2型糖尿病下肢血管病变超声诊断的临床应用价值

Clinical value of ultrasonography in lower extremity blood vessel lesion of type 2 diabetes

目的:评价彩色多普勒超声对2型糖尿病(DM)下肢血管病变(LEAD)的诊断应用价值。方法:2型DM患者91例与41例同期住院非2型DM患者进行下肢血管彩色多普勒超声检查对照,并以踝肱压指数(ABPI)对比观察。结果:2型DM动脉硬化为弥漫性或多节段病变,单纯动脉硬化多为血管分叉处局灶性病变,2型DM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,呈显著性差异(P<0.01)。硬化斑块的发生率以股动脉最常见,而管腔狭窄、闭塞率以累及腘动脉以下的远端动脉血管多见,胫前动脉受累最为明显(P<0.05)。结论:彩色多普勒超声是2型DM患者下肢血管病变检查的有效手段,可评估病变部位、阻塞的性质、病变长度以及解剖的异常,对早期诊断、预防及治疗具有重要的临床应用价值。

Objective： To evaluate the diagnostic rate and value of CDFI in the diagnosis of lower extremity blood vessel lesion in type 2 diabetes. Methods： Ninety-one cases of type 2 diabetes patients and 41 cases of nondiabetes patients simultaneously examinated by CDFI and ABPI were observated. Results： Diabetic arteriosclerosis was diffuse or muhisegmental while simple arteriosclerosis showed focal in bifurcation of blood vessel. Blood vessel lesion incidence in type 2 diabetes was significantly higher than control group（P〈0.01）. The rate of arteriosclerotic plaques was highest in femoral artery, stenosis and occlusion were mostly appeared in anterior tibial artery（P〈0.05）. Conclusions： CDFI is an effective method in detecting lower exteremity vasculature in type 2 diabetes patients and evaluating location, character and length of the lesion, and has important clinical values.
