目的探讨彩色多普勒超声对2型糖尿病(T2DM)患者下肢动脉病变的诊断价值。方法选择T2DM患者320例(A组)和无糖尿病患者100例(B组),采用彩色多普勒超声检查单侧下肢动脉血管形态、血管壁内-中膜厚度(IMT)、血管内斑块形成、管腔狭窄、闭塞及血液动力学改变情况。结果 A组患者下肢动脉IMT增厚合并斑块、狭窄和闭塞的发生率明显高于B组(66.3%vs.10.0%、9.4%vs.1.0%和5.0%vs.0.5%)(P<0.05)。结论彩色多普勒超声对T2DM患者下肢动脉病变的早期诊断有临床价值。
Objective To investigate the diagnostic value of color Doppler ultrasound in lower extremity arterial disease in type 2 diabetes mellitus (T2DM). Methods A total of 320 patients with T2DM (group A) and 100 patients without diabetes (group B) were selected. Color Doppler echocardiography was used to examine the morphology of arterial vessels in the unilateral lower extremities, the intima - media thickness (IMT) Formation, stenosis, occlusion and hemodynamic changes. Results The incidence of IMT thickened with plaque, stenosis and occlusion in group A was significantly higher than that in group B (66.3% vs. 10.0%, 9.4% vs.1.0% and 5.0% vs.0.5%) (P <0.05 ). Conclusions Color Doppler ultrasound has clinical value in the early diagnosis of lower extremity artery disease in T2DM patients.
