摘要
目的:应用彩色多普勒超声研究胡桃夹综合征左肾静脉各参数的指标。方法:应用探头频率3.5~5.0MHZ的彩色多普勒超声,观察30例患者左肾静脉内径,血流速度及压力变化情况。结果:30例患者左肾静脉内径均增宽,仰卧位时左肾静脉狭窄部位内径约1mm~2.4mm,狭窄扩张部位近端内径约4mm~8mm,狭窄部位血流速度约120~195cm/s,狭窄扩张部位近端血流速度约25cm/s~45cm/s,压力阶差约6.55~18.49mmHg。结论:彩色多普勒超声可以对左肾静脉进行观察及准确的测量,可以动态的观察左肾静脉血流速度的变化及内径的变化,对胡桃夹现象的诊断具有重要意义。
Objective:Objective:To research the association of NCP by Color Doppler Ultrasound.Methods:30 patients were checked by Color Doppler ultrasound(3.5~5.0MHZ)to observation the change of left renal vein s diameter,velocity and Pressure.Result:Left renal vein s diameter of 30 patients were broadening,the diameter of narrow parts were 1~4 mm,the diameter of expansion parts were 8~15mm,the velocities of narrow parts were 120~195cm/s,the Velocities of expansion parts were 25~45 cm/s,pressure were 6.55~18.49 mmHg.Conclusion:NCP could be observed by Color Doppler Ultrasound intuitive and had Important Significance.Color Doppler Ultrasound is important to diagnosis NCP
