摘　　要：BACKGROUND The diagnosis of peripheral arteriopathy in the diabetic foot is complicated by diabetes and its advanced complications.It has been found that diabetic foot can be categorized into arterial stenosis and non-arterial stenosis,both of which have significant differences in hemodynamic characteristics.AIM To evaluate the early hemodynamic changes in diabetic foot patients with nonarterial stenosis and arterial stenosis treated by tibial transverse transport(TTT)using high-frequency color Doppler ultrasonography(HFCDU)and a laser Doppler flowmeter.METHODS Twenty-five patients with Wagner grades 3-5 diabetic foot ulcers were treated with TTT,and the wound healing time and rate were recorded.Patients were grouped according to the results of preoperative lower-extremity ultrasonography.Cases with≥50%stenosis in any of the femoral,popliteal,posterior tibial,anterior tibial,and peroneal arteries of the affected limb were classified as the arterial stenosis group(n=16);otherwise,they were classified as the nonarterial stenosis group(n=9).Before and one month after surgery,HFCDU was used to evaluate the degree of lower limb artery lesions and hemodynamic changes in patients.The degree of femoral-popliteal atherosclerotic stenosis,the degree of vascular stenosis and occlusion of the lower-knee outflow tract,and the degree of medial arterial calcification were scored;the three scores were added together to obtain the total score of lower extremity arteriopathy.PeriScanPIM3,a laser Doppler flowmeter system,was used to detect alterations in plantar microcirculation before and 1 mo after surgery.Wound healing and hemodynamic indices were compared between the two groups.RESULTS The wound healing time of the diabetic foot was significantly shorter in the nonarterial stenosis group than in the arterial stenosis group(47.8±13 vs 85.8±26,P<0.05),and the wound healing rate of both groups was 100%.The preoperative total lower extremity arteriopathy scores were lower in the nonarterial stenosis group than those in the arte
