To Probe Into The Clinical Value Of Color Doppler Ultrasonography In Screening Periphery Artery Disease In Patients With Diabetes Mellitus

ObjectiveTo probe into the clinical application value of color Doppler ultrasound in the screening of periphery artery disease(PAD)in patients with diabetes mellitus,and provide theoretical basis for early identification of lesions,timely diagnosis,and effective treatment measures.METHODSpatients with diabetes mellitus admitted to the Department of Endocrinology at the hospital were enrolled as subjects and grouped according to whether they had foot ulcers at the time of admission.Patients with foot ulcers were divided into the ulcer group.Patients without foot ulcers were divided into the control group.There were 83 patients in the ulcer group and 223 patients in the control group.The general data and laboratory results of the two groups were retrospectively analyzed.The type of vascular lesions of the lower extremities was examined with an ultrasonic Doppler diagnostic apparatus and the arterial plaque,stenosis,obliteration and blood flows of the lower extremities features were recorded.Results(1)Diabetic duration and HbA1 c in the ulcer group were higher than those in the control group(P<0.05),and the proportion of patients with hypertension was higher than that in the control group(P<0.05).(2)The blood vessel disease rate of the lower extremities in the ulcer group was higher than that in the control group(P<0.05),in the ulcer group,there were plaques and mild to moderate stenosis above the knee,and the arterial lesions of the lower extremities in the ulcer group were more severe than those in the controlgroup(P<0.05).(3)Bilateral branch arteries could occur in both groups.Different degrees of lesions,abnormal blood flow or occlusion occurred in the radial artery,anterior tibial artery,posterior tibial artery,dorsalis pedis artery,and the probability of abnormal blood flow in the branches of the ulcer group was significantly higher than that in the control group.There was a statistical difference between the two groups(P<0.05).(4)In the ulcer group,stenosis and occlusion of the anterior tibial artery and dorsalis pedis artery were more common,and the probability of stenosis in the anterior tibial and dorsal arteries was higher than that in the posterior tibial artery.(P < 0.05),there was no statistically significant difference in the probability of stenosis or occlusion of the blood vessel of the same name on the ipsilateral side and the established side(P> 0.05).Conclusion1.The occurrence of diabetic foot ulcers is positively correlated with the duration of diabetes,glycosylated hemoglobin,and hypertension.2.Vascular lesions of the lower extremities are risk factors for the development of diabetic foot ulcers.Diabetic foot ulcers are characterized by plaques and mild to moderate stenosis in the lower extremity knee.3.The lower extremities of diabetic patients often involve bilateral branch arteries,and those with severe stenosis or occlusion are more common in the radial artery,anterior tibial artery,posterior tibial artery,and dorsalispedis artery.4,both limb and limb have serious vascular lesions,presacral or(and)dorsal arterial disease caused by the possibility of diabetic foot.
