Patient's Query

Hi doctor,

I had Doppler MCA. The report showed MCA-PSV value of 0.79 MoM. What does it indicate? Please explain.

Hello,

Welcome to icliniq.com.

Why have you undergone the Doppler of the MCA (middle cerebral artery)? Though you may be an Rh negative woman, is it your first pregnancy? In that case this is not needed. We only advise this if an Rh negative woman has previous history of childbirth or abortion and has not been immunized. However, this reflects whether your fetus is normal or anemic due to the lack of RBC (red blood cells), which gets destroyed due to isoimmunization. The peak systolic velocity (MCA-PSV) cutoff value recognized world wide is 1.29 MoM and the value above it needs clinical testing as well as blood testing. Your value is much below the range and showing the fetus inside you does not have any anemia at present. However, a repeat testing with an interval of four weeks is needed up to 34 weeks.

Thank you doctor,

Is there any serious issue? Can you please tell the solution?

As far as the report you have sent, there is no such serious issue. This is an absolutely healthy pregnancy now.
