2型糖尿病患者足背动脉超声检测的价值评估

Ultrasonography for Dorsalis Pedis Artery Disease in Type 2 Diabetes:Clinical Value

目的应用超声检测2型糖尿病患者足背动脉病变,并评价其临床价值。方法应用二维及彩色多普勒超声检测临床诊断为证明的70例DM患者的足背动脉,并与60例非DM患者做对比分析研究。结果糖尿病组足背动脉粥样硬化病变的发生率较非糖尿病组明显增高(P<0.01)。糖尿病组足背动脉狭窄和闭塞的发生率高于非糖尿病组(P<0.05)。糖尿病组足背动脉舒张期的血流速度较非糖尿病组明显减低(P<0.01)。结论超声检测足背动脉可反映下肢远端小动脉粥样硬化情况,是评估DM患者周围血管病变程度的有效手段之一,对DM患者肢端血管病变的早期诊断、预防和治疗、治疗后的随访有重要的临床价值。

Objective To detect the dorsalis pedis artery（DPA）disease by ultrasonography in type 2 Diabetes Mellitus（T2DM）and assess its clinical value. Methods The DPA disease was detected in 70 cases of T2DM and 60 cases of non- T2DM by 2D and Color Doppler ul- trasonography and a comparative study was made. Results The incidence rate of DPA athemsclerosis in the T2DM group was significantly higher than that in the Non-T2DM group（P〈0.01 ）. The incident rates of stenosis and occlusion in DPA was higher in the T2DM group than those in the Non-T2DM group（P〈0.05）. The diastolic flow velocity of DPA in the T2DM group was slower than that in the Non-T2DM group （P〈0.01）. Conclusion The detection of DPA by ultrasonography can reflect the athemsclerosis of distal lower limb arteries,which is one of the effective measures to evaluate the degree of peripheral vascular disease in diabetic patients, showing an important clinical value in the early diagnosis, prevention, treatment and follow-up of DPA disease.
