P83Fetal hemodynamic profile in pregnancies with absent or reversed end-diastolic velocity waveforms in the umbilical artery that presented fetal death

Authors


Abstract

Background

A description of the fetal hemodynamic profile in pregnancies with absent or reversed end-diastolic velocity (AREDV) that presented fetal death.

Material and methods

Between 1997 and 2000, 107 high risk pregnant women with AREDV were followed by the Fetal Surveillance Unit. Seventeen cases that presented fetal death (FD) were submitted to Dopplervelocimetry of the umbilical artery (UA), descending thoracic aorta (DTA), middle cerebral artery (MCA) and ductus venosus (DV).

Results

The results are shown in the table:1

Conclusions

The results show severe fetal hemodynamic profile abnormalities, revealed by Doppler studies conducted in AREDV cases that presented fetal death.
