A STUDY OF VASCULAR LESIONS IN THE LOWER EXTREMITIES IN TYPE 2 DIABETIC MELLITUS BY COLOR DOPPLER FLOW IMAGING / 解放军医学杂志

ABSTRACT

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.
