Hello,
I am 24 1/2 weeks pregnant. All first and second trimester screenings have been normal. At my 20 week ultrasound, my OB was concerned because the baby's left lateral ventricle was at the top end of the normal range (measuring 10 mm). I went for a level 2 ultrasound and the left ventricle was measuring between 8 and 9 mm. Just to be safe, the high-risk asked me to return in 3 weeks for one more level 2 ultrasound, which was today. We had a different ultrasound tech today, who did not seem as thorough as our previous tech. She only measured the baby's left and right ventricles one time (the previous tech measured each one numerous times just to determine accurate measurements). She measured the left ventricle at 7 mm today. Is it normal for the measurements to actually go down (from 8-9 mm to 7 mm)? It seemed that the right ventricle (even though it was not of concern) also decreased in size from 5-6 mm to 4 mm. If you would please let me know if a decrease in the size of ventricles is normal, and if you think there is anything else I should be asking, I would greatly appreciate it. Thanks!
