Fetal ductus venosus doppler velocimetry in intrauterine growth restriction in relation to adverse perinatal outcome

To investigate duetus venosus blood flow in growth restricted fetuses and to relate the Doppler results to perinatal outcome.

Yöntem

A cohort study among 20 pregnant women clinically diagnosed as suffering from intrauterine growth restriction was conducted. Doppler velocity waveforms were recorded from fetal duetus venosus every two-week and the last results were evaluated in relation to mode of delivery. APGAR score, birth weight, fetal blood pH, length of hospitalization, NICU stay, and perinatal death.

Bulgular

Doppler flow studies demonstrated evidence of reduced velocity in more than 90% of cases in terms of time average, peak systolic, peak diastolic, and A wave velocities among fetuses clinically diagnosed as intraulerine growth restriction. Reduced ductus venosus flow velocities were significantly correlated with low 1 minute APGAR scores, low hirth weights, and fetal acidemia but were not significantly correlated with mode of delivery, length of hospitalization, and NICU stay. Lost and reversed A waves were recorded previously in two cases with perinatal death.

Sonuç

Reduced ductus venosus flow velocities are significantly correlate with the evidence of redistribution of oxygenated fetal blood flow and adverse perinatal outcome. Lost and reversed A wave are significantly correlate with high perinatal mortality rale.
