Diastolic Deceleration Area in Late-onset FGR

Diastolic Deceleration Area (DDA) in Late-onset Fetal Growth Restriction (FGR)

DDA is a new Doppler parameter aiming to assess fetal well-being in-utero. Late-onset FGR is a specific subgroup of fetuses where the clinical application of this Doppler modality could play an essential role in detecting hypoxia, anemia, and other adverse neonatal outcomes.

Inclusion Criteria:

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