摘　　要：目的:应用彩色多普勒超声诊断左肾静脉压迫综合征。方法:47例无症状性、体位性或运动性血尿或蛋白尿青少年患者为左肾静脉压迫组,23例尿检正常青少年为对照组,超声测量左肾静脉狭窄段和近肾门段的内径及峰值流速,并计算内径比值(近肾门段内径/狭窄段内径)。结果:左肾静脉压迫组的左肾静脉近肾门端内径与狭窄段内径的比值为4.13±2.34,而对照组为2.16±0.56;左肾静脉压迫组狭窄段内径和流速分别为(0.16±0.07)cm/s和(83.3±37.2)cm/s;对照组分别为(0.24±0.09)cm/s和(43.1±10.8)cm/s,两组差异有显著性统计学意义(P<0.05)。左肾静脉近肾门段内径与狭窄段内径比值>4.0,即可诊断左肾静脉压迫综合征。结论:彩色多普勒超声对诊断左肾静脉压迫综合征是十分有用的影像学方法。Objective ： To investigate the diagnose nutcracker syndrome with color Doppler flow imaging. Methods：Doppler sonographic findings in 47 children with orthostatic proteinuria or idiopathic hematuria and in 23 healthy control subjects were compared. The peak velocity, anteroposterior diameter and anteroposterior diameter ratio （hilar segment/aortomesenteric segment） were measured in the left renal vein. Results： The anteroposterior diameter ratio of the 2 segments were 4.13 ±2.34 in the patient group and 2.16 ±0.56 in the control. The anteroposterior diameter and the peak velocity in the aortomesenteric segment were （0.16 ± 0.07）cm/s and （83.3 ± 37.2）cm/s in the patient group and （0.24 ＋ 0.09） cm/s and （43.1 ± 10.8）cm/s in the control, with significant difference in between （P 〈 0.05 ）. The value of the anteroposterior diameter ratio for diagnosing nutcracker syndrome was greater than 4.0. Conclusion： Color Doppler flow imaging of the left renal vein may be a useful imaging tool in the diagnosis of patients with nutcracker syndrome.
