IUGR AND SGA: PATHOPHYSIOLOGY Sometimes situations arise that cause fetal growth restriction, resulting in fetuses small for gestational age (SGA) and fetuses with intrauterine growth restriction (IUGR). SGA and IUGR are not synonymous terms. VISIT OUR FREE WEBSITE AND FIND THE VIDEO PDF, PODCAST, QUIZ QUESTIONS... https://aulaginecologia.com/profesion... SGA: small fetus that maintains a normal growth curve. IUGR: fetus that does not reach its expected growth potential in the uterus due to genetic or environmental factors. HOW IS FETAL GROWTH MEASURED? Fetal size is estimated using ultrasound biometry. Based on measurements of the biparietal diameter, head circumference, abdominal circumference, and femur length, and considering whether it is a singleton or multiple pregnancy and the fetal sex, the estimated fetal weight (EFW) is calculated. The diagnosis of growth restriction is based on the discrepancy between the fetal biometric measurements and those expected for a given gestational age. Traditionally, it is defined as a weight below the 10th percentile (p10) on a single-fetus growth chart, which would already mean that the fetus is, at least, small for gestational age (SGA). However, the percentile definition is clinically practical and, by itself, does not distinguish between a constitutionally small fetus, which reaches its normal growth potential without a greater risk of adverse outcomes (SGA), and a similarly small fetus whose growth potential is restricted and which has a higher risk of perinatal morbidity and mortality (IUGR). Distinguishing between a constitutionally small fetus and a fetus with pathological restriction is the first challenge for the obstetrician, as this will modify the monitoring and delivery time. We need to distinguish between a small fetus with low risk and a small fetus with higher risk. In clinical practice, when a fetus with an estimated gestational weight (EGD) below the 10th percentile is identified, fetal growth and physiology are monitored over time. Normal fetal anatomy, a good growth trajectory, normal Doppler ultrasound, and normal amniotic fluid suggest a constitutionally small fetus, or one minimally affected by uteroplacental insufficiency or other pathological factors that may impede proper fetal growth (good prognosis).
