彩色多普勒超声检查对2型糖尿病患者下肢血管病变的临床意义

Clinical significance of color Dopper ultrasonoscope in the lower limb angiopathy in patients with type 2 diabetic mellitus

目的:探讨2型糖尿病患者下肢动脉血管病变的危险因素,观察糖尿病外周血管病变的形态学特征,寻找早期诊断方法。方法:应用多普勒超声检查2005～2007年在山东医学高等专科学校附属医院住院的106例确诊为2型糖尿病的患者和40例同期住院无糖尿病的患者下肢血管形态、血管壁内-中膜厚度(IMT)、有无斑块、管腔狭窄或闭塞及血流动力学改变,并进行比较。结果:糖尿病患者下肢血管管腔的硬化斑块、狭窄、闭塞的发生率明显高于对照组。结论:彩色多普勒超声成像对糖尿病患者下肢血管的早期诊断、预防及治疗有重要的临床指导意义。

Objective： To explore the risk factors of lower arterial vessels in patients with type 2 diabetic mellitus and observe the morphologic characteristics of the peripheral vascular lesion in diabetic mellitus, then seek the early diagnostic methods. Methods： 106 patients with type 2 diabetic mellitus and 40 patients whithout DM who were hospitalized from 2005 to 2007 were included in this study. The morpha of lower limb vessels, values of vessel intimal-media thickness （IMT）, incidence of the plaque, lumina stenosis or occlusion and the alteration of haemodynamics in those patients were observed by color Doppler ultrasonoscope, then the outcomes were compared between the two groups. Results： The incidence of atherosclerotic plaques, stenosis and obliteration which occured in the type 2 diabetic angiopathy of lower limbs was apparently higher than that of control group. Conclusion： Color Doppler sonography has an important significance of guidance in the lower limb angiopathy in patients with type 2 diabetic mellitus, which provides early diagnosis, prevention and treatment.
