彩色多普勒超声评价糖尿病足患者下肢动脉病变

目的 探讨下肢动脉病变与糖尿病足之间的关系。方法 超声检查糖尿病足、糖尿病不合并糖尿病足息者和健康对照组各30例，将下肢动脉分为8个节段，二维超声评价管径、内一中膜厚度（IMT）和管径狭窄率，彩色多普勒显像观察血流充盈并测量流速。结果 糖尿病足组息侧与对侧下肢动脉IMT及狭窄程度无明显差异（t检验，P〉0．05）。与对照组相比，糖尿病足组IMT厚，管径狭窄程度重（方差分析，P〉0．05）。结论 糖尿病足患者下肢动脉硬化明显，患侧与对侧病变程度无显著差异。

Color Doppler Ultrasound Evaluation of Lower Extremity Arterial Disease in Diabetic Foot Patients

Objective To analyze lower extremity arterial disease in diabetic foot patients on color Doppler ultrasound.Methods There were three groups:diabetic foot(DF),type 2 diabetic (DM 2),without diabetic foot(NDF) and the control groups and each group contained 30 patients.Each lower extremity arteries were divided into eight segments.The vascular diameter,intima-media thickness (IMT) and the rate of vascular stenosis of each lower extremity arteries were measured on 2-D images.The flow velocities were detected on color flow imaging and pulsed Doppler.Results Bilateral arteries of DF patients had no significant difference (t test,P>0.05).Compared with the DM2 and control groups,DF patient group had thicker arterial wall and worse arterial stenosis (ANOVA,P<0.05).Conclusions The atherosclerosis in the lower extremify arteries was significant and no significant difference was in both sides.
