目的探讨彩色多普勒超声检查对糖尿病下肢动脉病变的诊断价值。方法选取2型糖尿病患者40例(观察组),对照组为同期在我院住院的非糖尿病者28例。对两组患者进行双下肢动脉彩色多普勒超声检查,观察其血管形态、内-中膜厚度、粥样硬化斑块、管腔狭窄及血流动力学改变情况。结果观察组下肢动脉内膜增厚、斑块、血管狭窄发生率高于对照组(P<0.05),观察组股浅动脉、腘动脉、胫前动脉管径小于对照组(P<0.05)。结论彩色多普勒超声对下肢动脉病变诊断具有灵敏度高、直观性好、可重复、无创伤等优点,可作为糖尿病患者定期常规检查项目之一。
Objective To investigate the diagnostic value of color Doppler ultrasonography in the diagnosis of diabetic lower extremity arterial disease. Methods Forty patients with type 2 diabetes mellitus (observation group) were selected. The control group consisted of 28 non-diabetic patients hospitalized in our hospital during the same period. Two groups of patients underwent double lower extremity arterial color Doppler ultrasound examination of vascular morphology, intima-media thickness, atherosclerotic plaque, stenosis and hemodynamic changes. Results The incidence of intima thickening, plaque and stenosis of lower extremity in observation group was higher than that in control group (P <0.05). The diameter of superficial femoral artery, popliteal artery and anterior tibial artery in observation group was smaller than that in control group (P <0.05). Conclusion Color Doppler ultrasonography has the advantages of high sensitivity, good intuition, repeatability and noninvasiveness in diagnosis of arterial disease of lower extremity. It can be used as one of regular routine examination items in diabetic patients.
