태아 제대동맥 혈류속도 파형에 따른 주산기 예후 = Fetal Umbilical Artery Flow Velocity Waveforms and Subsequent Perinatal Outcome

다국어 초록 (Multilingual Abstract)

Fetal umbilical artery blood flow waveforms were recorded in 453 pregnancies within 2 weeks of delivery. We measured the systolic/diastolic (A/B)ratios and classified the populations into two groups (Group I; A/B ratio mean + 2 SD, Group II; A/B ratio > mean ±2SD). Group IIwas associated with shorter gestational age at delivery, lower birth weighted infant, and more frequent number of preterm delivery. Also, the Group showed significantly higher incidence of pregnancy-induced hypertension, fetalgrowth retardation, and postterm pregnancy. With respect to the ot독 parameters of perinatal outcome(e.g., 1-and 5 minute Apgar score, stillbirth, fetal distress to cesarean section, and admission to neonatal intensive care unit), there was also a higher rate of adverse outcome in Group II, and similar findings were observed in preterm deliveries. The results of this study showed high specificity and negative predictive value of fetal umbilical artery A/B ratio for small for gestational age, 5-minute Apgar score, stillbirth, fetal distress to cesarean section, and admission to the neonatal intensive care unit. As a conclusion, this study suggested that Doppler umbilical artery velocimetry may be useful in predicting the pregnancy outcome.
