Abstract ObjectiveTo explore the effectiveness of application of color Doppler ultrasound combined with ankle brachial index (ABI)in the diagnosis of lower extremity vascular diseases in elderly patients,so as to provide reference for clinical diagnosis.MethodsAltogether 60 cases of elderly patients with lower extremity vascular disease who were treated in our hospital from January 2016 to March 2017 and 45 healthy cases who were underwent health examinations during the same period of time were selected as the object of this research;ultrasonic inspection with color Doppler ultrasonic diagnostic apparatus and ABI measurement with full-automatic arteriosclerosis detector were performed for all the subjects;the color Doppler ultrasound examination and ABI measurement results and peripheral arterial disease(PAD)detection rate acquired by using different methods were compared between two groups of patients.ResultsThe rough intima,IMT (Intima-Media Thickness)thickening,plaque formation,blood filling defect,lumen stenosis and lumen occlusion of the observation group examined by using ultrasound were significantly higher than those of control group,with statistically significant difference (P＜0.05);the detection rate of patients with ABI≤0.9 of the observation group was significantly higher than that of control group;and the detection rate of patients with 0.9＜ABI≤1.3 of the observation group was significantly lower than that of control group,with statistically significant difference (P＜0.05);the detection rate of PAD by using the combination of color Doppler ultrasound and ABI measurement was 88.3%(53/60),significantly higher than that of single color Doppler ultrasound examination (66.7%,40/60)and single ABI(41.7%,25/60),with statistically significant difference(P＜0.05).ConclusionApplication of color Doppler ultrasound combined with ankle brachial index in the diagnosis of lower extremity vascular disease in elderly patients is helpful for the accurate diagnosis of lower extremity vascular disease,which is worthy of clinical application.
