Objective:To explore the therapeutic effect of drug-coated balloon technique for the treatment of arteriosclerosis obliterans in lower extremities.Methods:A total of 64 patients with definite diagnosis of lower extremity arteriosclerosis obliterans who were admitted to the hospital from December 2016 to January 2018 were randomly divided into a control group and a study group.They were treated with bare metal stents and drug-coated balloons,Then compared the treatment effects of the two groups.Results:The minimum lumen diameter and sputum index after treatment in the two groups were significantly different from those before treatment(P<0.05).In the control group,target vessel revascularization occurred in 9 cases(28.13%),and target vessel revascularization occurred in 1 patient in the experimental group(3.12%),which with significant difference(P<0.05).The study group significantly reduced the release of the stent or shortened the length of the stent;both patients did not have intraoperative death,surgical-related death 30 days after surgery,limb limb amputation;There were 4 cases of secondary thrombosis(3.12%)in the control group and only 1 case of secondary thrombosis(12.50%)in the observation group.There was a significant difference between the two groups(P<0.05).Conclusion:The use of drug-coated balloon therapy for patients with lower extremity arteriosclerosis obliterans could significantly improve late lumen loss,expand the minimum lumen diameter,increase the ankle index,and reduce target vessel revascularization,reducing stent release or shortening the release.The length of the stent was significant and it was worthy of promotion and application.
