There was no ≥50% stenosis in the ipsilateral inflow tract confirmed by DSA or CTA; 8. The reference vessel diameter of target lesion was 2.0-4.0 mm; 9.

Exclusion criteria:

1. Pregnant women; 2. Primitive submalleolar lesions; 3. Patients who have had or are planning a major amputation; 4. Life expectancy <1 year; 5. History of stroke or myocardial infarction within 3 months before surgery; 6. Severe renal insufficiency with serum creatinine more than 2 times the upper limit of normal; 7. Patients with acute thrombosis requiring thrombolysis or thrombectomy; 8. Patients requiring simultaneous intervention of both lower limbs; 9. Known allergy or intolerance to rapamycin, paclitaxel, contrast media, or antiplatelet drugs; 10. Patients with previous history of coagulopathy or thrombocytopenic purpura; 11. Vascular access infection or active systemic infection; 12. Surgically treated restenosis; 13. Those who had participated or were participating in clinical trials of other drugs or medical devices within three months before screening; 14. Patients with severe calcification (PACSS score: grade 4); 15. No outflow tract of target lesion below ankle joint; 16. It was considered by the investigator that the patient might not adhere to the trial protocol or had other conditions that precluded participation in the trial.
