摘　　要：本文以胎儿脐动脉收缩期血流速度峰值比舒张末期血流速度峰值(S/D)做为胎儿-胎盘循环阻力的超声学指标,以胎盘三级绒毛的微小动脉数目做为解剖学指标,对22例妊高征及8例正常妊娠妇女的胎儿脐动脉多普勒血流频谱及胎盘病理进行了观察。结果发现:A 组(妊高征脐动脉多普勒血流频谱 S/D>3)胎盘微小动脉数目(3.1±8.1个/视野)明显少于 B 组和 C 组(脐动脉多普勒血流频谱S/D<3)的微小动脉数(6.4±6.5个/视野、7.2±3.4个/视野),P<0.05。且 A 组新生儿预后比 B 组和C组差(P<0.05)。认为脐动脉多普勒血流频谱 S/D 值与胎盘形态学密切相关。We have studied umbilical artery Doppler blood- flow velocity waveform and placental pathology in 22 eases EPH-syndrome and 8 cases normal pregnancy. In this study,the ratio between the peak of the sys- tolic bloodflow velocity and the bloodflow velocity at the end diastolic phase(S/D)acted as a ultrasono- graphic index of fetal-placental circulation resistane and the number of microartery in tertiary villi acted as a anatomical index.The results showed that the num- ber of placental microartery(3.1±8.1/visual field)of A group(S/D of umbilical artery Doppler bloodflow velocity waveform Of EPH—syndrome>3)was much less than those(6.4±6.5/visual field,7.2±3.4/vi- sual field)of the B and C group(S/D of umbilical artery Doppler bloodflow velocity waveform of EPH— syndrome<3),P<0.05.The prognosis of neonates in A group was worse than that of the B and C group(P <0.05).The conclusion was that the S/D value of umbilical artery Doppler bloodflow velocity waveform is closely associated with placental morphology and can reflect the condition of fetal-placental blood cir- culation and can be a uasful metho to predict the fetal prognosis.
