Objective: To observe the efficacy of drug -coated balloon (DCB) in the treatment of long -segment arterial stenosis in lower extremity. Methods: Were retrospectively analyzed in February 2017 to January 2018,the First Hospital Affiliated to China Medical University of vascular surgical treated 80 patients with lower limb sclerosis of arterial congee appearance (lesion length>10 cm), accept the DCB and stents (BMS) treatment, compared two groups of patients with preoperative and postoperative issue patency rate of target lesion, ABI, Rutherford, amputation rate and the change of clinical symptoms and quality of life. Results: There were 60 cases in DCB group,20 cases in BMS group and 80 cases in BMS group. The patency rate of DCB group was 83.33% and 75.00% at 6 and 12 months after operation. The patency rate was 85.00% and 65.00% in the BMS group at 6 and 12 months after surgery. ABI, walking distance, Rutherford grade and clinical symptoms were significantly improved in the two groups compared with those before surgery. During the operation, 1 patient in the DCB group presented flow limiting interlayer and 1 patient still had>50% stenosis after predilation, and then underwent stent implantation for remediation. Conclusion: The treatment of lower limb arterial stenosis with DCB can obtain better near -and medium-term clinical efficacy.
