【摘要】 目的　探讨胎儿宫内生长迟缓时 ,其大脑中动脉、肾动脉、胎盘床动脉、脐动脉的血流阻力变化。方法　收集我院 1997年 1月至 1998年 12月期间出生的体重 <2 5 0 0 g的新生儿 177例 ,其中 12例产前进行了彩色多普勒超声测定。结果　 12例出生低体重儿中 ,其中 ,体重 <2 0 0 0 g者 7例 ,其产前多普勒血流参数显示大脑中动脉、肾动脉、脐动脉和胎盘床动脉阻力指标均明显升高。结论　超声多普勒测定对诊断胎儿宫内发育迟缓以及了解胎儿宫内安危情况具有明显价值更多还原

【Abstract】 Objective To evaluate the changes of color Doppler blood flow indices of fetal middle cerebral artery,renal artery,placental artery and umbilical artery in fetal intrauterine growth retardation(IUGR)and change of systol/diastol(S/D) value in umbilical artery. Methods 177 cases of newborn birth weight less than 2500g were collected and 12 cases were analysed with color Doppler ultrasound. Results 12 cases with newborn birth weight <2500g(1600～2475g),among which 7 cases newborn birth weight<2000g.The colour Doppler blood flow indices-pulsatile index,resistant index of fetal middle cerebral artery,renal artery,placental atrery and umbilical artery and S/D value of umbilical artery in these cases increased differently. Conclusion Color Doppler ultrasonography plays an important role in dignosis of IUGR and evaluation of fetal intrauterine status.It should be an important part of perinatal medicine. [更多还原
