结局指标
主要结局
Salvage limb rate (for CLI patients)
时间窗: 12 months after the index procedure
Limb Salvage is defined as the freedom from secondary major amputation
Primary patency of claudicant patients
时间窗: 12 months after the index procedure
Claudicant patients (Rutherford C1-3), primary patency defined as PSVR（peak systolic velocity ratio) ≤2.4, absence of restenosis \>50% based on an imaging study (Duplex ultrasound, CT angiography or catheter angiography) at 12 months
次要结局
- TcpO2(12 months)
- Wagnar classification(12 months)
- ABI(12 months)
- Index Limb Ischemia at 12-month Follow up(12 months)
- Rutherford classification(12 months)
- Major Adverse Events at 12-month Post Procedure(12 months)
- Target vessel revascularization rate(12 months)
