Ultrasound diagnosis and related factors analysis of lower limb arterial lesions in patients with type 2 diabetes

Abstract

Objective To investigate the color Doppler flow imaging （CDFI） diagnosis value and related factors analysis of lower limb arterial lesions in patients with type 2 diabetes. Methods 70 cases with type 2 diabetes as observation group, 60 not-type 2 diabetes patients as control group in the same period were selected,who were given lower limb artery CDFI examination and comparison. Results Lower limb artery blood wall intima-media thickness （IMT） abnormal, atherosclerotic plaques, luminal stenosis, occlusion detection rate of the observation group were 82. 86% ,60.0% ,22.86% ,they were significantly higher than 28.33%, 16.67% ,5.0% of the control group（ x^2 = 4.38,12.84,7.53, all P 〈 0. 05 ） ; the lower limb artery plaque location of the observation group often was seen in the femoral artery, posterior tibialis artery and the anterior tibialis, dorsalis pedis artery in 42.86%, 10.0% ,42.86%, 48.57% ,compared with 11.67%,6.67%,3.33%,3.33% of the control group, there were significant differences （ x^2 = 4.87,12.75,13.97, all P 〈 0.05 ）. In the observation group, the related factors of type 2 diabetes lower limb arterial pathological including age, blood pressure, glycosylated hemoglobin, blood lipid （ TC, TG, HDL-C）, there were significant differences compared with the control group （t = 13.26,5.34,4.00,89.00,6.54,7.54, all P 〈 0.05 ）. Conclusion The CDFI examination is a reliable diagnosis means of patients with type 2 diabetes lower limb artery lesions,which can determine the lesion site,length,jam extent and vascular anatomical abnormalities, and has an im- portant clinical value.
