Doppler ultrasonography of the middle cerebral artery was performed on 17 fetuses that were small for gestational age at the time of delivery. Results were compared with a group of 25 fetuses that had a normal weight for gestational age at the time of delivery. Despite a significant difference in fetal weight and systolic/diastolic ratio of the umbilical artery between the two groups, no difference was found in either the systolic/diastolic ratio or in the Pourcelot index of the middle cerebral artery. This may reflect a protective effect on the brain circulation in the small-for-gestational-age fetus.
对17例分娩时小于孕周的胎儿进行了大脑中动脉多普勒超声检查。将结果与25例分娩时体重符合孕周的胎儿组进行比较。尽管两组胎儿体重及脐动脉收缩/舒张比存在显著差异,但大脑中动脉的收缩/舒张比或普尔塞洛指数均未发现差异。这可能反映了对小于孕周胎儿脑循环的保护作用。
