目的对糖尿病患者足背动脉进行高频彩色多普勒超声探查,探讨其在糖尿病足背动脉病变的临床应用价值。方法 200例糖尿病患者作为糖尿病组,200例正常就诊者作为对照组,比较分析两组血管形态、血管壁内-中膜厚度(IMT)、有无斑块、管腔内径狭窄情况及是否闭塞,并观察血流动力学改变情况。结果糖尿病组单纯IMT增厚、低回声或强回声斑块、狭窄及闭塞发生率均高于对照组,差异均具有统计学意义(P<0.05)。结论糖尿病患者采用高频彩色多普勒超声检测足背动脉能在早期发现足背动脉病变,反映足背动脉粥样硬化程度,对糖尿病足背动脉病变有重要的临床应用价值。
Objective To investigate the clinical value of dorsalis pedis artery in diabetic patients by high-frequency color Doppler sonography. Methods 200 cases of diabetic patients as diabetic group and 200 cases of normal patients as control group were included in this study. The blood vessel morphology, intima-media thickness (IMT), plaque, lumen stenosis and occlusion were compared between the two groups. Hemodynamic changes were observed. Results The IMT thickening, hypoechoic or hyperechoic plaque, stenosis and occlusion in diabetic group were significantly higher than those in control group (all P <0.05). Conclusion The detection of dorsalis pedis artery by early detection of the dorsalis pedis artery by high-frequency color Doppler ultrasound in diabetic patients may reflect the degree of dorsalis pedis artery atherosclerosis. It has important clinical value in the diagnosis of diabetic foot dorsal artery.
