摘　　要：目的探讨彩色多普勒超声对老年2型糖尿病（T2DM）患者下肢血管病变的诊断价值及其临床意义。方法选取2010年6月—2013年5月间450例T2DM患者作为观察组，200例健康体检人员作为正常对照组，分别采用彩色多普勒超声进行下肢血管检查，了解2组患者下肢血管病变发生情况，采用SPSS13．0统计软件进行分析。结果观察组下肢动脉粥样硬化斑块形成率为95．6％（430／450），显著高于对照组的26．5％（53／200），χ2=345．85，P〈0．01；病程〈10年T2DM患者下肢血管病变检出率为12．8％（22／172），明显低于病程为10～20年的61．7％（116／188），χ2=90．90，P〈0．01；病程为10～20年的患者显著低于病程〉20年者的100．0％（90／90），χ2=46．52，P〈0．01；T2DM患者随着病程的延长，下肢血管管腔变细，病程≥15年者各动脉管径（股总动脉、股浅动脉、股深动脉、胭动脉、胫后动脉、足背动脉）均显著低于对照组（t值分别为94．64、173．46、103．49、176．33、122．84、103．65，／9均〈0．01）；观察组足背动脉狭窄程度显著重于对照组（χ2值分别为349．93、88．71、13．85、41．12、16．94，P均〈0．01）。结论彩色多普勒超声在T2DM患者下肢血管病变的诊断中具有较高的准确性，且安全可靠、操作简便、重复性高、无创伤、易于接受，能够为该病的治疗提供一定的临床指导。Objective To discuss the clinical significance and diagnosis value of color Doppler ultrasound for lower limbs angiopathy in elderly patients with T2DM. Methods Total 450 elderly patients with T2DM were enrolled into observation group and 200 healthy volunteers into the control group in our hospital between June 2010 and May 2013. The color Doppler ultrasound was performed to estimate the angiopathy of lower Limbs. The data was analyzed and compared be- tween the two groups by using SPSS 13.0. Results The rate of atherosclerotic plaque formation in the observation group was 95.6% （430/450）, significantly higher than 26.5% （53/200） in the control group （ χ2 = 345.85 ,P 〈 0.01 ） ; The detection rate of lower limb vascular lesion was 12.8% （22/172） in the patients with T2DM with a duration less than 10 years,61.7 % （ 116/188 ） in the patients with a duration of 10 - 20 years （ χ2 = 90.90, P 〈 0.01 ）, and 100.0% （90/90） in the patients with a duration over 20 years （χ2 = 46.52, P 〈 0.01 ） ;The difference was statistical significant. The inner diameter of the lower limb vascular in T2DM patients become stenosis, when compared with the control group, the inner diameters of the lower limb arteries （ common femoral artery, superficial femoral artery, deep femoral artery, popliteal ar- tery, posterior tibial artery, dorsal pedal artery） in T2DM patients with a duration of 15 years or more were thinner （t = 94.64,173.46,103.49,176.33,122.84,103.65 ,P 〈 0.01 ）, respectively ; the stenosis of dorsal pedal artery in the ob- servation group was significantly serious than that in the control group（ χ2 = 349.93,88.71,13.85,41.12,16.94, P 〈 0.01, respectively）. Conclusion The color Doppler ultrasound for the diagnosis of lower limb vascular angiopathy in elderly patients with T2DM is receptive, with the advantages of high accuracy and safety, easy to operate, high repeat- ability and noninvasive evaluation. It can provide certain clinical guiding for the treatment of the d
