Valoarea de prognostic perinatal a velocimetriei Doppler pe vasele circuitului utero-placento-fetal la fetuşii cu RCIU

Abstract

Summary. Intrauterine fetal growth retardation (IFGR) shows a current perinatal issue leading to multi-perinatal complications, affecting the development of the fetus and determining long-term morbidity. Dopplerography introduction allowed the opportunity to make repeated noninvasive studies of utero-fetal-maternal hemodynamics. Compared with other methods of fetal monitoring, dopplerography supposed to be more sensitive in establishing early compromise of fetal status and determine timing for induction of labor. The purpose of this study is the analysis of presented gravity in changes taking place in the utero-placento-fetal circulation in fetuses undergoing IFGR and blood fl ow disturbance effects of different degree of perinatal outcomes. A study was conducted of 70 pregnancies between 24.0-36.6 weeks’ gestation term amenorrhea resulting in premature birth accompanied by IFGR. Studied tasks were distributed in the degree of circulatory insuffi ciency according to classifi cation proposed by M. Medvedev. In the presented study a predominance of pathological vascular fl ow with a high degree of involvement was established in tasks that term IFGR started early with a moderate attenuation index with advancing gestation period. Uterine artery dopplerography changes are present in almost half of all cases resulting in premature birth, while preeclampsia is very common in cases of fetal retardation. After the results of this study it was found that dopplerography placental circulation may be an effective method for predicting multiple complications in pregnancy and fetuses were subjected IFGR more likely to be hospitalized in intensive care unit and to develop obstetric and neonatal complications.
