入选标准
- •Patients over 18 years with critical lower limb ischemia,
- •Ruhtherford 3 or higher,
- •with angiographic documentation of greater than 70% or occlusion in the superficial femoral artery,
- •with a maximum extension of 10 cm stenosis.
- •The popliteal artery and at least one leg artery must be patent.
排除标准
- •Pregnancy,
- •thrombophilia,
- •coagulation disorders,
- •presence of active or recent bleeding,
- •severe allergy to iodinated contrast,
- •renal or hepatic disease,
- •acute limb ischemia,
- •prior surgical bypass or angioplasty (with or without stent) on the target artery,
- •obstructive disease (stenosis> 50%) of the aortoiliac segment ipsilateral to the target (if the aortoiliac is pre-treated, the patient may be included)
结局指标
主要结局
Primary patency
时间窗: 12 months
Evaluations will be conducted after 3, 6 and 12 months of the procedure. The ultrasonographic evaluation of the degree of stenosis will use the Systolic Velocity Index (division of the velocity of flow at the point of greatest stenosis by the velocity of flow in normal prior segment). Rates higher than 2.4 indicate stenosis greater than 50%
次要结局
- Acute myocardial infarct(12 months)
- Death(12 months)
- Target Lesion Revascularization(12 months)
- Ankle braquial Index(12 months)
- Rutherford classification(12 months)
- Stent fracture(12 months)
- Amputation(12 months)
