Diastolic Deceleration Area in Early-onset FGR

Diastolic Deceleration Area in Severe Early-onset Growth Restriction of the Fetus

DDA is a new Doppler parameter aiming to assess fetal well-being in-utero. Early-onset SGR is a specific subgroup of fetuses where the clinical application of this Doppler modality could play an important role in the detection of hypoxia, anemia, and brain-sparing.

Inclusion Criteria:

• absence of fetal abnormalities and/or genetic conditions;
• single pregnancy;
• fetal growth restriction (FGR) < 10%, according to the INTERGROWTH 21st nomograms, appearing before 32nd week of gestation

Exclusion Criteria:

• documented fetal abnormalities and/or genetic conditions in the course of the pregnancy;
• multiple pregnancy;
• absence of fetal growth restriction (FGR) < 10%, according to the INTERGROWTH 21st nomograms before 32nd week of gestation
