彩色多普勒超声常规检查糖尿病患者下肢动脉的临床意义

目的探讨糖尿病患者常规进行下肢动脉彩色多普勒血管检查的临床意义。方法应用彩色多普勒超声对我院住院的200例糖尿病患者（糖尿病组）和50例非糖尿病患者（对照组）双下肢动脉进行检查,观察血管内径、内膜、有无斑块、狭窄或闭塞情况,进行比较。将糖尿病患者按年龄、病程进行分组,根据超声检查结果进行比较。结果糖尿病组与对照组下肢动脉的超声检查结果分为3种,正常22例（44.0%）vs 18例（9.0%）,内膜粗糙24例（12.0%）vs 16例（32.0%）,斑块158例（79.0%）vs 12例（24.0%）（P〈0.01）;其中糖尿病斑块组与对照斑块组经超声检查又分为3种程度,无狭窄、狭窄、闭塞,但两组差异无统计学意义（P〉0.05）。年龄与下肢动脉硬化发生率呈正相关（rs=0.510,P〈0.01）;年龄与下肢动脉硬化程度呈正相关（rs=0.372,P〈0.01）,糖尿病病程与下肢动脉硬化发生率呈正相关（rs=0.563,P〈0.01）;糖尿病病程与下肢动脉硬化程度呈正相关（rs=0.333,P〈0.01）。结论常规双下肢动脉多普勒超声检查对糖尿病患者下肢动脉病变早诊断、早治疗以及提高生活质量具有非常重要的意义。

Clinical value of color Doppler ultrasound for lower extremity artery in diabetes patients

Objective To investigate the clinical value of color Doppler flow imaging(CDFI) in lower extremity artery disease of diabetes mellitus(DM).Methods 200 patients with DM and 50 patients without DM(contrast group) were included respectively.The vessel diameter,the intrima media thickness(IMT),plaques and degree of arteriosclerosis of all the patients were observed by CDFI and compared.Patients with DM were divided into two groups according to the age and course of disease.Results Three findings in DM group and...
