lateral ventricle 9mm and 2 vessel cord
by tellis6645, Nov 06, 2009 01:26PM
Hello,
We were referred to a perinatologist because my first son was born with a VSD and they wanted to get a good look at the heart. The echo went great, no problems with the heart. However they told me that one of the ventricles in the brain is borderline at 9mm, the others were normal in size. She mentioned that the corpus collusm may be missing and this could lead to the difference in size. She didnt recommend a MRI but rescheduled another ultrasound in 4 weeks to do a followup. In addition the baby also has a 2 vessel cord. Im wondering if these issues can be related. Im also worried because they are both markers for disorders. I cant seem to find any information of the two of them being related together. I was 26weeks 1 day, the baby measured 26 weeks 5 days, the head measured 27 weeks 5 days, and my fundal height was 29cm. There were no other markers found. The quad screen came back negative at 18 weeks.
Thanks!

If the measurement of the lateral ventricle remains less than or equal to 10 mm, there is a good chance for normal neurodevelopment if there are no other abnormalities. If the corpus callosum is truly absent on further scanning, then the risk for long term neurodevelopmental problems is increased (although normal development is still possible).
Generally speaking, the more anomalies found on prenatal ultrasound, the higher the risk of an underlying genetic syndrome. A 2-vessel cord can be found in normal babies, and it might be unrelated to the ventricular enlargement. Further ultrasounds can help determine the significance of both the brain and umbilical cord findings.
