2型糖尿病患者下肢动脉病变的彩色多普勒观察

A STUDY OF VASCULAR LESIONS IN THE LOWER EXTREMITIES IN TYPE 2 DIABETIC MELLITUS BY COLOR DOPPLER FLOW IMAGING

为探讨彩色多普勒超声对 2型糖尿病下肢动脉病变的诊断价值 ,应用彩色多普勒超声对 10 2例 2型糖尿病患者下肢动脉进行检查 ,并与 2 0例正常组对照 ,测量血管内 中膜厚度 (IMT)、斑块大小、血管内径、血管的内径狭窄率、狭窄口的峰值流速增加率 ,并观察频谱形态。结果表明 ,2型糖尿病患者下肢血管病变彩色多普勒超声检出率高于临床表现 ,并可通过以上指标的测定 ,对病变程度作出判断 ,为临床提供定量诊断的依据。

To explore the clinical value of the color Doppler flow imaging (CDFI))in diagnosis of vascular disease in the lower extremities of patients with type 2 diabetic mellitus(2DM), 102 patients with 2DM and 20 normal controls were included in this study. The values of vessel intimal-media thickness(IMT), the size of plaque, vessel diameter, percentage of diameter stenosis, percentage of the peak systolic velocity acceleration at stenosis orifice, and velocity wave pattern were obtained with CDFI. The study indicated that the incidence of vasculer disease in the lower extremities as shown by CDFI was higher than that as assessed by clinical manifestations only. By CDFI,the severity of the stenosis or the obstructive lesions of blood wessels in lower extremities was better evaluated,moreover quantitative indexes for clinical diagnosis were provided.
