彩色多普勒分析糖尿病足的下肢动脉病变

Analysis of Lower Extremity Arterial Lesions of Diabetic Foot by Using Color Doppler

目的观察糖尿病足与下肢动脉病变的关系。方法彩色多普勒观察我院门诊、住院的40例确诊为糖尿病足的患者与60例正常组患者,比较两组下肢动脉形态、内径、血管壁内膜-中膜厚度(IMT)、有无斑块、狭窄、闭塞、侧支循环形成及血流动力学改变。结果(1)糖尿病足患者下肢血管管腔内的硬化斑块、狭窄、闭塞的发生率明显高于对照组;(2)硬化斑块以股动脉最多见,其中以股总动脉及分叉处更明显。管腔狭窄、闭塞的发生率胫前动脉足背动脉最为明显。结论糖尿病足患者硬化、斑块、狭窄、闭塞率明显高于对照组,并且IMT增厚明显。

Objective To observe the relationship between the diabetic foot and lower extremity arterial lesions. Methods We ob- served by using Color Doppler 40 out-patients and hospitalized patients diagnosed as diabetic foot,and the lower extremity arterial morphology, diameter and vessel wall intima-media thickness（IMT）, plaques,stenosis and occlusion, collateral circulation formation and hemodynamic changes in 60 cases of normal controls in our hospital. Results （1）The incidence of the plaque,stenosis or occlusion within the lower extremity vascular lumen in the patients with diabetic foot was significantly higher than that of the controls. （2）The most were femoral artery plaques which were the most obvious at the femoral artery and its furcation. Conclusion The incidence rates of sclerosis,plaque, stenosis and occlusion in the patients with diabetic foot are significantly higher than those of the controls,and the IMT thickening is apparent but the change in the blood flow velocity is not necessarily obvious.
