Terry jworrall@alaska.net wrote: At 13 weeks a transvaginal scan will often (but not always) permit a very good view of the fetal head. I am not sure what "mild" ventriculomegaly is, but probably the atrium of the lateral cerebral ventricle measures between 10 and 15 mm. If a good view of the fetal head can be obtained, you would be able to evaluate the posterior cerebral fossa, and look at the posterior end of the occipital horn (is it rounded or pointed?) the cisterna magna, and the cerebellum. Remember that this early in pregnancy the cerebellar vermis is not completely formed, so as you scan the posterior cerebral fossa inferiorly, you may mistakenly think you have a Dandy Walker situation. I am not sure you would see the cavum septi pellucidi that early. Hopefully, in addition to the nuchal translucency, the patient has been able to obtain the blood test part of that genetic screen, the PAPP-A and beta hcg, so that you will get a proper evaluation of her risk of having a baby with Trisomy 21. I do NOT think mild ventriculomegaly and a nuchal translucency of 2.6 mm would be an indication for amniocentesis or chorionic villus sampling but I guess that depends on where you practice and what the custom is in your location. As always, I hope Anita and Prathima will comment.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
