[Pulsatility indexes of fetal middle cerebral artery and umbilical artery for predicting intrauterine fetal growth retardation].
OBJECTIVE
To evaluate the role of fetal cerebral and umbilical blood flow for predicting intrauterine fetal growth retardation (IUGR).


METHODS
Doppler ultrasonography was used to study pulsatility indexes (PI) of the fetal middle cerebral artery (MCA) and umbilical artery (UA) in 84 normal late pregnancies and 31 IUGR cases.


RESULTS
MCA PI were significantly lower in IUGR fetuses than that of normal fetuses (P < 0.01). UA PI and UA PI/MCA PI ratio were higher in IUGR group than that of normal group (P < 0.01). The sensitivities of MCA PI, UA PI and UA PI/MCA PI ratio for predicting IUGR were 80.64%, 70.96% and 87.09% respectively at the cut off level with 2 standard deviation (SD). The specificities were 94.05%, 88.90% and 97.61% respectively.


CONCLUSIONS
Doppler ultrasonography for predicting IUGR was a practical and sensitive method.
