彩色多普勒超声在动脉粥样硬化性肾动脉狭窄诊断中的应用

Application of Color Doppler Ultrasound in Diagnosis of Atherosclerotic Renal Artery Stenosis

目的探讨彩色多普勒超声在动脉粥样硬化性肾动脉狭窄中的诊断价值。方法收集2012年1月至2015年3月我院收治的动脉粥样硬化疾病的患者作为本次研究对象,共计65例,根据患者提供的肾动脉造影结果分为健侧肾动脉和患侧肾动脉。1以肾动脉造影为金标准,计算彩色多普勒超声诊断肾动脉狭窄的敏感度和特异度。2对比健侧肾和患侧肾的彩色多普勒超声指标。结果 1彩色多普勒超声诊断动脉粥样硬化性肾动脉狭窄的灵敏度为64.6%(42/65),特异度为86.2%(56/65)。2健侧肾和患侧肾收缩期峰值流速、舒张末期流速及阻力指数差异有统计学意义(P<0.05)。结论本次研究认为彩色多普勒超声诊断动脉粥样硬化性肾动脉狭窄简便、重复性好,具有较好的诊断价值。

Objective To investigate the value of color doppler ultrasound in diagnosis of atherosclerotic renal artery stenosis. Methods The subjects of this research are patients with atheroselerotie disease from January 2012 to March 2015 in our hospital, a total of 65 cases, According to the results of renal arteriography, divided into health renal artery and renal artery disease. Renal artery angiography as the gold standard, to calculate the sensitivity and the specificity of color Doppler ultrasound in diagnosis of atherosclerotie renal artery stenosis. To compare index of color Doppler ultrasound between health renal artery and renal artery disease. Results The sensitivity of color doppler ultrasound in diagnosis of atherosclerotic renal artery stenosiswas 64.6%（42/65）, the specificity was 86.2%（56/65）. Peak systolic velocity, end diastolic velocity and resistance index in health renal artery and renal artery disease had significant difference （P〈0.05）. Conclusion This study considers that color doppler ultrasound in the diagnosis of atheroselerotic renal artery stenosis is simple, reproducible, and it has better diagnostic value.
