[Clinical value of the fetoplacental ratio]

Scientific interest in the placenta derives not only from its enormous diversity of form and function but also from the unique metabolic, endocrine and immunologic properties. The steady increase in size and weight of the placenta throughout pregnancy has been investigated in the large number of studies. The data obtained from weighing the placenta vary considerably, depending upon how the placenta is prepared. If membranes and mass of the cord are left attached and adherent maternal blood clot is not removed, the weight is increased by nearly 50 percent. In our study we tried to asses the value of the feto-placental ratio and to correlate the weight of placenta with the other data obtained during pregnancy and labour and with outcome of pregnancy. A group of 1010 patients was assessed. The data obtained these patients were correlated with the length of pregnancy, the body weight of the baby and the status of the newborn estimated by Apgar score in 1 and 5 min. The feto-placental ratio was significantly affected by the length of pregnancy and the status of the newborn. Another comparisons were made with the medical illnesses during pregnancy, i. g. H--Gestosis, renal diseases and the cholestasis of pregnancy.
