114例动脉粥样硬化性肾动脉狭窄的彩色多普勒超声诊断

目的探讨彩色多普勒超声诊断动脉粥样硬化性肾动脉狭窄（ARAS）的价值，以及冠状动脉（简称冠脉）造影患者中ARAS的患病率及其相关因素。方法114例患者肾动脉彩色多普勒超声检查后同时行冠脉造影及肾动脉造影，将彩超结果与肾动脉造影结果行对照分析。结果彩色多普勒超声诊断肾动脉病变及狭窄的敏感性为92％，特异性为96％，多元Logistic回归分析表明：仅年龄、顽固性高血压、颈动脉粥样斑块、冠脉是ARAS的独立预测因素。结论彩色多普勒超声是诊断肾动脉狭窄的一种简便、有效且重复性好的方法。

Purpose of color Doppler flow imaging of atherosclerosis of the renal artery stenosis （ARAS） and the value of coronary artery （coronary） ARAS in contrast with the prevalence rate and related factors. Methods 114 patients with renal artery color Doppler ultrasound examination at the same time after coronary angiography and renal angiography, color Doppler ultrasound results and renal angiography results ofthe control line. Results Color Doppler ultrasonic diagnosis of renal artery diseaseand narrow the sensitivity of 92% and specificity of 96%, pluralism Logistic regression analysis showed that only age, intractable high blood pressure, carotid atherosclerosis, coronary 3 ARAS-vessel is the independent predictors. Conclusion Color Doppler ultrasound diagnosis of renal artery stenosis is a simple, effective and reproducible method.
