Sonographic diagnosis of fetal growth restriction.
Though a number of ultrasonic methods of diagnosing intrauterine growth restriction (IUGR) exist, the combined use of Doppler velocity wave form analysis of fetal vessels and the ultrasonic estimation of fetal weight (or abdominal circumference) appears to be the best method of both identification and evaluation of IUGR. Once identified, the IUGR fetus should undergo serial evaluation every two weeks or on a weekly schedule (or more frequent interval if the clinical situation warrants) with both Doppler velocity wave form studies and biophysical testing. Determination of the optimal time of delivery depends not only on the results of the antenatal testing, but also on the individual clinical situation. Fetal venous Doppler studies may give additional information about the time frame and significance of the IUGR.
