FUNCTIONAL RELATIONSHIP BETWEEN PLACENTAL MASS AND FETAL WEIGHT IN MACROSOMIA

This study was devoted to determining the functional relationship between placental morphometric parameters (mass, surface area, and volume) and fetal birth weight in pregnancies complicated by macrosomia. A comparative clinical observation was conducted between macrosomia and physiological pregnancy groups. According to the results, in cases of macrosomia, placental mass increased on average by 15–17%, surface area by 18–22%, and volume by 14–16%. Correlation analysis demonstrated a moderate relationship between placental volume and fetal weight (r=0.52), and between placental mass and fetal weight (r=0.49). However, in some cases, a small placenta with a large fetus and a large placenta with normal birth weight were observed. These findings confirm that the functional efficiency of the placenta is more important than its morphometric size.
