The study of the relationship between maternal and perinatal outcome with uterine blood flows using a continuous wave Doppler unit, in hypertensive patients was the aim of our work. One hundred and thirty seven pregnant hypertensive women seen and delivered at the Department of Obstetrics, Santa Maria Hospital, Lisbon, were included in the study. Blood flows were classified as abnormal if and when the systolic/diastolic ratio was > 2.8 and/or a diastolic notch was seen in one or both uterine arteries. The cases were divided in 2 groups (normal/abnormal) according to the uterine blood flow and correlated with maternal and perinatal outcomes. Twenty-three of 26 maternal complications occurred in cases with abnormal uterine artery blood flow; we also found the large majority of perinatal complications within this group (100% perinatal deaths, 88% of the intrauterine growth retardation, 92% preterm deliveries, 93% fetuses with absent or reverted diastolic umbilical flow, 88% cardiotocographic patterns of fetal distress and 84% of the newborns admitted to the neonatal care unit). In conclusion, in pregnancies complicated by hypertension, uterine artery blood flow evaluation by continuous wave Doppler may identify a set of patients needing closer prenatal surveillance.
我们研究的目的是使用连续波多普勒装置，研究高血压患者母体和围产期结局与子宫血流之间的关系。纳入研究的对象为137例在里斯本圣玛丽亚医院产科就诊并分娩的妊娠高血压妇女。当收缩压/舒张压比值>2.8和/或在一侧或双侧子宫动脉中出现舒张期切迹时，血流被分类为异常。根据子宫血流情况将病例分为两组（正常/异常），并与母体和围产期结局进行相关性分析。26例母体并发症中有23例发生在子宫动脉血流异常的病例中；我们还在该组中发现了绝大多数围产期并发症（100%的围产期死亡、88%的宫内生长受限、92%的早产、93%的舒张期脐血流缺失或反向的胎儿、88%的胎儿窘迫胎心监护图形以及84%入住新生儿重症监护病房的新生儿）。总之，在合并高血压的妊娠中，通过连续波多普勒评估子宫动脉血流可能会识别出一组需要更密切产前监测的患者。
