Prediction of Intrauterine Growth Restriction in High Pulsatility Index of Uterine Artery | Chapter 02 | Current Trends in Medicine and Medical Research Vol. 3
Introduction: Intrauterine growth restriction is a significant cause of neonatal mortality. The uterine artery Doppler waveform becomes transformed into a high flow with low resistance at 22-24 weeks. The apt way to reduce intrauterine growth restriction is to identify the antenatal factors, which ascertain the uterine milieu and nutrient bioavailability. This chapter highlights the relation between abnormal uterine artery flow and resultant fetal growth restriction in a tertiary care center. Presence of high pulsatility is a significant risk factor for early onset IUGR as compared to late onset IUGR. Abnormal Doppler waveforms within the uterine arteries are indicative of elevated resistance. The perfusion at the trophoblast-maternal interphase is high velocity, low volume and intermittent, resulting in intrauterine growth...
