2型糖尿病下肢血管病变超声诊断的临床应用价值

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。

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

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 multisegmental 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.
