Renal Artery Doppler Studies in Intrauterine Growth Restriction Fetuses

Abstract

Intrauterine growth restriction (IUGR) is a condition in which the fetus fails to achieve its genetically determined growth potential and is associated with increased perinatal morbidity and mortality. Doppler ultrasonography has become a crucial non-invasive tool for monitoring fetoplacental and fetal circulations, providing valuable information on hemodynamic adaptation. Among these, renal artery Doppler studies offer insights into fetal redistribution of blood flow and kidney perfusion, which may reflect the severity of growth restriction.
