摘　　要：目的:探讨下肢动脉硬化闭塞症(ASO)彩色多普勒超声(CDU)整体分级标准与临床分期标准的相关性及临床意义,并对动脉病变程度做出综合评价。方法:应用彩色多普勒超声将125例ASO患者根据闭塞节段、数量、狭窄程度及侧支数量的不同分为轻、中、重3组,并利用Spearman等级分析方法使之与临床分期进行相关性研究。结果:CDU整体分级的ASO轻度、中度、重度各组患者,临床表现也逐渐加重,与依据临床分期的一期、二期、三期判定标准呈正相关。Spearman等级分析结果显示2组间存在相关性(rs=0.7972,P<0.01);彩色多普勒超声对ASO的整体分级与临床分期具有较好的一致性。结论:彩色多普勒超声对ASO的整体分级考虑了动脉局部狭窄程度、狭窄范围、闭塞节段及侧支动脉等多因素对临床症状的影响,更客观地划分病变程度,并显示了与临床分期有较好的一致性。Objective To investigate the correlation and the clinical significance between the overall classification on color Doppler ultrasound and the clinical stages of atherosclerosis obliterans （ASO）,and evaluate the extent of arterial lesions comprehensively.Methods 125patients of ASO,who were divided into three groups of mild,moderate and severe with Color Doppler ultrasound according to differences of occlusion,quantity,degree of stenosis and collateral number,were analyzed with clinical stages,then their associations were studied with Spearman rank analysis.Results The clinical manifestations of ASO patients who were divided into three groups of mild,moderate and severe according to overall classification on color Doppler ultrasound were respectively gradually serious,which had positive correlations with the stages ofⅠ,ⅡandⅢaccording to clinical stages.Spearman rank analysis showed that the correlation coefficients（rs）was 0.797 2between two groups（P〈0.01）,there was good consistency between the overall classification on color Doppler ultrasound and the clinical stagesof ASO.Conclusion The overall classification of ASO on color Doppler ultrasound has considered impact of many other factors on the clinical symptoms,such as the level of the local narrow,narrow scope,segments of occlusion and collateral arteries,which divids the lesions more objectively,shows good consistency with the clinical stages.
