Abstract

Abstract: In order to study the clinical value of ultrasound-guided interventional therapy in treatment of lower extremity arteriosclerosis obliterans (LEASO) in elderly patients, a total of 190 elderly patients with LEASO were enrolled, and the diseased blood vessels of all patients were examined by ultrasound. The ultrasound imaging findings of the lesions were observed and the vascular stenosis was evaluated. Ultrasound was used to evaluate the peak systolic blood flow velocity (PSV) and the hemodynamic changes of the dorsal foot artery before and after vascular intervention, and statistical analysis was performed. The results showed that compared with DSA,there was no significant difference between the detection rate of ultrasound for the degree of stenosis and the detection rate of lesions of different blood vessels (P>0.05). After treatment,the PSV at the lesion and the hemodynamic indicators of the dorsal foot artery ultrasound were significantly different from those before treatment. In summary, Ultrasound is an effective diagnostic method for LEASO, and it is also an effective detection method to monitor elderly patients with LEASO during vascular interventional therapy.

Key words: ultrasound, interventional therapy, elderly patients, lower extremity arteriosclerosis obliterans (LEASO)
