Aloka Color-Doppler, model SSD-860, was used to observe the blood velocity waveforms in the umbilical artery and in the fetal descending thoracic aorta in 139 normal pregnant women from 16th to 40th week and 30 patients suffering from pregnancy induced hypertension (PIH syndrome). The ratio of systolic to diastolic peak flow (A/B) reflected the fetoplacental vascular resistance and peripheral resistance. The results demonstrated that the placental resistance in PIH syndrome and IUGR were much higher than that in normal pregnancy. The placental resistance decreased when patients condition improved after treatment and vice versa. This suggests that fetal blood velocity waveforms (FVW) is of great value in the intensive monitoring of IUGR fetuses. The blood velocity FVW was also of great value in evaluating the curative effects on PIH patients.
使用阿洛卡彩色多普勒SSD - 860型仪器，对139例孕16周到40周的正常孕妇以及30例妊娠高血压综合征（PIH综合征）患者，观察其脐动脉和胎儿降主动脉的血流速度波形。收缩期与舒张期峰值血流之比（A/B）反映了胎儿胎盘血管阻力和外周阻力。结果表明，PIH综合征和胎儿宫内生长受限（IUGR）患者的胎盘阻力远高于正常妊娠者。治疗后病情改善时胎盘阻力下降，反之亦然。这表明胎儿血流速度波形（FVW）在IUGR胎儿的严密监测中具有重要价值。血流速度FVW在评估PIH患者的治疗效果方面也具有重要价值。
