|Title:||Fetal And Placental Doppler Velocimetry In Hypertensive Pregnant Women And Perinatal Outcomes According To Gestational Age [dopplervelocimetria Fetoplacentária Em Gestantes Hipertensas E Resultados Perinatais Segundo A Idade Gestacional]|
|Abstract:||To evaluate the pulsatility index of umbilical artery (UAPI) and middle cerebral artery (MCAPI), as well as the umbilical-cerebral pulsatility (UAPI/MCAPI) ratio in fetuses of hypertensive pregnant women and associated adverse perinatal outcomes. MATERIALS AND METHODS: The authors have analyzed UAPI, MCAPI and UAPI/MCAPI ratio in 289 fetuses of hypertensive women, correlating the results with the presence of adverse perinatal outcomes. Results were compared with and without adjustment for gestational age. RESULTS: Apgar score < 7 at the 5th minute was associated with altered outcomes after adjustment for gestational age. The risk for small-for-gestational-age infant increased three times after such adjustment, with statistical significance for all the Doppler parameters. The increase in risk for neonatal hypoxia after adjustment for gestational age was statistically significant for UAPI and UAPI/MCAPI ratio. No increase was observed in the risk for respiratory distress syndrome in the adjusted analysis. A three-time higher risk for perinatal mortality and altered UAPI with statistical significance was observed after adjustment. CONCLUSION: In fetuses of hypertensive pregnant women, UAPI demonstrated better correlations with perinatal outcomes than MCAPI and UAPI/MCAPI ratio. The risk for adverse gestational outcome should be evaluated taking the gestational age into consideration. © Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.|
