Abstract

Objective: The purpose of this study was to determine the relationship between fetal cardiovascular hemodynamics and neurodevelopmental outcome in infants born before 32 gestational weeks with placental insufficiency. Study design: Seventeen fetuses that underwent Doppler ultrasonography within 24 hours before delivery were included in this prospective cross-sectional study. Placental histology was examined. Multiple inflammatory markers and vascular endothelial growth factor (VEGF) and its receptor were analyzed from umbilical cord serum. Neurodevelopmental outcome was assessed by Griffiths scales at 1 year of corrected age. Results: Infants with suboptimal outcome (n = 7) had higher umbilical artery, ductus venosus, and inferior vena cava pulsatility index values (P < .05) and lower weight-indexed cardiac outputs (P < .05) than infants with normal outcome (n = 10). Placental histology and serum revealed no inflammation. VEGF values were similar among all infants. Conclusion: In placental insufficiency with delivery before 32 gestational weeks, suboptimal neurodevelopment was related to decreased fetal weight-indexed cardiac output and increased systemic venous pressure.
