This fetus shows IUGR or intrauterine growth retardation.
-By biometry fetal age is 29 weeks as opposed to 32 weeks by LMP.
- fetal AC= 26 weeks
In addition color and spectral Doppler studies show:
- high resistance flow in Uterine artery- RI > -0.7 (normally < 0.5)
diastolic notching
- MCA--> low resistance flow with RI< 0.6
-Umbilical A. shows RI > 0.8 (high resistance flow)
- cerebroplacental ratio is reversed with = 0.6/0.8= 0.7 (normally should be > 1)
- fortunately no reverse diastolic flow is seen in umbilical artery or uterine artery
and near normal ductus venosus flow
diagnosis: IUGR with moderate fetal hypoxia.
