Clinical Trial Summary

DCB can maximize the patency rate of blood vessels on the basis of intraluminal DA. DA+DCB treatment is effective and safe [8], and the advantages of DA and DCB in the treatment of severe calcification and occlusive disease across joints and lower extremities have been confirmed. The combined application of DA and DCB in the treatment of peripheral arterial disease has a good early and mid-term effect. Konstantinos et al. reported that DARRT has a higher first-phase patency rate compared with DCB. A retrospective study by Sebastian et al. showed that compared with PTA after DA, the combination of DA and DCB has a better event-free survival rate after 12 months of follow-up. Therefore, DA combined with DCB therapy may be one of the best and most promising methods for the treatment of lower extremity ASO.
