Diagnostic value of high frequency color doppler ultrasound for lower limb artery lesions in patients with diabetes

Abstract

Objective To explore the clinical value of high frequency color doppler ultrasound in the diagnosis of lower limb artery pathological changes of diabetes.Methods Linear array of high frequency probe was used in regular line double lower limbs artery ultrasound examination in 102 cases with diabetes (observation group) and 98 healthy people(control group).The lower limb artery(including femoral artery,popliteal artery,posterior tibial artery,the tibia and dorsalis pedis artery)before the intima-media thickness (IMT)were measured,and the presence of plaque,the plaque nature,the degree of luminal stenosis or occlusion of the judgment and hemodynamic changes were observed.Results In observation group,the femoral artery plaque detection rate was 22％,popliteal artery plaque detection rate was 36％,posterior tibial artery plaque detection rate was 39％,pretibial artery plaque detection rate was 38％,dorsalis pedis artery plaque detection rate was 45％.In control group,the femoral artery plaque detection rate was 9％,popliteal artery plaque detection rate was 7％,posterior tibial artery plaque detection rate was 10％,pretibial artery plaque detection rate was 13％,dorsalis pedis artery plaque detection rate was 16％.In the observation group,lower limb artery plaque caused mild stenosis in 31 cases,moderate stenosis 16 cases,severe stenosis 11 cases,block 4 cases.In the control group,9 cases had mild stenosis caused by lower limb artery plaque,moderate stenosis 5 cases,3 cases with severe stenosis and occlusion in 0 case.In the observation group,lower limb artery soft spot 14,hard spots in 19,41 mixed plaques.In the control group,lower limb artery soft spot 4,hard spot 8,11 mixed plaques.Conclusion Lower limb artery pathological changes is closely related with diabetes,especially the artery stenosis and block the knee can predict the development of diabetes.
