摘　　要：目的:探讨彩色多普勒检测过敏性紫癜(HSP)患儿肾血流变化的临床意义。方法:用彩色多普勒超声仪检测35例HSP患儿肾血流动力学变化,以30例健康儿童作为对照组,同时检测HSP患儿尿常规、尿微量白蛋白。结果:HSP患儿肾血流频谱为高速高阻型,肾主动脉、叶间动脉、弓状动脉的收缩期最大峰值流和阻力指数均高于正常对照组。35例HSP患儿中彩超肾血流异常31例(88.6%),尿常规异常8例(22.9%),尿微量白蛋白异常25例(71.4%)。检测的敏感性由高到低依次为彩超肾血流、尿微量白蛋白、尿常规。结论:多普勒肾血流检测是早期发现过敏性紫癜患儿肾损害的敏感指标。Aim: To investigate the clinical implication of renal hemodynamic changes in children with Henoch-Schnlein purpura.Methods:Color Doppler ultrasound was used to detect renal hemodynamic changes in 35 cases of Henoch-Schnlein purpura,whose urine routine,microalbuminuria were also tested,and 30 healthy children served as control.Results: Frequency spectra showed high velocity and resistance,and maximum crest flow rate,resistant index in systolic phase of main renal arteries,interlobar renal arteries and arcu...
