards,
Shanti.V.
