Abstract
Introduction
Doppler study of the uteroplacental circulation was first suggested as a method of pregnancy assessment by Campbell and colleagues,¹ who observed that Doppler flow velocity waveforms (FVW) were abnormal in pregnancies complicated by pregnancy-induced hypertension (PIH) and intrauterine growth retardation. In recent years a number of Doppler ultrasound studies of the uteroplacental circulation have confirmed the original observation that increased impedance to flowin these vessels is associated with an increased risk for subsequent development of pre-eclampsia and/or FGR.2. IUGR is thought to be the consequence of impaired trophoblastic invasion of the maternal spiral arteries and the physiological reduction in vascular resistance in the uteroplacental circulation 1,3-7.
It is essential to accurately predict intrauterine growth restriction to facilitate monitoring and preventive treatment so that better maternal and perinatal outcome is achieved8. Women with normal uterine artery Doppler results are unlikely to develop preeclampsia, FGR or placental abruption and therefore do not necessarily need antenatal follow-up that is as close as that required in women with abnormal uterine artery Doppler findings9.
