Subchorionic Hematoma & Chromosomal/NT Defect Risks: What You Need to Know

Question
My doctor doesn't sugar coat things.  When I asked if things were looking better because my subchorionic hematoma had significantly decreased in size, she made me feel really uneasy.  She explained that I am still high risk and the question is whether or not there is something wrong with the baby that may have caused the SCH.  Are SCH's associated with chromosomal or NT defects?  Thank you so much for your help.

Answer
Subcnorionic hematomas develop due to a sequestration of blood within the folds of the developing placenta. They do not have ANYTHING to do with the fetus and do not lead to miscarriage or problems with the pregnancy or the fetus. Usually, they dissipate within a few weeks and can be followed by serial sonography. They have nothing to do with chromosomal or neural tube defects. The presence of a SCH does not cause you to be high risk.
