![]() In addition, near-infrared spectroscopy 10, 11 was used to check the possible postnatal brain-sparing effect. In the literature, various antenatal and postnatal parameters have been used to diagnose brain sparing. However, studies have reported controversial results regarding whether this adaptive process is a fully protective mechanism 4, 5, 6. Brain sparing is believed to be an adaptive mechanism of growth-restricted fetuses for maintaining sufficient oxygen and nutrient flow to ensure adequate brain growth and development. In an FGR setting, peripheral vascular beds are vasoconstricted, leading to increased right ventricle afterload conversely, cerebral arteries are vasodilated, leading to a decreased left ventricle afterload, thus, increasing the blood supply to the brain 3. ![]() In fetal circulation, most of the right ventricular blood is directed towards the ductus arteriosus and into the descending aorta, while oxygenated and nutrient-rich umbilical vein blood flows through the foramen ovale, into the left ventricle, from which most of the output is directed to the upper body including upper limbs and brain. This phenomenon is known as brain sparing 2. The affected infants redistribute cardiac output in preference for essential organs–in particular, the brain. The etiologies of FGR include chronic hypoxia caused by maternal hypertensive disorder, placental insufficiency, and disproportionate placental perfusion in twin pregnancies 1. In summary, brain-sparing effect may continue during the early postnatal life in SGA infants, and may be a promising marker to detect future adverse neurodevelopmental outcomes.įetal growth restriction (FGR) is a condition in which fetal growth is pathologically reduced. A UBBF/LVCO ≥ 58.2% (3rd interquartile range) was associated with a later need for rehabilitative therapy after discharge. Both a-SGA and s-SGA groups consisted predominantly of infants with higher UBBF/LVCO (%). Left ventricular (LV) stroke volume, LV cardiac output (LVCO), upper body blood flow (UBBF), and UBBF/LVCO ratio (%) were significantly higher in both a-SGA and s-SGA infants than in AGA infants. This retrospective study included 42 small-for-gestational age (SGA) infants, and 1: 2 matched appropriate-for-gestational age (AGA) infants (n = 84) admitted to the neonatal intensive care unit. Here, we assessed the blood flow distribution during the early neonatal period (< 7 days of life) using echocardiography, and evaluated the impact of brain-sparing on postnatal course and neurodevelopmental outcomes.
