Doppler assessment of the intrauterine growth-restricted fetus.

ABSTRACT

The evaluation of fetal well-being by Doppler velocimetry in cases of intrauterine growth restriction (IUGR) is of great importance as it is very useful in detecting those IUGR fetuses that are at high risk because of hypoxemia. Several Doppler studies initially on fetal arteries and recently on the fetal venous system provide valuable information for the clinicians concerning the optimal time to deliver. Doppler sonography in combination with the other biophysical methods such as cardiotocogram and biophysical profile score should be used in everyday practice for the monitoring and appropriate management of the growth-restricted fetuses. The purpose of this review is to describe the current approaches in Doppler assessment of IUGR fetal circulation.
