结局指标
主要结局
Primary Patency Rate
时间窗: 12 months
Primary patency is defined as no significant reduction of flow detectable by Duplex ultrasound through the index lesion and no further clinically driven target vessel revascularization performed in the interim. Significant reduction of flow is binary restenosis defined as the diameter stenosis \>50% with a peak systolic velocity ratio \>2.4 as measured by Duplex ultrasound.
次要结局
- Technical success(1 day)
- Major Adverse Events(12 months)
- freedom from clinically-driven TLR(12 months)
- Limb Salvage Rate(12 months)
