[The role of umbilical Doppler in the monitoring of pregnancy].
Doppler recordings from the umbilical cord in utero explores the placental reserves and fetal well being. Compliance with the technical conditions of performance ensures reliability of the determination. This examination predicts the state of the child at birth, particularly in cases of delayed intra-uterine growth, maternal hypertension or gestosis, and in cases of twin pregnancies. The change is maximum when the umbilical diastolic flow disappears. In the absence of any pathological context, a congenital or chromosomal abnormality should be considered and the fetal karyotype should be determined. Follow-up is carried out during hospitalization, and the decision on whether to extract the fetus is based on cerebral Doppler recordings and a detailed analysis of the fetal heartbeat.
