Occlusive Disease of Lower Extremity
Occlusive Disease of Lower Extremity
This is a randomized study comparing stent and plaque excision systems in treatment of Arteriosclerosis occlusive disease of lower extremity (superficial femoral or popliteal artery)
This is a randomized study comparing balloon angioplasty adjunctive stent and plaque excision systems in treatment of Arteriosclerosis occlusive disease of lower extremity (superficial femoral or popliteal artery)
Patients were included if they were de novo stenosis>70% or occlusion of the femoropopliteal at least 18 years of age and referred for claudication (Rutherford-Becker class II-III) or critical limb ischemia (Rutherford-Becker class IV-V). They were excluded if they had one or more of the following: 1. Acute or subacute lower limb ischemia; 2. Severe calcification lesions; 3. Total occlusions lesions more significant than 10 cm or total occlusion lesions with a suspicion of subintimal wire recanalization 4. untreated ipsilateral iliac artery stenosis>70%, or the distal runoff artery <1 root; 5. Previously lower extremity intervention or surgical graft artery bypass; 6. Severe renal insufficiency, creatinine level greater than 2.5 mg/dL; 7. The patient's platelet count is less than 100,000/uL, antiplatelet or anticoagulant contraindications to required medications; 8. Patients with immune system diseases or malignant tumours; 9. ongoing active infection 10. decompensated congestive heart failure or acute coronary syndrome; 11. Unwillingness to return for future follow-up visits
