摘　　要：目的:探讨彩色多普勒超声检测在糖尿病患者颈动脉硬化诊断过程中的临床应用价值。材料与方法:选取2013年6月至2014年10月在我院就诊的2型糖尿病(DM)患者(DM组)108例,另选取同期门诊健康体检者100例作为对照组,比较两组颈动脉斑块存在情况、颈动脉内膜中层厚度(IMT)以及血流动力学的差异。结果:通过彩色多普勒超声检测颈动脉IMT[(1.16±0.15)mm]较对照组[(0.77±0.10)mm]明显增厚(P<0.05);DM组斑块检出率为83.33%,对照组检出率为26.00%,两组比较,DM组斑块检出率明显增高(P<0.05);血管轻度狭窄(狭窄<50%),彩色多普勒超声检测无血流动力学改变;血管狭窄明显(狭窄>50%)时,与对照组比较SPV与EDV加快,狭窄远端的血流频谱低平,峰值流速减低,RI和PI均增高,表现出明显的血流动力学改变(P<0.05)。结论:彩色多普勒超声检测在糖尿病颈动脉硬化过程中能够清晰的显示颈动脉内-中膜厚度和形态以及血流动力学,具有很高的临床应用价值。Purpose： To analyze the application of color Doppler ultrasonography in diagnosis ofdiabetic carotid scle- rosis. Materials and Methods： 68 hospitalized type 2 diabetes patients （ as an observation group） and in 73 healthy individu- als （as a control group） were compared and analyzed. Results： The tunica intima and media of carotid were significantly thic- ker in observation group [ （ 1.16±0. 15）mm] than in control group[ （0. 77 ±0. 10）mini （ P 〈0. 05）. The incidence rate of plaques was significantly higher in observation group than in control group （ 83.33% vs 26. 00% , P 〈 0. 05 ）. The change in haemodynamics was more obvious in patients with mild and severe stenosis （ 〉 50% ） , the blood flow was rapider, increased flow rate in terminal diastolic phase, and increased PI and RI, in observation group than in control group （ P 〈 0. 05 ）. Con- clusion： Color Doppler uhrasonography can accurately detect the plaques, nature and vascular lesion of carotid sclerosis.
