Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In order to assessment the safety and efficacy of debulking atherectomy versus stent angioplasty for limb ischaemia of diabetic lower limb atherosclerosis-occlusive disease, we intend to conduct a prospective, multicenter, randomized controlled, non-inferiority trial. The main surgical methods included stent angioplasty group (Nickel-titanium self-expanding bare stent) and debulking atherectomy group (Excimer laser atherectomy combined with drug-coated balloon angioplasty). The sample size was 244 patients, and the patients were followed up at 30 days, 180 days, and 365 days after operation.
