目的:探讨彩色多普勒血流显像(CDFI)对糖尿病(DM)下肢动脉病变的诊断价值。方法:对125例DM患者和50例非DM患者进行下肢动脉彩超检查对照,观察其管壁、管腔及彩色血流特点。结果:DM患者下肢动脉硬化斑块、狭窄、闭塞的发生率明显高于对照组,有统计学差异(P<0.01)。斑块以股动脉最常见,而管腔狭窄、闭塞以腘动脉远侧动脉多见。结论:CDFI对DM患者下肢动脉病变的诊断有重要价值。
Objective: To investigate the diagnostic value of color Doppler flow imaging (CDFI) in the diagnosis of diabetic lower extremity arterial disease. Methods: 125 cases of DM patients and 50 cases of non-DM patients with lower extremity arterial ultrasound examination control, observe the characteristics of the wall, lumen and color flow. Results: The incidence of arteriosclerosis plaque, stenosis and occlusion of lower extremities in DM patients was significantly higher than that in control group (P <0.01). Plaque to the femoral artery is the most common, and stenosis, occlusion of popliteal artery distal more common. Conclusion: CDFI is of great value in the diagnosis of lower extremity arterial disease in DM patients.
